I dunno, he might turn out to be just what they need, a cog in the machine rather than a superstar. Fergie is a master of making a team more than a sum of its parts... he's made Darren Fletcher, Ji Sung Park and Wes Brown into part of the best team in the world (or maybe 2nd best!).
He just needs to make sure he gets other players in who will provide the goals that Ronaldo leaving will take away. I like Valencia though, sure he'll do well.
My thinking too. People will say he is Ronaldos replacement due to the position he plays although Man Utd will be looking elsewhere to replace the goals, assists and flair they have lost.
Mainly the centre of midfield were they were shown up by Barcelona last season.
