2020 US Open champion Dominic Thiem insists that Alexander Zverev is "the most dangerous opponent" for Novak Djokovic as the Austrian thinks the German knows how to beat the Serb. Zverev, ranked at No. 4 in the world, recovered from a set and a break down to beat Djokovic in the Tokyo Olympics semifinal.
Now, Djokovic and Zverev are set to meet in the US Open semifinal. No. 1 seed Djokovic is the favorite but Zverev has proved that he is more than capable of beating the Serb on the biggest stage. "Sascha (Zverev) is the most dangerous for Novak (Djokovic), because of his serve, because of his game.
He knows how to beat him - he did it recently at the Olympics - and he believes in himself to do it again. Popcorn match," Thiem told Eurosport, as revealed on Tennis Majors.
Djokovic wary of the Alexander Zverev threat
"He's in a fantastic form," Djokovic said of Zverev.
"Next to Medvedev, best form. But it's best-of-five. It's Grand Slam. Of course looking at his results in past few years, he's played very well here on this court. He was a couple points away from his first slam last year against Dominic.
"I know it's going to be battle, even harder than it was today. But I'm ready for it. Look, these are the hurdles that I need to overcome in order to get to the desired destination. Result is something that I can't predict, but I can definitely put myself in the best possible state of mind and body to perform as well as I can.
"I know his game. As I said, I know his game very well. I've seen him play. He's been playing very, very well. Again, semis. When we face each other, there's nerves, a lot of things on the line. It could go both ways. I think very few points will really determine the winner there. Let's see what happens."
