Serena Williams jokes her daughter is more interested in Play-Doh than her tennis play

SERENA Williams created Grand Slam history but admits her daughter doesn’t understand her mum’s popularity.

In just under an hour the American swatted aside Russian Anastasia Potapova 6-0 6-3 in the first round of the Australian Open in Melbourne.

Williams is the first woman to win 350 major matches in the Open era, increasing her lead over Martina Navratilova (306 wins), Chris Evert (299) and Steffi Graf (278).

Earlier this month, Williams was victorious in the singles event in Auckland, winning her first ATP title since giving birth.

Yet her two-year-old daughter Olympia still doesn’t recognise what her megastar mum does for a living – and in certain motherhood circles her fame is underappreciated.

The 38-year-old, who has banked £71.2m in prize money, said: “It was amazing to win in New Zealand.

“I hadn’t been able to win as a mum before. I had been close. So this was special for me and for her – I hope.

“Sadly, she didn’t know what it meant. She only cares about Play Doh and that’s about it.

“I try to tell her I am somebody. But she doesn’t know.

“I’m known as ‘Olympia’s mum’ to all her friends. And I love that.”

Williams, who once had small blood clots on her lungs, says she was concerned about the air quality in the city, and has been monitoring updates from the authorities on a regular basis.

She said: “I definitely was concerned, and am. It changes every day.

“There are a lot of factors on how it can change. That’s still a concern for pretty much everyone.

“Every day all the players and the tournament make sure that all the players are updated on what the play conditions would be like.”

After winning in Auckland, Williams donated all her £20,000 prize money to the bushfire relief fund following devastating fires across Australia this summer Down Under.

Obviously, for a woman with her size of bank balance she can afford to be charitable.
