Stick Diego in either Inter or AC this season and he would of shown alot more than both Ronaldinho and Sneijder has done. Diego is unfortuantly in a suffering Juventus team. The player who rivals him in sheer quality is Cassano.
I'm not saying he's a bad player. Actually, he's one of the few players I think should keep be proud over his performances this season but he's not more talented than Ronaldinho.
The problem is that some people (some sites are included also) count as an assist even if the player touches the ball without any intention to pass it to the scorer.
