Problem with Diego is that he's strictly an attacking mid. Can't play behind striker. Can't play wide. Can't play deep. So you have to build a formation for him but he's not good enough to warrant that.
Great post.
I always liked Diego. He's got skills, he's got heart, he's got a winning mentality. Not like the majority of Brazilian footballers who eat shit for lunch. He's just not good enough to carry a team. And his position - classic central AMF - is just not used in Europe anymore. And he was very unlucky to be in that team.
Honestly, as of today I think he would fit well in the squad. I think he works for the team and helps marking enough. He would be a very good option in the squad, but it would be very hard to enter the starting team - he would fight Marchisio for the position.
And he isn't quick enough to play as an SS. But in Marchisio's position he'd do well.
Wish the best of luck to him.
This reminds me of Melo. He is one of the most athletic and skilled all around mids I've ever seen. To bad he's retarded and a loser. Vidal is what he'd have been with a proper brain.
