FM 2021 Fantasy Scenarios - World Super League (WSL) - FM21 edition

FM21.4 version:


Welcome to the World Super League (WSL) for FM21, the most downloaded and highly acclaimed Super League mod of the last 4 years (with over 50,000 downloads and subscriptions).

WSL is a total conversion 'Super League' where over 1000 clubs from 73 countries have all come together to play in England.

If you find the base game too easy, or you just want a new challenge, then this it the ultimate test of your management and tactical skills.

This is also one of the highest quality and most advanced Super League mods available; written by a software developer with many years experience; (ESL17, WSL18, WSL19, WSL20 and WSL20 XE), this is the largest and most ambitious version yet.

This mod features high quality custom leagues, cups, rules, awards and custom graphics (custom made logos and backgrounds). Over 800 clubs from around the world are included, as well as all 160 playable clubs from England and more. 140 clubs compete in a the UEFA Champion League and over 300 clubs compete in the UEFA Europa League; as well as many other leagues, cups, reserve and youth cups etc.

It's a true labour of love that takes several weeks to complete, but provides me with some of the most memorable moments of my life.
Not only do I create this mod every year for others to enjoy, but I also play it myself; last year I played the WSL for over 3,300 hours.

League Structure

Overall the league structure is designed to provide the maximum challenge for clubs in the Premier League.

Unlike normal leagues and other super leagues, the WSL league structure is "wider" and not "deeper". There are a few reasons for this:

  1. You can climb the ladder a lot faster.
  2. There is a lot of competition to get into the Premier League, it's very difficult but also very rewarding.
  3. The Premier League clubs can send players on loan to good quality clubs below them
  4. The top 2 tiers (PL + SL1) feature 140 clubs, that include the best clubs in the world, which are all "Premier League Quality" clubs; and they all play in a custom (but familiar) UEFA Champions League.

This structure is based on the WSL Extreme Edition for FM20 from last year which worked very well for me, but with the addition of 96 new clubs.

Premier League - 20 clubs
Super League 1 - 6 Divisions - 120 clubs
Super League 2 - 12 Divisions - 288 clubs
Super League 3 - 8 Divisions - 192 clubs
Super League 4 - 8 Divisions - 192 clubs
Super League 5 - 4 Divisions - 96 clubs
Super League 6 - 4 Divisions - 96 clubs

UEFA Leagues & FA Cups

UEFA Champions League - 140 clubs
UEFA Europa League - 288 clubs
UEFA Europa League 2 - 384 clubs

FA Cup - All 1004 clubs

Super League Cup - 140 clubs
Super League 2 Cup - 288 clubs
Super League 3 Cup - 192 clubs
Super League 4 Cup - 192 clubs
Super League 5 Cup - 96 clubs
Super League 6 Cup - 96 clubs

Super League 6 Cup180,000 (£)150,000 (£)

In the lower leagues, winning a "Super League 6 Cup" round will give you a huge financial boost. And winning the Super League 6 Cup is more valuable than winning the league. But the league cups value starts to decrease as you progress higher up the leagues. In higher leagues the Europa and Champions League money is much higher than the league cups.

There are many other bonuses, for example, getting into the UEFA Champions League group stage gets you 20,000,000 (£). There are other round bonuses, and every league position in all leagues has some value.

Clubs in the Premier League should get around £200M ~ £300M, for league, cup and TV bonuses. But this is offset by higher transfer fees (if you include the transfer fee addon), as I've seen Harry Kane being sold for over £200M.

Major changes:

  • Expanded the Europa League 2 and removed the Europa League 3 & 4
  • B-Teams and U19 are replaced by Reserve and U18 teams

Minor changes:

  • Improve the depth and quality of the league structure
  • Rebalance income and prize money.
  • League depth has increased from 6 levels to 7 levels.
  • Removed the Europa Leagues from the lower divisions.

New Super League Cups

The main differences from the FM20 version is that I've removed the lower "Europa Leagues", and replaced them with "Super League Cup".
My feeling is that the "Europa Leagues" for lower division are not really necessary, because they usually just take time away from the league, which is the most important and they add a lot of processing.
The "Super League Cup" is much faster to process because it doesn't have a group stage, just a simple knockout.
The Champions League and Europa League remains for the higher divisions.

B-Teams & U19 teams replaced by Reserve and U18 teams

I noticed that the AI didn't have many 19 year old players in the U19 squads. They were just filled with mostly U18 players.
So I want to try and see what the difference will be if I switch to U18 teams instead.

The B-Team to Reserve team switch is mainly because the Editor has some limitations with the "simple reserve team" rules and B-Teams.
The Reserve team system doesn't have a promotion/relegation, they are just based on the 1st team's league.
When I started a new game, it was fun and interesting to also manage the B-Teams, but eventually it becomes too much effort to manage both teams properly.
I might go back to B-Teams with promotion/relegation in the next version.

What's next?

Next version?

I will create a new version after the FM21 DB update; which usually comes out in February after the January transfer window.
I wanted to release this earlier than normal to get some feedback on new ideas, but I think it should be fully functional and enjoyable.

Known issues.

1. There are some issues with the FM21 editor which I have reported directly to SI. I have a work around for most of them. They are not severe.
2. There is some internal issue with some Reserve teams, typically from clubs in China and Uruguay. I created the Reserve teams, but they don't show up. I don't have a work around for this yet. I think some internal config file might be overwriting them.

Optional Rebalance "addon" Files included

Due to popular demand, I've separated some of the changes I usually make, into small "addon" files, included in the download.
When creating your new game, you will need to add / select these in addition to the core file.

I personally play with all these addons enabled.

Some of these are highly recommended, because some of the ratings of the base game are only balanced between clubs in their country / league, and they are not balanced globally, so they don't translate well in the context of a Super League. Some of them are controversial, like the Nation Youth Ratings and Youth Recruitment files, which together should increase the number of wonderkids created. I personally enjoy having a lot of wonderkids, because the league structure, the number of clubs and all the prize money available still makes it very challenging to sign them because there is a lot of competition between the clubs.

Rebalance Nation Youth Ratings

Rebalances all the nations Youth Ratings, based on a sliding scale derived from the nations average position in the official FIFA World Rankings.
You are welcome to test/simulate the game to determine the effect this has on the overall youth production and distribution.

Rebalance Transfer Values

Because there is more money for the top clubs in the game world, there is also higher demand for top class players.
This increased demand pushes up the global transfer value of the elite players.

171-180 - 70,000,000 (£) -> 80,000,000 (£)
181-190 - 80,000,000 (£) -> 105,000,000 (£)
191-200 - 90,000,000 (£) -> 140,000,000 (£)

AI Managers Boost

12 managers get a minor boost to their stats, including Jurgen Klopp and Pep Guardiola. This is just a minor boost, to make them a little more competitive.
The scenario is actually very difficult for AI Managers, as even the slightest slip up and they get sacked. It's just a few tweeks, usually about 5 changes.

FM21 Transfers (by FMTU)

This is the transfers file extracted from FMTU. This file was valid upto 10th January, and includes Mauricio Pochettino to PSG.
There are other files available, all credit goes to FMTU and pr0!
Not all the files are compatible with WSL.
FM21 Transfers & Data Update Packs by pr0 + FMTU

New Wonderkids (by pr0) Maxed

The pr0 + FMTU file includes a small "wonderkids" file that includes 11 new real life wonderkids. I've just taken that file and boosted the 11 wonderkids PA rating to -10 (170~200). If you want the original file, please download it from the FM21 Transfers & Data Update Packs by pr0 + FMTU!

Boost Training Facilities

This gives a boost to most of the training facilities of the other clubs. I just don't understand how Club Brugge and Benfica have level 20 training facilities, but Real Madrid and Barcelona have level 18. The issue is that the AI managers will almost never upgrade their facilities. So it's a bit unfair when you can take a lower league club, and have world class facilities better than Real Madrid and Barcelona within a few years. I would prefer to be on equal terms with those clubs. This update just gives the AI managers and clubs a better chance to develop players.

Boost Youth Recruitment to 20

This is one of the most controvertial updates I usually include.

It will max-out the Youth Recruitment of almost all clubs. There are HUGE imbalances in the base game with-regards-to Youth Recruitment between the countries. Each country's clubs are just balanced between the clubs in that country and not globally (I think each country has editors that have different opinions and ideas). It's a huge issue when you create a super league, because now all the clubs compete together, and they have not been properly balanced against each other. And, because I like to have a lot of "wonderkids" in my game, if you don't like that, then just don't include this file when you start a new save!

For example, Beşiktaş and Galatasaray have a Youth Recruitment of 6 and 8 respectively. These are the top 2 clubs in Turkey with a reputation over 7000.

Then you have 155 clubs with a 20 Youth Rating in the base game, some of those clubs I've never even heard of. Only 6 clubs of the 155 clubs have a reputation better than Beşiktaş and Galatasaray. 97 of those clubs have a reputation below 4000, which is League Two level. If you look at how the clubs in Turkey have been rated, they are completely under-rated and imbalanced.

Because there are other factors involved when generating Youth players, I just prefer to set this to 20 for all the clubs over 4000 reputation.

Here is a table to show the difference in the number of youth players generated in the first year.

RatingDefault gameWith my addons
PA > 19024
PA > 180733
PA > 1702971
PA > 16070137
PA > 150185327

Please note that these numbers decrease significantly the following year. (There are a lot of newgens created in the first year, but this number decreases significantly with time).

Also take into account how many clubs there are. There are A LOT more clubs than your typical game, and a lot more competition for young talent.

And just because the game generates a high PA player, doesn't mean that player will be any good.
For instance, the default game generated a full-back player with 199 PA, but he had high injury rate, low concentration, low consistency and very slow.
I would rather have more wonderkids generated, so some of them might actually be good. A high PA doesn't mean the player will actually be any good!

What most people don't realize is that the way that "humans" manually optimize players (in the editor), is actually very different to how the game generates and trains newgen / regen players. For example, you could play the game for 1000 years, and you would NEVER create a player like Messi or Ronaldo. Their stats have been so heavily optimized, and carefully fine tuned, that the game itself will never be able to create a player like that, even if you had a million players with 200 PA and 200 CA, the game's player generation algorithm and the way it trains players just cannot create another Messi or Ronaldo.

There are some stats that just don't develop properly. So I would rather have a larger pool of players, so that a few of them actually generate a player worth buying.


Minor Update - v1.1 - 12 January

1) Made some minor scheduling improvements. Mainly to the top Super League Cup.
2) Rebalanced all Super League Cups prize money.

Minor Update - v1.2 - 13 January

NO changes to the core files, only a few more "addons" added and a few more mini stadium photos.

Critical Update - v1.3 - 14 January

The issue found by RetraC has been resolved, where clubs in the lower league get income from the Premier League.
This had to do with the "Last Division" of the clubs being in the top tier of their countries, now the clubs are in a different country and league.
Even though their "Last Division" was a completely different league, the game was incorrectly giving them income from the Premier League.
I just cleared all the clubs previous / Last Division values and positions.

Thanks again to RetraC for reporting the issue.

Minor Update - v1.4 - 15 January

Added a custom facepack of the wonderkids addon. There are 8 wonderkids, 2 photos are real, the others are fake images because some of the kids are extremely young, and there not many photos available online.
This also includes a small fix to the wonderkids file, where 2 players were assigned to clubs that don't exist in the WSL, so they are not always loaded.
The wonderkids facepack can be added to previous versions, if you started a save on a previous version, because the ID's will be the same.

Please check this page regularly for any further updates!

    Thanks - I was able to get through it in the end.

    There is a similar scheduling issue with the FA Cup Round 5, which is also right in the middle of the international break. I'm guessing there will be more similar issues as the game moves along.

    All in all, I've found the most fun of my experimental saves to be playing with Hallam. There's nothing quite like trying to compete in this league with a team that consists of 100% trialists!
  • mircopozzo's avatar
    OK thanks. Will there be major changes?
  • Darthfurion's avatar
    I will upload a new version for FM21.3 in about 1~2 weeks. I have already begun with the conversion.
  • fmguy23's avatar
    Is this available on mac? If so, how can I download it?
  • fmguy23's avatar
    I can't seem to find the database when I try to start the save. I have the WSL file in the editor data folder. Could someone help me with what I am missing? Does it have something to do with the new update?
  • trilla_ruben's avatar
    cant wait to play this any idea when it'll be compatible with the new update?
  • mircopozzo's avatar
    last night the winter update came out. when will the new version of the World Super League come out?
  • ncpoomkung's avatar
    This is is the best db mod I've ever used. But it greatly increase the processing time. With only super league 2 enable with large database, I got only 3 star. haha
  • Thorbain's avatar
    Really liked last years version with the 9 tiers, do you have any plans moving forward to release another version of the fm21 database with more than the 7 tiers that you have in this one?
  • mircopozzo's avatar
    hello I noticed that in the meeting of the corporate vision at the beginning of the career in the following years the goals refer to the championships of the nation in which the team plays (for example Dortmund win the Bundesliga in 2021/22). Can you solve it for the next version?
  • Darthfurion's avatar

    I know it's inconvenient, but I don't think it's "save-destroying". It's really just 1 game, and I'm sorry about that. It's hard to predict every possiblity. If you really want, you can just "replay" that game a few times until your team wins. I also think the other team might have International players as well.

    I don't think it will stop you from getting into the Premier League. I wouldn't worry too much about the Europa League 2. Try to focus on the league games until you get into the Premier League. It's nice to make some extra money from the Europa League 2 games, but sometimes they can be bad for your league games, especially when your best players get injured in the Europa League 2 games.

    But I will look into the Europa League 2 games for future versions. Thanks for the feedback!
  • dnzg66's avatar
    I've located an issue that I consider to be save-destroying.

    I managed to get Jiangsu Suning up to the 3rd round of the Europa League 2. However, the second leg of our 3rd round game is scheduled for the middle of the international break. We've got 15 players on international duty, which means that we have to dip into our reserves just to put a competitive team on the pitch.

    There is no way to postpone this match since the 4th round draw is on the same day.

    This is a huge problem, particularly due to the amount of money on the line for reaching the group stage.

    My wish is that international play could be completely removed from this system, as it makes very little sense given the nature of the World Super League. However, I'm worried that SI has programmed the game so that this is impossible.

    At any rate, it is extremely frustrating. We have the better side, and are coming in with a 3 goal advantage, but we can't win the tie because our players are simply not available.
  • cdq0070's avatar
    My English is not good, the following is a Google machine translation.

    I did it myself to solve the problem that the reserve team of some clubs could not participate in the reserve league correctly.

    Clear the stadium, number of spectators, minimum attendance and other settings of the reserve team of all clubs to be created, and delete all existing club reserve teams, including the second team, B team, etc., after which all clubs' reserve teams can participate correctly Reserve League.
  • dnzg66's avatar
    No worries! I think it plays just great.
  • Darthfurion's avatar

    Thanks for the feedback. I'm aware of the U18 limitations where some clubs might not have an U18 team. I'm using the "simple" / "basic" U18 and reserve league setup / rules, where the game automatically decides which U18 clubs to create and what divisions to put them into. The game might ask you if you want to join an U18/Reserve league. Sometimes it might not ask. I'm not really sure under what conditions it decides this. But I've set higher divisions to always require these teams, I'm hoping it will make sure to always create and assign them to a league in higher divisions.

    I use the basic rules, because it takes a LONG time to move all the youth players from ALL teams back into their parent team. Especially the Spanish teams. It actually takes me longer to do this, than to create the whole WSL.

    Anyway, I hope it's not a major inconvenience for you.
  • dnzg66's avatar
    A quick note on two bugs:

    - As mentioned above, some Chinese teams have reserve squads that do not play in any league. I noticed this with Jiangsu Suning. I'm not sure if this problem persists throughout an entire save, or if it fixes itself after the first season. This isn't a huge issue, of course, since a lot of B-teams in the vanilla game also don't have a competition. Note, though, that the reserve team does exist - the description is a tad inaccurate in this respect.

    - Kawasaki Frontale's Under 18 team does not play in any league. FC Tokyo has the same problem; I'm not sure if other Japanese teams also have Under 18 squads without a league. Other National League East Under 18 teams do play in an English Under 18s Group like they should. Again, this isn't a huge issue - I just left Kawasaki's U18 team empty without any staff and used my Reserves squad as an U18 squad instead.

    I'm guessing that both problems are due to this year's rather eccentric pre-game editor and strange things that SI decided to hardcode for some reason. Luckily, none of these are really game breaking in any sense, unless having your 15 year olds play in the reserves gives you anxiety.
  • Nanox7's avatar
    What a datebase so fun to play and lot of challenge.
    Thanks mate !
    I recommend others to give it a try.
  • wikifirelord's avatar
    Always loved your Super League DB. There is just 1 issue I have with it. And that is that all the clubs in it still have all their trophies.

    Which can kind off ruin immersion. So maybe delete all the trophies from the teams?
  • Webbmode's avatar
    Agree with @dnzg66

    This database is fantastic, but I'd love to see the wealth of lower league english teams trimmed down a bit to include other small league teams around the world or europe.

    I imagine in the editor it'd be easy to swap some of those teams in/out, but I don't want to break the database by doing so
  • dnzg66's avatar
    After spending a weekend playing around with this, I can unequivocally say that this is the most fun I've ever had with Football Manager. It's a lot more fun to play with teams at any level in this setup than in the base game, both because you can achieve higher things in your career and because you don't have to worry about stupid arbitrary squad registration rules in various competitions.

    This is so much more fun than the base game that I plan on waiting to buy FM22 until after Darthfurion's latest update to this project comes out.

    My only request is for more lower-reputation non-English clubs. My mother was born in Eskilstuna, Sweden, for example - but AFC Eskilstuna is not included in this game. It would be nice to see teams around that level from the rest of Europe added to SL6 in the future - as well as some from other parts of the world.

    By the way, I strongly recommend playing with all of the recommended add-ons. That will keep you from starting with Manchester City and immediately buying Haaland and everybody on your list of wonderkids.
  • _Azzam's avatar
    Hi, bro
    How can I load the database in Creat-a-Club mode?
    or it is not possible?
  • CasperFM's avatar
    I really like this concept mate! Gonna try it out with my local team and try to take them to the top!
  • dnzg66's avatar
    All I can say is that I really recommend this if you want a good FM challenge. Darthfurion really did a great job in creating good balance and a great schedule that is fun to play.

    If you think FM21 is too easy, go manage Hallam in this league. Have fun trying to be competitive on £500 a week with no transfer budget!
  • Darthfurion's avatar

    I think Germany and Japan are disabled in the base game, and you need a mod to unlock them.

    Have you installed the Real Names fix?

    If the Real Name fix that I listed in "Recommended & Compatible mods" doesn't work for you, then try the one on sortitoutsi. Try one of these:
  • RexfelisLOC's avatar
    Hello, love your WSL addon...always makes FM more challenging and interesting. I noticed Germany is not available as a national team. Is this a WSL database issue or an issue with FM21?
