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.

Barcelona, the tournament is, for all the Spanish players, an amazing event. I think is one of the top events on tour because is a historic event with a lot of tradition. A lot of years of the tournament, a lot of great players have been playing there. And it's in a real tennis club.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.

I would like to believe there is a God, but I think it is better to say I'm not sure there is a God and live your life with kindness and respect for people than to say I know there is a God and then do bad things.

For me, it is important to win titles and for that I need to work hard, stay healthy and be able to compete. The rest, I always say, it comes.

If somebody says I am better than Roger, I think this person doesn't know anything about tennis.

It's hard to say, 'I don't believe in God.' I would love to know if God exists. But it's a very difficult thing for me to believe.
