I am very lucky because when I come back home, I have a completely normal life. I can relax, playing golf, fishing - doing what I want. I know when I finish a tournament, I am going to relax at home.

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.

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.

Two weeks ago, I was in a fantastic situation, winning at Roland Garros. Now, losing in the first round, it's tough. The tour continues. Life continues. This is a sport of victories, not a sport of losses. Nobody remembers the losses. I don't want to remember the loss.

All sports are continuously developing, but what they all have in common is that the speed is increasing. That's also true of tennis; the ball is getting faster and faster.

Today people hit the ball with much more strength. Almost every player is capable of playing a winning stroke from any position. This means the balls arrive more quickly. If you want to reach them, you have to slow down from a high speed or suddenly change direction. These are moments when you can injure yourself, and that's what wears us out.

I will work day after day like I did my whole life ... I'm not going to change anything.
