Alexander Zverev can well imagine Boris Becker returning to German tennis.

"You can always use Boris' help in tennis, whether as a player, coach, DTB or whatever. He knows how to do it," said the Olympic champion of "Bild". Becker is certainly very important for German tennis and "we will always accept the help. He will be welcomed here with open arms".

Becker as a guest at the Davis Cup

Zverev had no contact with Becker after his release from prison, except in a TV slot. "We've both been on the road a lot in the last few weeks, but we'll sit down in Trier. We're very close and I'm happy that he's coming," said the 25-year-old, who is with the German Davis Cup team will play the qualifying match against Switzerland in Trier on Friday and Saturday. It's nice for the whole team that Becker (55) is there.

Meanwhile, Zverev criticized the mode of the Davis Cup and wanted changes. From his point of view, it should either go completely back to the old mode with a duel at the weekend or a big event should take place every two years. "In any case, a team must have home rights. A tournament in two weeks at a neutral location, where two top nations play against each other in front of 400 people, is nonsense and not a Davis Cup," said Zverev. The biggest problem will be that the ATP men's tour and the ITF world association will sit down at a table.

The German number one is optimistic against Switzerland: "I'm sure we'll get the three wins." He himself is fit again after the thigh problems that plagued him at the Australian Open. "Otherwise I wouldn't be here," said Zverev, who had to sit out a long time after a foot operation last year.
