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

I liked the Paul Ince and Roy Keane partnership Manchester United had. They would have been my team had I moved to England.

If he continues like this then I think Messi will be the best player in the history of football.

The way I see it, Messi is the best player in history. He is the one who changes the course of games; he's the best. There is no comparison in my view; he's the world number one and by a margin.

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.

I'd love to play at Wembley. It's special for Barça - and for everyone in football.

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