Hi Wraga,
Firstly the following is just a suggestion. There is no right or wrong in tactics, but more about if it is a more suitable and effective counter with a best estimate of what the opponent would do (eg. 4-3w-3w would suggest opponents playing via flank, and if that opponent manager somehow choose to play via middle then things could be unpredictable).
With your scenario, the first thing I would do differently is to overload opposition DMC area(without DMC is as good as it gets) instead of both flanks with fullbacks. Second main concern is both opposition best ST & MC is 1* above your team’s, so both areas require at least +1 player to offset the quality disadvantage, hence 3 defenders and 4 midfielders is a default to have a more controlled match (gung-ho aggressive setup to win by outscoring would mean win-1-lose-1, and that would lose all trophies easily). DMC to counter AMC is spot on there, so the default formation would be 3-1-4 up till midfield. Game control-wise would be playing a AMC + ST.
To utilise the most of AMC area, playing 1 AMC + 1 ST in the conventional positions may not be the best option. Considering the opponent has 2 DCs, our ST should always move away from them to score easier, if possible. MC quality difference is still a concern even with a 1-man advantage, so the better solution would be moving MCs back a little (to help DMC a bit), then pull AMC as back as possible (creating a 3v1 triangle vs opposition 3 midfielders), and finally move ST as back as possible too. Central AMC area should be where the game is won (opposition has ‘wasted’ 2 players with wide defenders irrelevant for the match setup in this way).
