I think it's just me, im doing the objectives at the minute so it's not the teamTry changing your team completely. I couldn’t buy a win until I started the icon objectives. Found a great cheap Italian team with a front 3 of Gervinho, Lasagna and Cuadrado with Bonaventura, Pjanic and Lucas Leiva in midfield. Rattled the objective off in 4 matches with 3 wins and a draw, beating a stacked team with 2 icons up front 3-0 in the process.
They played brilliantly, making perfect runs and linking up well. Maybe it was my turn to get lucky but my point is to try different teams, sometimes they just click to your playing style.
