Chris Evert believes there are three players - Stefanos Tsitsipas, Alexander Zverev, and Dominic Thiem who can beat Rafael Nadal and Novak Djokovic at the French Open.
Nadal has singularly made Roland Garros the most unobtainable title in men's tennis over the last 15 years, while Novak Djokovic has been dominant just about everywhere else.
That has left few opportunities for the younger players to win majors, but Evert believes that could change here, with Tsitsipas looking particularly strong.
“It’s not a closed door that only the big three can win Grand Slams, for sure," Eurosport expert Evert said. "Other players have beaten them.
“I think Tsitsipas has come a long way this year, he has impressed me the most of all the next generation of players.
"He has impressed me not only with his game, but also with the aura he has around him. The mental strength he is showing, the calmness he is showing during the big points. I love the progression in his tennis.
“I’ve been very impressed with Sascha Zverev – when he’s serving well, he’s still really dangerous on any surface – it’s just a matter of getting that serve going for him.
“Dominic Thiem has reached the final of the French Open, after having a break hopefully he has re-charged his batteries.
“The three I’ve just mentioned are the top prospects because they’ve had wins over Nadal and Djokovic.
"It is getting closer and closer but the top two are still Nadal and Djokovic.”
“Again, if Zverev can just keep that first serve going, he moves well for a big guy, he has got weapons, he has impressed me a lot. And Thiem is the most consistent, solid guy.”
