Seven-time Grand Slam champion Justine Henin has insisted that Serena Williams remains untouchable in women's tennis following the American's triumph at the French Open.
The world number one clinched the 20th Grand Slam of her career on Saturday thanks to a dramatic three-set victory over Lucie Safarova at Roland Garros.
Williams, who was suffering from illness before and during the final, is now just two majors behind Steffi Graf's Open Era record of 22.
"Even sick, she remains the best," Henin is quoted as saying by BBC Sport. "I don't see a girl, or four or five girls that can push her. In a match for sure she can be dominated, but over a whole year she's still the best player in the world.
"When she wants to win something she usually has the capacity to do it. I'm not very concerned about the fact that she can be at the top of the game for the next two or three years."
Henin won the French Open on four occasions before retiring for a second time in 2011.
