Certainly I would like to have some of the qualities of other players and obviously from Roger Federer. But believe me, there are plenty of other abilities that are important, particularly mindset and strength.

My motivation and aspiration is the same, being number one or being number five. So that's the truth. And my goal is the same - it's to always be happy playing, it's to enjoy the game and improve always.

The glory is being happy. The glory is not winning here or winning there. The glory is enjoying practicing, enjoy every day, enjoying to work hard, trying to be a better player than before.

I am lucky because my family are comfortably off. My father has his own glass business.

I am not the most courageous guy in the world outside of the court.

There is some moments on the career of everyone that are important ones. Is obvious that first title on clay makes a big difference. After that, I was confident enough to keep going, winning in Barcelona, in Rome, then in Roland Garros.

Tennis is a hard sport. There is a lot of competition all year and you play alone.
