Serena Williams’ husband has hit out at Madrid Open tournament director Ion Tiriac after he said the tennis star should consider retirement.

Alexis Ohanian wrote on Twitter: “Safe to say no one gives a damn what Ion Țiriac thinks.”

It comes after Tiriac criticised the 23-time grand slam champions’ age and weight, before adding that if she had a ‘little decency,' she should call time on her stellar career.

Tiriac said on Romanian television: "At this age and the weight she is now, she does not move as easily as he did 15 years ago.

“Serena was a sensational player. If she had a little decency, she would retire. From all points of view.”

It is not the first time Tiriac has hit out at the 39 year-old after he questioned her physical condition in 2018.

He said then: “With all due respect, Serena Williams is 36 and 90 pounds I would like to see something else, I would like to see a player like Steffi Graf.”

To which Williams replied: "Clearly there’s more to women’s tennis than me. There’s a lot more, but I’ll have words with him, believe me, I’ll have words with him.

“It’s an ignorant comment, and it’s a sexist comment, and maybe he’s an ignorant man.”
