Roger Federer will play his first clay court match in two years next month.

The twenty-time Grand Slam winner is on the list of participants of the Masters tournament in Madrid published on Tuesday.

Federer has been struggling with a knee injury in recent years.

He made his return to the hard court in Doha at the beginning of March and was to play in Dubai afterwards, but he chose to train.

The Swiss did not feel one hundred percent fit yet.

39-year-old Federer had surgery on his knee in February last year.

After a setback, he had to go under the knife again last summer.

He therefore put an end to his season.

At the beginning of this year, the Australian Open came too early for him.

Despite his long absence, Federer is still in seventh place in the world rankings.

Due to the corona pandemic, fewer tournaments were played and, moreover, a different calculation is temporarily used when determining the ranking.

In addition to Federer, who was the best in Madrid in 2009 and 2012 and reached the quarter-finals with his last participation in 2019, almost the entire world top is on the list of participants in Madrid.

This is also the case with the women, where Kiki Bertens, among others, was presented as a participant, even though she is currently recovering from an Achilles tendon injury.

However, players can still cancel.
