I've probably put up with more criticism than a lot of people out there. At the end of the day, you block out everything, especially with your personal life.

Tennis players go into a press conference, and almost every one of them is the same. We do very little differently on a day-to-day basis.

I'd much rather win in three or four sets than go the distance all the time. I seem to put everyone through the wringer quite a bit.

I have sometimes played my best Davis Cup matches away from home when you stay in the moment a bit more. But it is tough when half the crowd are spitting on you.

Grand Slams are different. If you can get through a few matches, the draw opens up and you get confident. You just need a little bit of luck early, you get through those opening matches and you never know what could happen.

I'm one injury away from hanging up the racket at any time.

Everyone has to call 'time' at some stage.
