I think the Graf v Navratilova rivalry is my all-time favourite. Steffi always said that Martina was the true measure of her game and often called her the toughest opponent she ever faced in her career, although I don't know if she still says that. There was an interview some years ago where, for the first time ever, Graf called Seles her toughest opponent. In any case it'd be a tossup between those two southpaws, I think, with Navratilova's classic left-handed serve-and-volley being more of a challenge for Graf's style.That’s my favorite Graf/Martina match ever. Thank you for posting.
Serena concentrated far more on slams than any other player in history.Thanks ^^
Back to tennis, I was a bit surprised this week to hear that Serena played "only" her 1000th match, she turned pro (end of) 1995 ?!! Federer who has the same age, and turned pro in1998 has played more than 1500 matches.
Steffi had more than 1000 before being 30.
