"I think mentally he's the best player to ever play the game" - Zverev sends Djokovic high praise after US Open defeat

Alexander Zverev couldn't complete an Olympic sized feat at Flushing Meadows as he lost out to Novak Djokovic in the semi-finals of the US Open.

Djokovic is on the verge of making history by claiming the calendar Grand Slam and post match the German was full of praise for his winning opponent.

“It was a great battle. Kind of a little bit disappointed with the start of the fifth set. To be honest, apart from that, it was a good match. I think we both left it all out there,” Zverev said.

“The second break in the fifth set was so ridiculously unlucky that it sometimes happen. But he's No. 1 in the world for a reason and he showed that tonight.”

“There is a reason why he's won 20 Grand Slams. There's a reason why he's spent the most weeks at World No. 1. There's a lot of reasons for that.

“I think mentally he's the best player to ever play the game. Mentally in the most important moments I would rather play against anybody else but him.”
