In an interview, the former world No. 1 Mats Wilander commented on the secrets behind Roger Federer, Rafael Nadal and Novak Djokovic longevity. The Swede said: "When you become a superstar the way they are, winning and evolving becomes something you just want to do.
Being the best in the world is not to be the best in the world. It means to be the best for yourself. You have to play at a certain level, having a certain success. Look at Federer. He is not the best anymore, he does not win, but he is still there.
He knows he is 38 years old, he has four children, a lot of people around. What he wants more now is to be as good as he can be at his age. It's the same thing with Cristiano Ronaldo, Tiger Woods, Messi, Mohammad Ali, LeBron James.
Mohammad Ali has been in boxing for a long time, there is something that drives those people, something we cannot see." Wilander also praised the Romanian Bianca Andreescu's potential: "I saw her playing well in the last year's French Open.
I followed her, she has something special to me. She is dangerous, of course, she knows tennis, she has an amazing technique. You can mentally perceive how her game works. She is very easy to look at, look at all the journey she went through."
Wilander commented on the Nadal's legacy in tennis: "Rafa makes people wanting to play tennis but the dangerous thing is that they just want to play tennis, while as a kid you have to play other sports. Rafa's passion comes from football and his movement as well and his understanding of sports in general."
