The goals of tennis pro Alexander Zverev have not changed even after the difficult injury last year.

“I’m still young enough to say they shouldn’t change,” said the 25-year-old from Hamburg at the Munich sand court event. The German is still missing a Grand Slam victory. Becoming number 1 in the world is also a declared goal of the Olympic champion.

Zverev is confident that he will soon be able to show his best tennis again. “It will go back to 100 percent. I think I’m playing better every week and I hope the next one will be even better,” said Zverev.

At the same time, the German admitted: “For me, the impatience is always there. You want to come back and from the first moment, maybe play even better than before”.

The strong performances in the previous week in his adopted home of Monte Carlo make Zverev positive. The bitter round of 16 after missed match points against the Russian Daniil Medvedev is ticked off. “This one or two percent is still missing. Of course I have to win matches like this again to say that I’m 100 percent back”.

Tennis: Alexander Zverev does not have a mental coach

Zverev doesn’t think much of working with mental trainers. “I don’t believe in that,” he said. He has tried in the past to work with a sports psychologist. “But I have the feeling that they cause more problems than they really exist,” said the native of Hamburg.

The two-time winner of the Munich clay court tournament is one of the few top professionals who don’t have a mental coach on their team.

Zverev agreed that tennis is a head sport. “But these are problems in your own head and not in someone else’s head,” said the German, who is aiming for his third title at the Iphitos facility after 2017 and 2018.
