The women's clash that everyone has been talking about arrives on Tuesday when defending champion Justine Henin takes on Serena Williams in the quarter-finals.
Here's what BBCi commentator Sam Smith makes of the biggest match of the tournament so far:
"I don't think there's any doubt that these are the best two players in the world, especially on red clay, and it will be a brute of a match.
"But while these two are the best out there they are being caught quickly by some of the others and I don't think the winner is guaranteed to go on and take the title - there are too many other players playing well.
"I saw Kuznetsova playing Peer and you had to be there to believe the power with which she was hitting her forehand, and Jankovic is also playing well, as are Vaidisova and Ivanovic. Then there's Sharapova, although she's a long way away on this surface.
"Henin has played well so far but has a had a bit of trouble finishing off her matches, while Serena's not been anywhere near her best yet and she'll need to be nearer that level if she's to beat Henin.
"The last time they met was in Miami in April and Serena won after losing the first set 6-0 and saving match points. I was surprised afterwards because Henin reacted like she didn't fully expect to win the match.
"The word on the circuit I hear is that she really doesn't like playing Serena, she doesn't relish the power, and I'm not sure if she really believes she can beat her.
"One factor that could come into play is the crowd. The last time Henin and Serena met at the French Open was an acrimonious affair when the Belgian won the 2003 semi-final and Serena left the court in tears to the sound of Parisians booing.
"And I think if Serena's not careful it could happen again. The Paris crowd love Henin because she's almost French - she's a French speaker and has done so well here.
"Serena has not exactly gone out of her way here to charm the crowd and if they get on her back again it could be difficult for her.
"They haven't had much to get stuck into yet but they're itching to get involved and they can be like a third player out there sometimes.
"But as for a quarter-final prediction - if Henin is going to win it has to be in two sets, otherwise it's Serena's match."
