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.

I let the evening unfold. I'm the sort of guy who likes to sit in the chair and look at the wine glass.

I hope so. God, I've practiced so much that I you don't want to be worse five years later. I feel I have a great game today. I know how hard it is to pull off those great shots, and I know how easy it is to miss, so I'm more aware of these things. But I'm so happy I'm at the age I am right now because I had such a great run and I know there's still more possible.

When they [court announcers] say, 'This is the world No. 2,' it just doesn't sound right to me because either I'm No. 1 or I'm a grand slam champion. I'm not world No. 2. I just don't like the ring of it when I'm introduced on court because I've been up there for so, so long.

Watching a movie a couple of weeks ago. An American movie. I can't remember the name, but it wasn't even a sad movie. It caught me off guard. I was on an airplane.

One or two years ago, I didn't know who I was on court and I used to swear a lot. But now I've learned how to cope and can therefore win 10 matches in a row. I want to be remembered as a good player rather than an idiot on court.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.
