He played well in the last match, not his fault the others can't finish in that game. Against Atletico he suffered as he was out of position. The game where he was in midfield against Real was his only bad game where you can blame him. He can't play well all the time though. You guys standards are crazy where if player doesn't perform in every big match they are thrown out of the club.
He is a great player but not being used right at all. I know I said it might be a good idea to sell him but not because I think he's shit like everyone else here, but because managers are not finding a proper role for him.
If you think he's shit you need your head examined. Also the "slow" thing is the dumbest thing I ever heard. He's not even our slowest mid and mids aren't meant to be quick anyway. He's about positioning, vision and passing.
