The 20-time Grand Slam champion needed an extra operation on his right knee and plans to be back in 2021, when he will turn 40. Prior to that, he lost to Novak Djokovic in the semifinals of the Australian Open in January. The Olympics, where Federer was planning to play and was seeking that elusive gold medal in singles, was pushed to 2021. Now everyone who follows tennis, including Federer, is curious how long this “Golden Age” can last.
