This is mainly due to the fact he has yet to advance beyond the quarterfinal stage at a major, and after losing to Alex De Minaur, Stefanos Tsitsipas and Denis Shapovalov all in straight sets at teh ATP Cup he has been practising day and night to correct his game ahead of the tournament.
“I have been practising five to six hours, seven hours sometimes a day, which nobody really does a week before a Grand Slam,” Zverev revealed in a press conference on Friday.
“I need to get my tennis back, because how I was playing at the ATP Cup was just not good enough to do well in a Grand Slam. I know that, my team knows that. All I’ve been thinking about is basically how to practice, how to prepare myself. There’s nothing else really that matters right now.”
“I’ll probably have more confidence than at the ATP Cup, that’s for sure,” he added.
“Look, I know I’m probably not the favourite to win this title. Other players are playing better than me, so this is also a process, but I’m happy just knowing that I can go out there and feel comfortable.”
“Normally what happens with me is that the further I go in the tournament, the better I start playing and I’m hoping this will be the case. We’ll see how it goes.”
Zverev also gave his thoughts on Nick Kyrgios and said that he believes he doesn't have the game in the Grand Slams to win them and that Stefanos Tsitsipas is a better player in his eyes.
“I think there’s a lot of young guys that are right now, no offence, just better than him,” added Zverev on Kyrgios.
“I think Tsitsipas is better than him, just simply because he’s more consistent over five sets. To beat the best, you have to play at your best for a longer period of time. But I think a lot of young guys have a chance this year, maybe more than the last few years, so it’s going to be interesting to see if there will be some upsets.”
