For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

I am thinking more and more about what I want to and can do after my days as an active athlete. Thoughts like family and marriage also cross my mind more and more often.

The week before the (US Open) I gave a few interviews for CNN, USA Network, New York Times, USA Today and Sports Illustrated which had been arranged beforehand. The reason for giving these interviews is not only because working with the media is just part of the job, it is much more my desire to contribute to the promotion of tennis in the U.S.

For me, I'm in the driver's seat; I'm No. 1 in the world. I've won the last couple of meetings, and I've won the big tournaments lately. Whoever comes, I'll try to beat him. But it's almost up to me to decide who's my rival, isn't it?

I can't stay No. 1 for fifty years, you know. We'll see what happens.
