To help explain the tactic and how it works as well as all the results of my various played and simulated saves, I created a tactics video over on my YouTube channel LSPLaysFM! You can find the video below:
How The Tactic Works
I initially created another 4-1-2-1-2 Narrow Diamond Tactic a few weeks back, but I have since adapted this and now the new Unbreakable Diamond here is its successor and in my opinion is far better then ever!
I used this tactic in a personal Glory Hunter-Type save with Atalanta and also tested this tactic in FM21 in a simulated test saves with Liverpool and have even been using in my Norwich City stream save over on Twitch!
You can also see in more detail below exactly how the tactic works and the results with various screenshots below as well if you’d prefer.
The tactic is a Narrow 4-1-2-1-2 Diamond formation and does rely upon its athletic wingbacks, an advanced forward who is either very pacey and/or good off the ball and then a Deep Lying Playmaker to sit in front of the defence when your Wing Backs push up in attack and who is preferably a very decent passer of the ball in order to help build attacks from the back with their range of passing.
In every save each team has performed very well, both equally as good defensively often having the best or one of the best defences in the league as well as the best attack! In the case of Norwich & Atalanta both teams have also performed arguably far above expectations. On top of that, in each of the completed saves I have tested it, the Golden Boot winner has come from the side using this tactic (Mohammed Salah & Musa Barrow).
As I have stated this tactic does phenomenally well offensively and focuses mainly upon counter attacking. However just because of that, does not mean that the tactic doesn’t work for big teams, because as shown by my Liverpool test, it most certainly does work for teams of any real size.
The tactic works as follows (check out the screenshots below to see exactly how its set up):






Just so you are aware with all other Set Pieces these are simply set to the default options as I found they worked suitably well for my sides, should you want to adapt them then feel free as doing so may make the tactic that much more powerful!
Also in addition to this, my training and opposition instructions are simply set to be handled by the Assistant. In terms though of player instructions, these are all entirely left simply to the defaults that each role provides the players with. I have not personally adapted these so again this may be something you look at improving yourself, but when using the tactic, not touching the instructions I have found to work perfectly well.
Winter Update Tweaks
You will also find below a few tweaks I have made to the tactic for one of my saves (with Norwich City since the Winter Update - 21.3.0). I have found with some saves the tactic worked perfectly on the 21.3.0 patch and with some others (including my Norwich Twitch save) that occasionally against certain teams the tactic may struggle on the new patch. The images below include 3 small changes I made to the tactic which counter acted the new patch and which you may find useful if the tactic doesn't work first time for you. They mainly focused on the line of engagement and two of the midfield roles:


How The Tactic Performed
Using this tactic at Atalanta in my personal offline save we managed to finish comfortably as winners of Serie A in what is now our third season. We finished the season up on 100 points, with 31 wins, 7 draws and 0 defeats after going unbeaten and actually breaking the Serie A record for games unbeaten now sitting currently on 62 games without defeat. In addition to this we also had the best attacks and defence in the league with 111 goals scored and only 21 conceded. Finally, using the tactic we also reached the Champions League Final sadly losing in ET to Man City and even had the golden boot winner in Musa Barrow scoring 41 goals in Serie A in only 35 games! On top of that with Musa Barrow, he even broke the Serie A record for goals in a season (originally held by Higuain at 36) and also broke the records for most player of the match awards and average rating while being used in this tactic. Don't get me wrong, Barrow is decent, but this tactic very much got the best out of him!





Below your also find the analyst stats for my Atalanta side including the very impressive goals per game ratio Atalanta had using the Unbreakable Diamond in Seria A. They were far and away the best offensively and were even more impressive It was also the case across both of my other saves with Liverpool & Norwich City (which I’ll come too shortly).




As of today (March 13th), I've just completed what is my final season at Atalanta and have now won a Domestic Treble as well, absolutely walking the league and cup. In Serie A, my Atalanta side managed to secure themselves 105 points, a Serie A record winning 34 of the 38 games as well and losing only 1 all season. On top of that the team also scored 114 goals over the 38 games meaning they had an average of exactly 3.00 GPG in the league, by far the highest of any team. You can all of this below and also Musa Barrow again managed another season with 40 league goals which is just crazy!




After the success with Atalanta, I then tested this out with Liverpool and have also been using at Norwich City on my Twitch stream. With Liverpool, I used them so I could test and see how a different side, arguably a league favourite would perform using this. You can see how the Liverpool side mainly lined up below:

Using this tactic, Liverpool won themselves a treble (or kind of a quadruple if you include the glorified friendly that is the Community Shield). Liverpool won themselves a Premier League, Champions League and League Cup. They also managed to reach the FA Cup Semi-Finals however were defeated by Wolves at this stage. The squad though not only performed well as a team, but individually, Mo Salah had possibly one of the best ever season performing at crazy good levels, scoring 63 goals over 58 games and even being awarded the 2020 World Player of the Year based on his crazy season. You can see quite how Liverpool got on in their competitions and the League below as well as Salah’s insane stats too:




Finally after Atalanta and Liverpool’s success we also come to Norwich City who I have been using in my Twitch Stream save. In my opinion they were arguably the most surprising and craziest ones from this simulation. We have a decent team 6 seasons on, but the team was only predicted to finish in the top 6, yet after 25 league games, we are not only top of the Premier League but also battering teams for fun in both the league & Europa League! Generally speaking, our Norwich side would line up something along these lines when using the tactic.

With this tactic, we sit top of the Prem with a 2 point lead over Manchester United and are 11 clear of 3rd placed Liverpool. On top of that we have both the best offence and defence in the league and in our 6 Europa League games played have a GD of 27! The side prior to this season has always been, but this year with this tactic being used, the side has exceeded even my own wildest expectation. You can see exactly how we are doing in the league and competitions we are in below:


Also as of Today (Friday 12/02/2021), an update on the Norwich save is that we have now just finished the season in question mentioned above and come away as Premier League Champions, as well as treble winners winning also the FA Cup and Europa League. Its astonishing how well this tactic did considering Norwich were a decent side yes, but only predicted 5th in the Prem and instead finished 10 clear of Manchester United with 92 points! The title victories you can see below:



Finally a user who had been using the tactic in their own playthrough as well recently provided me with the following screenshot of their Fulham side at the end of season 1 in game! After using the tactic despite being Fulham's first year back in the Prem, they managed to finish 4th in the Premier League on 68 points, scoring 70 goals and conceding 53 meaning they earnt themselves Champions League football year 1, despite being one of the poorest sides in the Prem! Check out the league table below:

Overall that is how the tactic itself functions and across each team I used it with, it functioned very well allowing teams to either totally outperform expectations or to dominate the other teams around them and just outscore them wherever possible!
Please do feel free to download the tactic via the link and I hope you get a lot of good fun and enjoyment out of this tactic on FM!
Finally, as mentioned above with using this tactic you can also find me over on Twitch where I currently am using this tactic with my Norwich City save. I usually stream 3 times a week, normally Tuesday, Thursday and Saturday so if you like FM21, why not come join us via the link below and drop a follow on the channel.
