Yeah, I get that, and I'm also not saying he was amazing for us. His main problem though was that he wasn't Raul!
His stats at Fiorentina are also interesting

He scored four in the equivalent of nine 90 minutes last season He clearly just didn't fit the profile of what they were looking for. The one run of games he actually had for Fiorentina, he played with Ribery behind him and he did alright. I watched a game and he was fairly good.
this season has had almost no minutes at all. Maybe he's a shit trainer? I don't know. I think he can score goals, he defends well from the front but the bits inbetween, not so strong which is maybe what people are looking from him.
