My problem was that I have no AML - AMR so I bought ML and MR just for this game and still lost xD

I will keep ML and MR because that will become handy against strong 4-4-2 formations or If I want to play 4-1-4-1 as you said

Against 5 defenders is hard to score!
I never lost playing narrow diamond or 3n-1-2 formation, but always score was short (1-1, 1-0, 2-1 etc)
