Watch all the action from the 2021 French Open live on Eurosport, eurosport.co.uk and the Eurosport app with 13-time champion Rafael Nadal eyeing a remarkable 14th title and 2020 Roland Garros sensation Iga Swiatek aiming to replicate her stunning triumph.
Serena has 'excellent' chance of French Open glory - Wilander
Very sporting - Gauff gives Brady hug and claps her off court after injury ends match
As Eurosport expert Mats Wilander noted after her win over Danielle Collins, the draw has opened up very nicely indeed for Serena Williams. She has a great opportunity to keep moving into the quarter-finals if she can overcome Elena Rybakina. The 21st seed Rybakina will throw everything she can at Williams and it could be a great match.
On the men's side, who has not enjoyed seeing Kei Nishikori back fit and firing in this tournament? The popular Japanese star will be hoping to give sixth seed Alexander Zverev a serious challenge in their fourth-round clash.
Anastasia Pavlyuchenkova was hugely impressive in downing third seed Aryna Sabalenka in the third round and she could well spring another upset against Victoria Azarenka in the first match up on Court Philippe Chatrier.
Pavlyuchenkova could hardly have made a bigger statement in bagelling the much-fancied Sabalenka to close out that match in the deciding set and the 15th seed Azarenka will have to be at her best to progress.
'Not many people know this' - Nadal stat 'vital' behind success, says Evert
Cameron Norrie may have lost out to Rafael Nadal on Saturday to end British interest in the singles draws, but there are still plenty of other representatives at Roland Garros.
Neal Skupski and Joe Salisbury are both in mixed doubles quarter-final action; Jordanne Whiley features in the women's wheelchair doubles semi-finals; Andy Lapthorne is in the men's wheelchair quad singles third-place match and men's wheelchair quad doubles final; and Alfie Hewett and Gordon Reid are in the men's wheelchair doubles final.
Elena Rybakina will have to produce the performance of her life to overcome Serena Williams but it is a wonderful opportunity for the 21 year old to make a huge statement on the big stage.
Another name that casual fans may not be too aware of is Alejandro Davidovich Fokina and the 22 year old Spaniard has every chance of reaching the quarter-finals. He takes on Federico Delbonis.
