I don't think he has conducted himself well at all. I like his outspoken personality, his ability to articulate his point of view and the fact he wont hold back what he thinks. I like this side of his character a lot, but I honestly think he's a lot more cynical than people make him out to be.
I don't think he loves the club or the fans the way he says he does. This whole Twitter scenario has been manufactured from the start in tandem with his agent, in order to publicise himself and get the fans on side. I don't think he's entirely truthful either. He said he wasn't offered a contract? I'm convinced that he was, and probably one that matched his value as a player too. The whole thing has been about making him the centre of attention, even organising Sky cameras to travel round with him when he was going to talk to QPR? Fucking hell, man.
Good luck to him, good player and will be a miss short-term without a doubt. But his reputation far exceeds his actual ability level.
