Speaking to Adam Scott for Uniqlo, Roger Federer shared what his biggest challenges are in tennis and life at 38 years of age. The Swiss said: "My challenge is a bit time management, my body, making sure I can still stay on the tour, run around, chase those balls, still be successful because no success, you ask yourself the question, What's the point, you have no success after all the success I have had.
You need it to survive on the tour. Just how can I still keep improving, that's so stuble at one point, it's crazy to think that way but when you are growing up, your forehand gets stronger, you are serving bigger, you are doing all these things and you are taking major strides and all of a sudden I should get older.
I don't say you get worse but it's so hard to maintain it, just maintaining means success and that's the challenge and that's a part of the game in the head like in the racket that I am constantly seeking how can I stay as good or how can I just become a little bit better because I honestly feel a much better player than 10-15 years ago even though I had more success back then and that's got to be the challenge, to constantly keep on improving." Federer is eager to seek his 21st Grand Slam title in the US Open. He last triumphed there in 2008, 11 years ago.
