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.

But it's very difficult, I can tell you I played the Czech Open a few times and it's very difficult just to go on to a scene where the course is prepared differently when the greens are fast and he's not used to it and they're hard as a rock and he's not used to it.

My serve and my forehand I pretty much always had, but my backhand was a made backhand. I worked on it for years.

I have seriously thought about retiring, but that was on a good day. On a bad day I've thought about killing myself.

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.

You have to focus on the process. You cannot be glued to the results.

Too many people asking too many questions in tennis. Golf is better.
