It's very fecking weird. As many have said he tried to leave during the summer, but by all accounts, no one came in for him, at least not seriously, or not with a bid (according to Andy Mitten who I'd class as highly reliable for United news*). If no one was after him then, this move is not going to make him a more attractive prospect to anyone, so surely, he is hurting his own chances at securing a move away? I can't see any top club coming in for him. I don't think any top club would have done based on the evidence of his performances this season, let alone this interview. It will be a move to a lesser league, or a leap towards semi-retirement, i.e., USA, China or Middle East.
I think Keane was quoted somewhere as saying he had some good offers to move but didn't. I'm sure Ronaldo may have been approached by agents, and likely spoke to clubs via agents, but unless a club comes forward and makes an offer for the player, either with a transfer fee or asking for him on a free, which there were no concrete reports of apart from Al Hilal (I think), then I'm inclined to believe Mitten, as I am sure he has better sources within the club who know what is happening from the clubs point of view.
