Mats Wilander spoke highly of Novak Djokovic during Wimbledon. The former Swedish player said: "When he’s at his best, I think he breaks the world record in how good you can play tennis. He does it on every surface, and does it against every match-up.
He doesn’t have a problem with Nadal or a problem with Roger Federer. The other two always had that, and he doesn’t. And he does it against any style of player, doesn’t matter if it’s a big-server, it doesn’t matter if it’s [Roberto] Bautista Agut, doesn’t matter if it’s clay, or grass, or hard court.
He’s basically the only one I think that looks unbeatable for longer periods of time”. Before the final against Roger Federer, Wilander had said: “The problem with Novak for everybody is that we have not seen 50 per cent of his ability so far.
You see 80 per cent at times, and then he cleans them off the court. And then he goes down to 40, because he doesn’t really – I don’t know, he couldn’t be bothered, because he’s too good. It’s like he’s not fully into it because I think he knows he’s so much better than most of them, especially here."
