Roger Federer crushes Grigor Dimitrov's backhand lob with an overhead slam in their 2019 US Open Quarter-Final match. The Swiss player said: "Look, Serena and me, she started even earlier than I did on the tour. She's also had many more injuries than me and more time off away from the game than I did.
We went about it different ways, totally different backgrounds and all that. Still I guess you need to be successful, you need to love what you're doing, find a way to really keep yourself entertained because you go through moments where maybe being away from your home city, village, country, house, whatever it may be, friends, it's not that fulfilling. You sometimes got to look for ways to keep going."
