I'm not so sure with countering 4-1-2-1-2 wide diamond with 3-5-2 flat.
Tonight, I have a league game against that formation and first I thought about using 3-5-2 flat. But my worries are, what if the enemy uses motivated wings? In this case, he would outnumber my defensive players with his offensive players.
With my theoretical approach, I think that a 4-1-4-1 with four motivated wing players should be more effective against the wide diamond and less risky than the 3-5-2 flat.

Opinions?
