Try attacking more and to have a plan on how you are going to score your goals. And who is going to score. If you have a single deep lying forward (DLF, PF), you need your AM or Wingers to be on attack. If you have a single striker on attacking forward duty (AF, P, TF) you want somebody to help him around the penalty box.
If your wingers are too slow they will never score against better opposition, so you might wanna change up who is gonna score your goals from game to game. The highlights are very good at showing why your tactics doesnt work and which players are being man marked out of the game.
