Most would have known half way through last season that it was more than possible that he'd want to leave this summer. It's not a huge surprise.
As yet he's not done a great deal wrong though. He come out with the whole media line to begin with and it's easy to understand why. By putting it on the media he could ask for a move without upsetting our fans. It's subsequently (although I'm not sure he's actually said it publicly) come out that he wants to leave because of CL football which most people already knew was the real reason. As above, it's not a surprise nor is it unreasonable of him to want to play in the CL.
He turned up for pre-season training as expected, trained and played - even if he did have a face like a smacked arse, he still played in the same way he always does. There's been no striking, suspect injuries or even a transfer request like many expected him to do and what a lot of other players have done in the past.
