He seems like someone who could be taken to the next level at Chelsea, at Arsenal i always get the feeling with him that he doesnt take things too seriously, he seems too laid back with all his mates at Arsenal, he is surrounded by people like Gibbs, Walcott, Welbeck, Wishere, Ramsey ect, i get the feeling that he is probably someone who gets up in the morning looking forward to have a laugh with his mates at training rather then actually focussing on improvng. if he came here it would be completely different, i think his mentality would be different, and he would mature here into a top class player.
