In an interview to EFE the former world No. 1 Mats Wilander said he expects big things from the younger guys in the upcming US Open. Wilander said: "I will be surprised and disappointed a lot if one or two younger players cannot reach and go beyond the semifinals on a hard court.
On grass you need experience, on clay a certain gamestyle, but on a hard court, you literally have no excuse. We need two guys in the semifinals that are not called Roger, Rafa, Stan or Novak. I think Nadal is the only one who can beat Novak Djokovic in a five-set Grand Slam match.
Daniil Medvedev can beat him too, but Nadal is the biggest threat for Novak." On Roger Federer, Wilander said he has doubts: "I think the biggest difficulty is that he will have to play seven matches. It doesn't matter what the gamestyle is, you can have a problem against a big server or a baseline guy."
On Nick Kyrgios, he concluded: "I hope he doesn't behave like he did in Cincinnati. Week after week he is showing more and more interest in wanting to win tennis matches and wanting to improve everything. But not his behaviour.
But I do not care, I think that when he did what he did in Cincinnati, there are kids on the grounds and the language is a bad one. But at least over the last weeks he is showing he cares. Nick wants to win, hates losing, and wants to play well, wants to entertain and he was not just able to deal with it in a professional way.
That's what happened to John McEnroe and Grigor Dimitrov. He can beat all the best players. There are many guys who can make the best players struggle and he is one of them."
