I began as a striker, then became a holding midfielder, and now I'm a centre-half. I've done everything except play in goal.
Maybe apart from the World Cup, the Champions League is one of the most important trophies in the world of football.
English football is very physical, much more so than Spanish football - I felt it in the first match.
I've spent my whole life playing football. My father didn't want me to play rugby because he felt it was very hard on the body, so at school, I was encouraged to play football, and that's where everything started.
Every training session you take part in, you have to work very hard and train hard because there is no other way to get where you want to be - it's not a secret and not a magic formula - just hard work and application.
I can still improve, and that's what I try to do every day and train strong, and as I said, I try to improve every day and make myself a better player, and that's what I am trying to do.
