your 2 dc can do nothing against 3 st you have a dmc and he dont use amc . you need to use 3N-2(DMR DML)-2-2-1 . ml mr blockrd by your dmr and dml. dont need to much players in the center and you can take advantage from flanks . all pitch trought flanks long pass force counter if he is better or equal . but if your tatic lose against 4-1-4-1 i dont have any ideas :s
