For 2 weeks now all formations that have 4-4-2 are creating a lot of problems.

Been playing 4-5-1V or 4w-3n-2aml/amr-1. The difference is huge between me and them but they score goals. I barely win the matches and now ... 1/4 CUP i was matched against a 4-4-2 17*, me 20*.
May tactics are normal/attacking, down the flanks, whole pitch, normal takl, zonal, no counter with offside trap.

What should i do ? trust the old formation or play a 4-4-2 ?

Thanks
