I have two strikers and a midfield packed full of talent. One of my strikers has 33 goals and 24 assits, and my highest midfielder has 13 goals and 22 assits. No other player in my entire team has more than 5 assits. One of my Attacking midfielders has 17 goals 0 assits. He seems to score anything he hits from range. My other AM, has better stats, everything would seem better, but has 1 goals and 1 assits in 33 games.
I purely think some strikers may be brilliant in stats, but just cant handle it. Some players just dont work, so my advice is sell them on, and replace them.
