I certainly don't lose any sleep if I lose a tennis match.

People may say I developed an iron will, but what really happened is that I made myself much fitter. I think an iron will is always supported by fitness.

I am not playing Wimbledon because I am allergic to grass.

Because in order to beat Jimmy, I had to get around the ball a little bit quicker so I wasn't always on defensive and catching the ball on last stride, that I had little more time. Once I was able to get little bit quicker, then it has helped me a lot.

But to be fair, if you take players from my era to now, the game has changed and the players have many more shots. They use them differently than we did. The speed of the game has changed.

When I lose, it doesn't just go to my head; it goes to my heart too. If you're at all in the match, if you love to play and ein, it must go to your heart.

Once you win, you have no doubt that you can win. So you have gone through it once, and you can do it again.
