I figure out something yesterday. Ted is right, scoring goals seem to be harder against weak teams this season, so i change formation to something very offensive, 4 3 1 2 and also tried 4 2 2 2, both with strong MCs and AML, no DMC, offensive, counter attack, normal tackle

Won 7-0, 11-0 vs low Q team and 4-0 vs equal team today.

Then i check league of my lvl 7-8 friend and top manager also ALL have something with 4 defender and atleast 1 ST + 2 AMC/AML
