I think Ronaldo's staying this summer.
Ferguson said he only expects to sign one player, and since he made it clear at the start of the transfer window that he wanted a #9 striker that wouldn't make sense if Ronnie was leaving as well.
And the English newspapers are suggesting Ronaldo is unhappy with Real's behaviour as well so he's choosing to stay
I'm hoping it's true, although for how long it'd put off his desire to move only he knows...
