Italy World Cup winner Marcello Lippi admits he's a big fan of Manchester United ace Cristiano Ronaldo.

Lippi said: "It's difficult to imagine he can improve considering the level he has reached.

"You mustn't forget that he does everything at supersonic pace so it's natural to make some mistakes when you play at that speed.

"Maybe if he slows down his way of playing a bit he could reduce his margin of mistakes.

"But he doesn't have to do it because his major quality is to do great things at great pace."
