Dusan Lajovic saves a set point and then manages to hold serve to put a game on the board. It's the least he deserves for his endeavour out on Philippe Chatrier. However, Rafael Nadal will serve for the set.

In the men's draw on Sunday, Roger Federer failed to make the quarter-finals of a Grand Slam for the third time in the last four majors with a five-set defeat to Ernests Gulbis, the 18th seed.

Gulbis will play Tomas Berdych in the last eight after the sixth seed beat big-serving American John Isner. Novak Djokovic cruised into the quarter-finals, beating home favourite Jo-Wilfried Tsonga for the loss of just six games. The Serb plays eighth seed Milos Raonic.

For those of you who had a sleepy Sunday and missed the action, you missed a humdinger of a match between 2012 French Open champion Maria Sharapova (pictured) and 2011 US Open champion Sam Stosur, with the former reeling off nine games in a row to win in three sets. The Russian will play Garbine Muguruza, Serena Williams' conqueror, in the quarter-finals.

Elsewhere, Carla Suarez Navarro beat Ajla Tomljanovic in straight sets to set up a last eight match with 18th seed Eugenie Bouchard, who beat eighth seed Angelique Kerber for the loss of just three games.

You've got to hand it to Dusan Lajovic, the Serb is really going for his shots out there against Rafael Nadal. He works up a lovely point, driving a forehand down the line and following it in before putting away a tidy volley. Unfortunately, he can't do that often enough, Nadal's heavy topspin and brutal hitting simply too much and Lajovic finds himself staring at a first set bagel at 5-0 down.

David Ferrer, last year's French Open finalist, has regained the momentum out on Suzanne Lenglen, the Spaniard breaking Kevin Anderson's serve and consolidating the break to go 3-0 up.

Playing Rafael Nadal for the first time is going to be pretty intimidating so it's no surprise to see Dusan Lajovic displaying a few nerves out on Phillipe Chatrier, a court Nadal has made his home. The Serb hits nine unforced errors in the opening three games, to Nadal's one, and finds himself 3-0 down at the changeover.

"It's verging on the warm for the first time in living memory and Chatrier has already been treated to a nerve-shredder as Petkovic edged past Bertens. A huge result for the German, who missed much of 2012 and 2013 with a succession of injuries, and her coach lived every moment in the stands. He'll need as much rehab as his player after that."

It was all going rather swimmingly for fifth seed David Ferrer over on Court Suzanne Lenglen, the Spaniard cruising through the first two sets 6-3 6-3 in his fourth round encounter against South Africa's Kevin Anderson. However, the 19th seed has hit back in the third, snatching the set 7-5 in the tie-break so we're into a fourth.

Dusan Lajovic, the world number 83, is bidding to become the lowest ranked player to defeat Rafael Nadal since number 135 Steve Darcis at Wimbledon 2013. How do you rate his chances? Can you see past a Nadal-Djokovic final?

And what about in the women's draw? Can the highest remaining seed Simona Halep win her first Grand Slam or is 2012 French Open champion and seventh seed Maria Sharapova the one to beat?
