Maybe one small regret is that I never got to play with Paul Scholes - but I was never going to leave Barcelona and he was never going to leave Manchester United.

In the last 15 to 20 years the best central midfielder that I have seen - the most complete - is SCHOLES

Some teams can't or don't pass the ball. What are you playing for? What's the point? That's not football. Combine, pass, play. That's football - for me, at least.

The atmosphere generated by the fans in Celtic's stadium for our visit was the most impressive I've ever witnessed. The grounds of Liverpool and Manchester United are good and the hostile feeling of playing against Real Madrid in the Bernabeu is also excellent, but the atmosphere against Celtic was the best.

Leo [Messi] is the best player of all time - better than Pele, Maradona or Cruyff. There have been some great teams in history - Pele's Brazil, Cruyff's Ajax, Sacchi's Milan - but in the past 20 years this Barcelona team is the best.

There are two types of football - there's physical football and football talent.

To me Paul is a role model. He is the best midfielder I've seen in the last 15 or 20 years.
