I want to reach absolute perfection. And I think I can reach it.

But the problem with coaching is that it is a full-time job. By that I mean for at least 40 weeks in a year you have to be with the player, either travelling or training. Right now I don't want to do that

But, then again, I had to stop because there was too much pain or too much trouble. After I retired I still had one more elbow surgery just to be able to do normal things

For the first couple of years I played really bad tennis. It was so bad that they booed me off the court

I want to reach absolute perfection. And I think I can reach it.

I always liked serve-and-volley players and big athletes

I was serving good but was returning especially well, which was a weakness in my game. So not only was I serving well, but I was also breaking these other guys, and they felt the pressure
