A great enthusiast, Wawrinka has no plans to retire just yet: "Just because you're getting older doesn't mean your passion has to disappear".

Somewhat like Andy Murray, Stan Wawrinka displays impressive strength of character. Despite a steadily declining level of tennis and some very disappointing results, the 39-year-old Swiss doesn't seem intent on putting away his rackets.

A true enthusiast, the man now ranked 89th in the world explains: "I think it's important as an athlete to set goals. I also know that the goals I had ten years ago are not the same today. I think it's also a good example for young people, you want to show them that just because you're getting older doesn't mean your passion has to disappear.

You have to remember that when I started playing tennis, it was about the game, playing with my friends, being passionate and enjoying it, and that's still the case. I think it's for young people who want to dream of that to understand that whatever you achieve, whatever your age, wherever you are, you have to do what's right for you."
