The toughest opponents for me are the defenders who are tough in the way they play - where you can't see a way through.

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.

It is not just about the money, it is about what you achieve on the pitch.

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

I am what I am thanks to my mother, my father, my brother, my sister... because they have given me everything. The education I have is thanks to them.

Even from when Lionel Messi was very young I could see that he was a great player. A lot of people spoke about him, and then when I saw him myself for the first time I could see the amazing quality that he had. I didn't teach him anything - he had enough quality himself.

God gives gifts to everyone, some can write, some can dance. He gave me the skill to play football and I am making the most of it.
