My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.

The confidence is there, the game is there, but physically you can't fight nature sometimes. You can't do much about it.

People look up to me as somebody who is able to switch the image of our country from negative to positive.

I think if you do not enjoy your time, your life, if you do not live intensely and do not spend time with your family, in one way or another it will be reflected in your career.

Messi is the best player on the planet and he keeps on improving at Barça, now the best team in the world. What Messi does on and off the pitch is an inspiration for children who dream of becoming a footballer.

The fact that nobody played tennis in my family and you'd say by chance they make three tennis courts in front of the restaurant that my family owned when I was 4, I think that's a destiny. That's kind of life circumstances that kind of come together for you to become who you want to become.

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.
