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 don't know how you can go through a four-hour match with Rafa and he never gets a time violation.

I'm at the top of my game so, when I win or lose, I don't freak out...I don't think we can call it a rivalry yet. There's just to many great players around.

Mentally, I'm not ever going to go away.

Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

I think it's very hard for coaches to work with me. They'll no doubt have a good CV afterwards, but at the same time they're under a lot of pressure.

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