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'd rather lose an argument than get into a long discussion in order to win it.

I only ever run when there's some point to it - say, if it's in a game of tennis.

When one gets beaten by somebody better, one has to know how to lose with humility. Sure, I could have served better. Sure, I could have hit my forehand harder. But the truth was this was like an avalanche, and there was no way to stop it.

I'm delighted and feel incredibly happy with what have been an amazing two months.

Always I believe that I can play better. But I am happy.

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.
