My father never talked about the sacrifices that the family made for me.

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.

Honestly, I'm not a big fan of baseball.

My strokes just weren't there.

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

I'm very fortunate to have the support of the people around me, I feel happy because my wife helps me and people who are close.

It's always easier if you have the support of your family, if you're not alone. I came from a country that has been through a lot of troubles in the last 20 to 30 years, but we have been through them together.
