I use Herbalife products on and off the field for energy and focus. That way I can play my best game

Goals are only important if they win games

I never think about the play or visualize anything. I do what comes to me at that moment. Instinct. It has always been that way.

Ronaldo was my hero. I loved watching players like Zidane, Ronaldinho and Rivaldo, but Ronaldo was the best striker I've ever seen. He was so fast he could score from nothing and could shoot the ball better than anyone I've ever seen.

I repeat what I always say: I want the best for Argentina in every way. I never try to make trouble for anybody.

Ronaldinho was responsible for the change in Barça. It was a bad time and the change that came about with his arrival was amazing. In the first year, he didn't win anything but people fell in love with him. Then the trophies started coming and he made all those people happy. Barça should always be grateful for everything he did.

I still have a lot of room for improvement. For example, I want to shoot equally well with both feet.
