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.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.

A man who wins, is a man who thinks he can.

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.

The more I lose, the more they believe they can beat me. But believing is not enough, you still have to beat me.

With all the injury problems we have in men's tennis at the moment, I'm happy to still be standing.
