I cannot guarantee anything.

I never wanted to change countries; it's something that is part of me.

I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

Even though now I'm pretty popular in my country and tennis is the No. 1 sport, and I'm very flattered that the people recognise me and come up and give me compliments, I'm more a person who likes to have privacy and peace.

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.

My priority, the most important thing in my life is my family, my wife and my son.

You can not say you're unhappy because you have to travel, have to play this tournament, having to play sports ... You can't because you chose to play it and you love it. I'm tremendously grateful for the support I have received from my family and the close ones.
