"I don't know if I'm going to play," said the 39-year-old after he only scored 7: 6 (5), 6: 7 (3), 7: 6 (4), 7: 5 success against the German number three had made perfect. And that in front of empty stands on the Philippe-Chatrier Court.

"Now I have to decide whether to continue playing or not," said the 39-year-old Federer with a view to the round of 16 against Italian Matteo Berrettini on Monday: "Is it too risky to put too much strain on the knee? Is it a good time to take a break? " The form-strong Berrettini was last in the final in Madrid, where he lost in three sets to Alexander Zverev. World number one Novak Djokovic would probably wait in the quarter-finals.

The 20-time Grand Slam winner Federer is playing his first major tournament since the Australian Open 2020 in Paris. As a result, he had two knee operations and had to cope with a laborious rebuilding. Federer had indicated that the clay court season was more of a preparation for Wimbledon. During the entire season, Federer has now played six matches: In Doha against Daniel Evans and Nikoloz Basilashvili, in Geneva against Pablo Andujar and in Roland Garros against Denis Istomin, Marin Cilic and Dominik Koepfer.
