I'm a big fan of High pressure & Counter-Attack Football. I have created lot of tactics but have only ever kept them to myself. When I started playing FM 13, I found it hard to win games. I used a lot of tactics from FM 12 but none worked so I thought I should do more work to analyse the game and how players pass/score and stuff like that.
I've been a Liverpool Fan since I learned about football. So i always start with Liverpool until I create a solid tactic before I use other teams and embark on other challenges.
First of all, I used two tactics:
1st: 4-3-3 (1-2-3-2-3)
2nd : 4-4-2
-Both tactics working like a charm, but I decided to use the first one.
I won't tell you what type of player this tactic need, I almost never do that. Just believe in your scouting ability :P. Look at player instructions, then find the best player you can to fill that position. For example, if the player required has to run a lot, you should look for players with high stamina, work rate, positioning, etc. In the end, you will find advice on what a player requires for each role and how to train them for that role in this guide made by RandydeB:
