Serbia's Novak Djokovic came from two sets down to win his fourth round tie against Italian teenager Lorenzo Musetti at the French Open at Roland-Garros in Paris.

The world number one looked to have an easier route to the final after Swiss tennis legend Roger Federer, his potential opponent in the last eight, pulled out due to injury concerns yesterday.

This gave Italian ninth seed Matteo Berrettini a bye to the quarter-finals.

However, he first had to defeat unseeded Italian teenager Musetti, but went down two sets to the youngster in tiebreakers.

Djokovic expectedly fired up with the pressure on - replyed by winning the third set 6-1 and then the fourth set 6-0.

In the fourth set, the Serbian dropped just four points.

Musetti seemed to be struggling physically and eventually retired hurt in the fifth set with the score at 4-0 to Djokovic in the decider, and Musetti's movement appearing to be severely hampered.

It finished 6-7 (7-9), 6-7 (2-7), 6-1, 6-0, 4-0.

Following on court was the King of Clay, Spain's Rafael Nadal, who has won the French Open a record 13 times.

Nadal faced young Italian upstart Jannik Sinner in his match and despite the 18th seed keeping the Spaniard honest in the first two sets, Nadal triumphed in straight sets 7-5, 6-3, 6-0.

Argentinian 10th seed Diego Schwartzman won in straight sets in a tight encounter with Germany's Jan-Lennard Struff, prevailing 7-6 (11-9), 6-4, 7-5.

In the women's draw, defending champion Iga Świątek remains the only top ten seed in the draw, after overcoming Ukrainian teenager Marta Kostyuk 6-3, 6-4 in the night session match at Court Philippe-Chatrier.

American teenager and 24th seed Coco Gauff defeated Tunisian 25th seed Ons Jabeur 6-3, 6-1, while Czech Republic's Barbora Krejčíková is also through to the quarter-finals following a 6-2, 6-0 thrashing of the United States' Sloane Stephens.

Greek 17th seed Maria Sakkari pulled off the upset of the day in the women's singles, soundly defeating American fourth seed and last year's runner-up Sofia Kenin 6-1, 6-3 in just over an hour.

In the men's doubles quarter-finals, Spain's Pedro Martínez and Pablo Andújar defeated India's Rohan Bopanna and Croatia's Franko Škugor 7-5, 6-3, while Kazakhstan's Andrey Golubev and Alexander Bublik are through after a 6-4, 6-4 win over Monaco's Hugo Nys and Tim Pütz of Germany.

Krejčíková was unable to win her second match of the day with partner Filip Polášek of Slovakia, as the top seeds were knocked out in the mixed doubles quarter-finals.

Giuliana Olmos of Mexico and Juan Sebastian Cabal of Colombia defeated the top seeds 6-2, 5-7, 12-10.

Finally, Russians Ruslan Karatsev and Elena Vesnina upset American second seeds Rajeev Ram and Nicole Melichar in the other mixed doubles quarter-final, coming from a set down to win 6-7 (3-7), 6-2, 10-8.
