Mark Petchey: Alexander Zverev will become a Grand Slam winner

Alexander Zverev will become a Grand Slam winner, he just needs time according to former tennis player turned commentator Mark Petchey.

Despite huge expectations on his young shoulders, Zverev crashed out of this year’s Australian Open when he lost to Hyeon Chung in the third round.

It meant for the 11th successive time he failed to reach a Grand Slam quarterfinal.

But while fans of the 20-year-old are concerned, Petchey has full confidence in the German – he just needs time.

“I’m not worried at all,” Petchey told Sky Sports.

“He’s still only 20 and he’s had a fantastic start to his career.

“People were writing the same rubbish about [Roger] Federer at one stage, and look at what his career has turned out to be like.

“I have absolutely no doubt that Zverev’s going to be a major winner in a multiple way.

“Once he gets to a certain stage of a Grand Slam it will all fall into place.

“It’s all about time and he’s got absolutely loads of it on his side.

“There will be a lot of youngsters out there right now who would be quite happy if they had his career.

“He wants more and obviously he will be disappointed he couldn’t have more in Australia, but it will come.”
