I don't know that Rio's got 5 solid years left in him. Anyone who's watched United closely over the years has seen that despite his generally excellent form, an increasingly large numbers of mistakes and patches of lazy play have snuck in. I'm certainly not likening Rio to Mikael Silvestre, but I'm a bit more concerned about a long term cover for Gary Neville than I am Rio.
That being said, I'm sure United will get Rio to agree to a sort of rolling one year contract along the lines of those we've seen them issue to senior players before. And I'll be all the happier for it.
