Look at the screenshot, if its consider like 4-1-3-2 wide then one of my academy team win twice using 3-1-3-2wam-1, which I never thought against that wide formation but it's work, q me 35.9 and he 33.1
I think I read in this forum someone says, this season 3-1 def working good, and I believe he is right. Every season looks like all known counter formation wont working well.
