Former world No.1 John McEnroe won Wimbledon three times
McEnroe, 58, emphasized that Williams was “an incredible player” and the “best female player ever — no question.”
Neither did he rule out that a female player would one day be able to outshine the world’s best male players, saying: “Maybe at some point a women’s tennis player can be better than anybody.
“I just haven’t seen it in any other sport, and I haven’t seen it in tennis. I suppose anything’s possible at some stage.”
Ranked 700 in the world on the men’s Tour is Issam Haitham Taweel of Egypt, a 27-year-old with no career titles, while Russia’s Dmitry Tursunov is a place below him in the rankings.
Tursunov, 34, told the BBC that he hoped that he would beat Williams were they to ever play each other.
