No one has nicer teeth than me. Why would anyone laugh at my lovely teeth?

Ashley Cole is a fantastic defender. I have seen him keep the best players in the world quiet.

My best has to be for Barcelona against Villarreal in 2006 - that is the one I am asked most about, and it is the one I am most proud of. Xavi chipped the ball to me, I chested it down, twisted and hit an overhead kick. It was the final goal in a 4-0 win.

Brazil goes into every World Cup expecting to win - so when it is in Brazil it is expected even more. You can't understand what the World Cup means to our country.

My game is based on improvisation. Often a forward does not have the time to think too much. You have a second, rarely more, to decide whether to dribble, shoot or pass to the right or left. It is instinct that gives the orders.

I still have a video of my father, which I watch before every game I play for Brazil. It gives me strength, makes me determined.

When I got to the senior national team, there was another Ronaldo, so they started calling me Ronaldinho because I was younger.
