The Swiss champions underwent two surgeries on his right knee last year and has not yet recovered full form.
The former world number 1 failed to make it past the quarter-finals at Wimbledon, where he was neatly defeated by Hubert Hurkacz and even managed a bagel in the third set.
A few days later, the 39-years-old from Basel announced that he would not take part in the Tokyo Olympic Games due to a knee relapse. She did not fare better to Serena, the victim of a slip during her first round match at the Championships.
The American was forced to retire, having to postpone the engagement at Margaret Court for the umpteenth time at 24 Slams. For both of them, 2021 could represent the last season of their wonderful careers, even if you should never take anything for granted when it comes to such legends.
It is not uncommon for athletes from other disciplines to use tennis players as a source of inspiration. This is the case of PV Sindhu, the badminton star, who never hid to admire the class of Roger and Serena.
Federer and Serena have given up on the Olympics
Sindhu said: “Serena Williams still believes she can do it, despite advancing age and the fact that she is a mother.
She has accomplished incredible feats, she is a strong and determined woman. Roger Federer is also an absolute legend. Maintaining that level, at his age and after everything he has won, is not easy at all. They are two extraordinary examples of longevity.”
The Indian badminton player won the silver medal in the women’s singles at the Rio 2016 Olympics. Her race was interrupted by the then world number 1, the Spanish Carolina Marin. In Tokyo, Sindhu easily passed the first round by clearly beating Israeli Ksenia Polikarpova. Both Federer and Serena are expected to be present at the US Open, injuries permitting. We will know more in a few weeks.
