He is deserving of it. He has worked very hard.Federer, who was 19th in majors, is closing in on Rafael Nadal's record of 20, which he held with Djokovic. Federer had two knee surgeries in 2020 and said that Djokovic has made it clear that he doesn't believe he's still playing. Rafa is the same. I do my own thing. I had my own problems with the knee. This has been my focus.Federer stated that he had made it to the fourth round of a major for the 69th consecutive time in his career. It is a proof to me that I can wake up every morning and that it has been a good thing.I have played a lot tennis. It has been a great experience and I look forward to the next few. It's a great pleasure to play right now. This one is special because I'm almost 40. It was the last round before hitting the big 40. It's all a bonus at this point, and I'll see how far we can go.
