In an interview to Metro, the 1998 US Open and 2003 Wimbledon finalist Mark Philippoussis explained on what aspect Alexander Zverev needs to improve in order to beat Novak Djokovic, Rafael Nadal and Roger Federer on a consistent basis and in Grand Slams, which are the tournaments where the German has been struggling the most having reached just one quarter-final, at this year's French Open.
Speaking about the Big3 dominance and then Zverev, in London Philippoussis said: 'The crazy thing is that they’re still the guys to beat. It’s incredible when you think about it. The only guy who has stepped up is Zverev.
But he hasn’t done it in Grand Slams yet. He’s far from done it at Grand Slams. He needs to step it up, starting at the Australian Open. His game is staying back on the baseline and that’s no problem but when you’ve got seven best-of-five-set matches to win you need to, you know, kind of get through that first week without working as hard.
In my opinion, he just stays three or four feet too far back behind that baseline and he’s just doing a lot of work. That’s fine in the best-of-three sets, the tournaments that he’s winning three or four of this year but in Grand Slams it’s just a different story.
He’s working way too hard and he’s getting hurt by guys he just shouldn’t be getting hurt by. He’s just way too far back.’ ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
