I was incredibly competitive, growing up with two brothers; we'd argue and play against each other in the garden continuously. If we have a competition, I want to beat them.

Playing week in, week out in the Premier League is massive. You're coming across the best players in the world in probably the best league in the world.

It drives you on all season when you see the end rewards, first and foremost for your club, and then, obviously, to play at a World Cup is the pinnacle of anybody's career.

I don't often score goals that aren't with my head!

I always thought I wanted to play professionally, and I always knew that to do that I'd have to make a lot of sacrifices. I made sacrifices by leaving Argentina, leaving my family to start a new life. I changed my friends, my people. Everything. But everything I did, I did for football, to achieve my dream.

What people see the first family do has an effect. And from a slightly different aspect, I think that family living in the White House is going to have a profound effect on many Americans.

My mother had abandoned the family, so grandmother raised me. And she was instrumental in that she taught me that the world is a glorious place. She taught me to embrace humanity. And she'd say there's never an excuse for joy. And to be thankful.

My family didn't have money, and I think it made me fearless. I'm willing to try everything and not be afraid because what's the worst that can be happen? It might not work out, but I can't be worse off than when I was a kid.
