Be patient, tactic need some weeks to be known.
When u play vs biggest team try to change your complete wingbacks to fullbacks/support. Also try to play wider, and use always pressing on all offensive opponents.
Both false nine need to be fast and/or good at dribble. Last striker need to be a good scorer. If you see he miss 3 great chances in a game, switch him with another strikers, its not his day and he wont score.
