In a recent interview, Serena Williams' coach Patrick Mouratoglou revealed that the decorated tennis player "re-created her body to fight again" post her daughter's birth.

The legendary American star won the Australian Open 2017 when she was eight weeks pregnant. She gave birth to Olympia the following September. The French man revealed that the 23-time Grand Slam winner had every possible trophy on her CV but she decided to continue competing in the sport because she loves the game and believes she can win more major titles.

"At 36, it's even tougher, a woman's body becomes a mother's body when she gives birth. The mother's body is different than the best athlete's body. She re-created her body to fight again. For this reason, she made unbelievable physical efforts. I think she is still far away from her best level but she still is more ready as the time goes on," Mouratoglou told in an interview in Japan.

She now aims to break the all-time record of 24 Grand Slam singles title, which currently belongs to Australian great Margaret Court. Serena is second on the list ahead of Roger Federer, who has 20.

After becoming a mother, Serena has lost four Grand Slam finals - Wimbledon (2018 and 2019) and US Open (2018 and 2019). Serena's coach believes that the pressure of creating history is holding her back.

"If you reach the final, you will have another match left to make history, which is the highest pressure you can experience in sports and probably in life. So there was pressure but everyone expects her to win all the time, so we need to overcome this pressure," Mouratoglou said earlier in an interview.

Ever since Olympia was born, the former World No. 1 has begun to skip several tournaments, something she had not done in the past. With the final Grand Slam done and dusted in 2019, Serena has once again opted to not play in the WTA finals and she'll be back in action only next year in January at the ASB Classic in Auckland.
