I've always been aware that the image you patiently construct for an entire career can be ruined in a minute. It scares you a bit, but that's the way things are.

I have a very strong opinion. I'm absolutely against it. I'm against the challenge system. I'm for the way it is right now. Don't change that.

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 did all the right things in so many tournaments. But like I said, sometimes in sports it just goes the other way. Maybe you've already won so much that it evens it out a bit sometimes. I don't know.

Oh, my God, I don't think any player can look forward to or expect to a career of so many Grand Slam wins or title wins or being so long at the top of the game.

The serve, I think, is the most difficult, you know, in terms of coordination, because you got the two arms going, and you got to toss it up at the right time so.

Winning or losing, it's always something special and something you'll remember, even more so when the match was as dramatic as it was today. It's even more memorable when I see my kids there with my wife and everything. That's what touched me the most, to be quite honest. The disappointment of the match itself went pretty quickly.
