Yeah, because putting on a good performance in the World Cup final against the World #1 and European Champions and favorites in everybody's mind (including most realistic Dutch people) doesn't entail any pressure.
Yes there would of been an immense ammount of pressure playing in such a massive game, but having that amount of pressure every week playing for the biggest club in the World in the best league in the World, where every little error or mistake is scrutinised to the nth degree, now to cope with that takes a very special player. And I'm not saying he couldn't cope with that, I'm just saying it's a big leap from Ajax to Man United, the Dutch premier division isn't exactly amongst Europe's elite is it?
Also on another note, I was wondering why United don't go for Kasper Schmeichel? Every time I have seen him play he puts in a decent performance, he is young and I'm sure United would be his dream move. I wonder if he is on Fergie's radar at all?
