This tournament could make him or break him. If he does well and scores goals, he can come back here and be fantastic, hitting the ground running and giving RM a hell of a selection headache.
On the other hand, if he doesn't do well, he could come back with his tail between his legs and end up being a burden and a massive distraction as his antics go from bad to worse. In which case a loan spell away would be best for all concerned.
He could be a Cantona for us, brilliant and enigmatic but he could just as likely be an also ran. A player with massive potential but who couldn't control himself and who wouldn't listen to advice or act on instructions. It looks like Mancini cuts him a hell of a lot of slack, but I hope he isn't giving him enough rope to hang himself.
