Novak Djokovic had 100 million reasons to celebrate reaching the French Open quarter-finals on Wednesday as players made a mad dash to clear the fourth-round backlog created by the fickle Parisian weather.

The Serbian world number one became the first tennis player to bank $US100 million ($A138.3 million) in prize money after his 3-6 6-4 6-1 7-5 win over Spaniard Roberto Bautista Agut tipped him over the magic number.

However, the fourth-round winner’s cheque is a far cry from the real prize Djokovic has his eyes on this week.

What he desperately wants is to get his hands on the Musketeers’ Cup to complete his grand slam collection.

After winning a match that was originally scheduled for Monday, began on Tuesday and was finally completed on Wednesday, the 29-year-old will have to play four days in succession if he is to reach Sunday’s title showdown.

“I have the feeling I played three matches against him,” a grinning Djokovic told the crowd after donning a yellow rain hat during his victory speech.

“Yesterday the match was interrupted three times and it wasn’t easy coming here at 9am and leaving at 7.30 or 8pm.

“So that’s the reason why we should have the roof here. I’m hoping we’re going to have it very soon,” added the Serb after joining athletes such as golfer Tiger Woods and boxer Lennox Lewis in the $US100 million club.

Djokovic will be back in action on Thursday to contest his 28th successive major quarter-final against Czech seventh seed Tomas Berdych, a 6-3 7-5 6-3 winner over 2013 runner-up David Ferrer.

In contrast, Austrian tyro Dominic Thiem was enjoying his most successful run at a grand slam after beating Spaniard Marcel Granollers 6-2 6-7 (2) 6-1 6-4 to set up a last-eight clash with Belgian David Goffin.
