Boris Becker believes that Alexander Zverev needs to deliver soon otherwise he'll be overtaken by the new generation of players that is rising recently.
Alexander Zverev was once considered a very bright talent in tennis, particularly because he played so well and won big events at a young age. Many thought he would be a serious rival to the big three in the coming years and a major winner. None of that happened yet and according to Becker time is running out.
Zverev was playing fantastic tennis when he got injured last year. He was at a level that was major winning but the injury will make it a long time before he makes it back there:
"Sascha [Alexander Zverev] has been injured for seven months now, so it will take another seven before he's where he was 14 months ago. That's an eternity in sport and the locker room doesn't sleep. Carlos Alcaraz hardly had a match until 14 months ago won, then he became number one in the world."
Time catching up with players has happened before as you get overtaken by youngsters. That is the fear Becker has for Zverev and he wants to see him deliver in the next few years:
"Youngsters are coming and a 25 or 26-year-old now has to deliver because all too often you don't get the chance anymore. It's going to be a long way back. I think it's possible because he has the right attitude. However, it will be more difficult than two or three years ago. Sascha needs patience, has to play tournaments."
