Alexander Zverev has responded to domestic violence claims by his former partner as ‘unfounded’.

In a statement released on Twitter, the world No.7 said he was ‘sad’ to read reports concerning what his ex-girlfriend has said.

“They are simply not true,” he said.

Sharypova claimed Zverev tried to “strangle her’ during an argument at the US Open last year.

Zverev is alleged to have pushed her against the wall before saying “no one cares about her, no matter what he does.”

“There are the unfounded accusations of my ex-girlfriend Olga Sharypova, which I read in the media today,” Zverev said.

They make me very sad.”

“We have known each other since we were children and shared many experiences together. I very much regret that she makes such statements because the accusations are simply not true.

“We had a relationship but it ended a long time ago. Why Olga is making these accusations now, I just don’t know.

“I really hope that the two of us will find a way to deal with each other again in a reasonable and respectful way.”
