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.

For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.

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.

I am decidedly unfriendly during a golf game, from the first hole to the last.

I always wanted to be honest with myself and to those who have had faith in me.

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

What distinguishes tennis is respect for one's opponent, one's conduct on the court.
