Ronaldo isn't going anywhere this summer. He has a contract until 2010 and the Glazers would never endorse it according to the club's CFO.(BBC report)
It makes me laugh when I hear this kind of thing. If Ronaldo is happy at OT and wants to carry on there, then fine. No point in selling one good player to sign another who may not be as good anyway.
But if the guy wants to go, and according to the Spanish press he does, then he will almost certainly be sold.
What's the point in having a discontented player underperforming and rapidly losing his value when you could sell him for a healthy sum and replace him or do something else with the cash?
