I didn't say I want him, and there are still plenty of CFC fans that don't want any part of Rooney. In fact, I'd have definitely taken Falcao and even Cavani over Wayne, but that's out of the question now.
I do believe though, that Rooney is still capable of playing his best under the right circumstances. I don't know what exactly happened with him at United, but the fact is, he's only 27 and, if fully motivated and fit, there's no doubt he'll be able to do well, especially in his preferred position. I think, Jose may be able to get him going and is a strong enough personality to keep him in line, within reason, of course. This is a World Cup season, Rooney wants to play regularly and get back to his best and perhaps he decided he needs to move to achieve that goal.
I personally believe he decided to leave some time ago and both Moyes' comments and Rooney's camp reaction are just details of the long protracted transfer saga, where both sides are trying to put themselves in a more advantageous position while slowly heading for an inevitable outcome of Rooney leaving the club.
