I'm not the best player in the history of tennis. I think I'm amongst the best. That's true. That's enough for me.

My motivation is tomorrow, just one day at a time, right?

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.

I always work with a goal - and the goal is to improve as a player and a person. That, finally, is the most important thing of all.

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.

I like fishing. Not actual fishing - I like the peace and quiet of being at sea. It's different.

Hard courts are very negative for the body. I know the sport is a business and creating these courts is easier than clay or grass, but I am 100 per cent sure it is wrong.
