Personally, I think we could do with a proper left winger and allow Cazorla to play centrally, that's his best positon.
I don't agree. In terms of personal performance, Cazorla looks as if he is playing better in the middle, but the entire team gets worse. He ends up always looking like someone who is playing well in the midst of a non-functional team. When he plays out wide the whole team plays better and he just looks like one of the team. This is not a bad thing.
To me this is the Steven Gerrard syndrome. A player that always looks like he is a brilliant player surrounded by idiots. At some point you have to start thinking that they are looking like idiots because of, rather than in spite of him.
