Was ignoring this thread...because know naff all about current players or tennis in general.
But then I remembered I had a curious thing about Justin Henin a few years ago. Looking at her before play...in still photos, no arousal at all. But I watched her in a match..effectively by accident...and something about the way she moved about the court really did it for me. Always tried to watch her matches after that...and first reaction was no fluke.
