SERENA Williams is already planning her return to tennis and her coach has revealed it is sooner than many think.

Williams announced in April that she was pregnant with her first child with fiance Alexis Ohanian only months after she won her 23rd grand slam title at the Australian Open.

She is determined to return and is adamant her career isn’t over, with coach Patrick Mouratoglou revealing she is planning a remarkable return at next year’s Australian Open in January.

“For anyone, it sounds impossible, because it’s too short a time after you give birth,” he said.

“But Serena is Serena. There is no rule that you can apply to Serena. She has a body that is not anybody’s body. She has a will that is also completely unusual. She is one of a kind.”

As if to emphasise that, Mouratoglou also revealed Serena recently sent him a text message making her intentions clear.

The message read: “’It’s going to sound weird, but I’m going on the court. I don’t want to lose my touch’.”

The Frenchman has been working with Williams since 2012 and their partnership will continue when she returns to the sport.

Williams won her 23rd title at this year’s Open while pregnant, defeating sister Venus in straight sets.

If she plays at next year’s tournament it would be only months after giving birth.

She made a surprise appearance at the French Open to watch Venus storm into the third round with a straight sets win over Japan’s Kurumi Nara.

After the match her sister accidentally revealed her sister is expecting a baby girl when asked what she hoped the baby would call her.

“She’s going to call me ‘favourite aunt’,” she said.

Former world No. 1 Victoria Azarenka will return to tennis in about a fortnight when she plays at the Mallorca Open in Spain after giving birth to her first child, Leo, in December.

Azarenka will then play at Wimbledon.
