Wawrinka has set himself high standards and at the age of 38, believes he can still beat the world’s best players. Speaking at the US Open last month, he said: “Physically I think I’m okay. I’m old, of course, but I feel good. I was feeling good on the court against younger players.
“I also know the day I stop I will never find those emotions anywhere. I’m enjoying what I’m doing. I think it’s an amazing life, and we are lucky to be tennis players and to travel the world, to play in the biggest tournaments. If you [are] still passionate about something, you shouldn’t stop or change.
“I never forgot why I started playing tennis and what I was dreaming of when I was young was to play the US Open, to play those Grand Slams, big tournaments, ATP tournaments, to be there. I’m happy I can still play at that level.”
