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

You know as a player that you won’t have many opportunities to play in World Cups - so you have to take them when you can.

Goals are only important if they win games

I know how important it is to have a helping hand. In my childhood I had difficult times because of hormonal problems. If I hadn't had support, I wouldn't have been able to fulfill my dreams.

I never had any problems with my height. I was always the smallest kid, at school and in my teams.

Argentina is my country, my family, my way of expressing myself. I would trade all of my records for the World Cup trophy.

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