Alexander Zverev lifts lid on allegations of domestic abuse

He changed that stance at his press conference ahead of the Nitto ATP Finals in London, saying: “Many people have asked me why I kept my mouth shut, why I didn’t say anything.

“While I very much regret that those accusations are made, I have to stick to my initial thing of them being untrue and continue to deny them.

“These accusations are just unfounded and untrue. We had our ups and downs but the way our relationship is described in the public is not how it was. That’s not who I am, that’s not how I was raised by my parents.

“It makes me sad the impact that such false accusations can have: on the sport, on the outside word, on myself as well. I truly apologise that the focus has shifted away from the sport.”

The ATP issued a statement on Friday which read: “The ATP fully condemns any form of violence or abuse. We expect all members of the Tour to do the same, and to refrain from any conduct that is violent, abusive, or puts others at risk.

“In circumstances where allegations of violence or abuse are made against any member of the Tour, legal authorities investigate and due process is applied, we then review the outcome and decide the appropriate course of action. Otherwise, we are unable to comment further on specific allegations.”

Zverev will play his first match at the O2 Arena on Monday against Daniil Medvedev, with play beginning on Sunday behind closed doors.

Close to three million fans have made the trip to Greenwich since the tournament was first held in London in 2009 and it is hugely unfortunate that that tally will not be added to before the ATP’s showpiece event heads to Turin next year.

Nadal, who takes on Andrey Rublev on Sunday evening, said: “The experience to play the ATP Finals at the O2 here in London has been one of the best, without a doubt.

“The atmosphere in this amazing stadium, the organisation has been great, the event has been very popular around the world, so I think the ATP made a great job choosing the O2, choosing London and creating a fantastic event for so many years.

“Of course in an event like this one I think tennis needs to keep moving, but at the same time it’s not fair to finish here in London without crowds. But that’s the thing that is happening today in this world.

“Just congratulate London for this amazing 11, 12 years that we have been playing here and I expect to have another great event in Turin.”

The coronavirus pandemic has meant a very different experience for the players, who usually stay at a central London hotel and travel to the O2 by boat.

This time their hotel is close to the arena and they are not even allowed to walk between the two.

“We are very lucky to keep playing our sport,” said Nadal, who is making another attempt to win the biggest title still missing from his CV.

“That’s the only thing that I can say. I can’t be negative. Of course it will be sad, especially playing with no crowd in this amazing stadium.”

Novak Djokovic, who opens his campaign against debutant Diego Schwartzman, is the top seed having guaranteed he will finish a season ranked world number one for the sixth time.

He is hoping to equal Roger Federer’s record by winning a sixth ATP Finals title, and said: “Coming into the tournament and knowing I clinched the year-end number one, for sure it releases some of the pressure but at the same time it doesn’t change what I hope to achieve in this tournament and why I’m here.

“I really want to win every single match that I get to play and try to get my hands on the trophy. I’m really hoping that I can end the season in the best possible way. The success that I had previously here helps me feel more confident.”

Jamie Murray and Neal Skupski saw their hopes of qualifying for the doubles field end despite reaching the Sofia Open final.

By matching Murray and Skupski on Friday, Austrian Jurgen Melzer and Edouard Roger-Vasselin of France clinched the final spot.
