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

If you're playing for five hours you don't want to score goals all the time and I loved dribbling. I could score a goal, but I preferred to dribble.

My only concern is playing. Everything else, my family looks after. In our house, everyone has a job, and my job in our house is to play football.

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.

To its great credit, Wimbledon has been a leader in bringing about change and improvement in the sport.

I worked in a gym. I was a trainer. I did all the crappy ex-football-player jobs.

Retiring from international football was a personal decision, and I was very sure about what I was doing. I played for my country for more than ten years, and there were highs and lows. It was a fantastic experience, though, and the most wonderful thing is that it ended well.

I have a Ph.D. in philosophy and sports science. At 14, I went through this really tough Soviet training system. A lot of my roommates got psychologically broken or physically injured. Either you came through, or you were out. I made my Ph.D. work in the field of young athletes aged 14-19 because at this age any human is changing.
