He's very, very good. But not quite as good as Ronaldo and Scholes this season. I feel its more:
Ronaldo
Scholes
And then I can't choose between Saha (Good goals, some important for wins) Evra (Great wing play, not quite so good defensively but still pretty good) - G. Neville (pushing the team forwards) - Giggs (Great form at the beginning of the season, not so good now) Rio and Vidic (Its hard to choose between them as they both have made each other play better and who is to say who is more important of the two) - Van Der Saar (Not so much to do this season, but when hes had to do it, chances are he's passed each test with flying colours)
And after everyone else, then comes Carrick... Who has done okay. And recently looked like finding his spurs form. But more to come.
