my team can not score many goals

[Wiesse]

hello,

How it come that my team not score more than 2 goals in official games. I have bought new players and i trie to find out which formation fits the best with my team. Last season i played 3-5-2 v style with good ending. This season I started with it but my team has trouble 2 score. I switched 2 4-1-2-1-2 narrow diamond but even then my team have trouble 2 score. i win matches with 1-0 or 2-0 or a draw. my team quality is the best from all.

anyone suggestions?
