I have an office in Argentina, I go there every day, so I work.

It was very hard for me to practice and enjoy my tennis, and I didn't know the why, so I worked with psychologists to try and see what was happening. They pushed me really hard.

Now I have the bravery to do fine things.

I loved to play, I was competitive, I wanted to win, that was all I knew. In the first few years tennis is a game. Later, it becomes a job.

I didn't know what was going through my mind.

I think in the lifetime of a tennis player there are many times where you feel that tremendous confidence.

I can't laugh, be happy, present myself at any prize and also win on the centre court.
