Patrick Mouratoglou has officially joined Stefanos Tsitsipas’ coaching team.
Mouratoglou, who guided Serena Williams to 10 of her 23 Grand Slam titles, will work alongside Thomas Perrin to help the Greek star get his career back on track.
Tsitsipas recently ended the player-coach relationship with his father, Apostolos, for the second time, having parted ways initially in August 2024 before reconnecting in July last season.
What was the biggest shock from the first round of Wimbledon this year?
Plenty to choose from…
The former world number three has seen his ranking plummet over the past year amid injury struggles, and is now 87th in the world.
Following Tsitsipas’ second-round loss at Wimbledon to Novak Djokovic, Mouratoglou issued a statement outlining what his new role will be in the 27-year-old’s team.
Patrick Mouratoglou confirms new role in Stefanos Tsitsipas’ team
In a post on his Instagram account, Mouratoglou said: “I can confirm what Stefanos has said in an interview that I’ll be part of the team.
“I will supervise the practice, the matches and work alongside Thomas Perrin, who’s been the coach of the [Mouratoglou] academy for many years.
“I actually took the decision not to go on tour for a little while for a lot of reasons, professional, personal.
“The relationship I have with Stef for so many years is really strong. He’s someone that is very important to me and I think he’s not where he belongs at the moment in terms of ranking and results.
“The only thing I can do is, you know, we have one week here at the academy. Let’s work together for at least a few days and then we can think of a solution.

“Whenever he’s on tour, I will collaborate with Thomas on a daily basis for all the programmes for practice, to do all the debriefing before matches, also the debriefing after the matches, and prepare the matches.
“I think it’s a good solution. There are a lot of things I cannot see because I’m not here to see them. So I trust Thomas’ eyes and his feedback to get the information that I don’t get directly.
“We try to really collaborate as closely as possible.
“You know, the last two years were really difficult for him. He got an injury. We’re rebuilding around Stef’s strengths.”
Patrick Mouratoglou’s coaching history in professional tennis
Mouratoglou spent the bulk of his coaching career with Williams, but he has had several stints with different players across both the ATP and WTA tours, the first of whom was Marcos Baghdatis.
Under the Frenchman’s wing, Baghdatis became the junior world number one, won the 2003 Australian Open boys’ title and reached his first and only Grand Slam final at the 2006 Australian Open, where he ultimately fell to Roger Federer.
Prior to his tenure with Williams, Mouratoglou helped Anastasia Pavlyuchenkova crack the WTA top 30, guided Aravane Rezai to the 2010 Madrid Open title and assisted Yanina Wickmayer in reaching a career-high ranking of 12th in the world.
As well as the 10 major crowns Williams clinched with Mouratoglou, the American legend also secured three WTA Finals titles and an Olympic gold medal at the London Games in 2012.
Since parting company with Williams in 2022, Mouratoglou has had spells with, Simona Halep, Holger Rune and Naomi Osaka.
He was in Rune’s corner when the Dane clinched his first ATP Masters title at the Paris Masters in 2022, beating Djokovic in the final.
What Patrick Mouratoglou once said about Stefanos Tsitsipas’ major chances
Tsitsipas has come close to winning a Grand Slam in his career, having made two major finals: The 2021 French Open and the 2023 Australian Open.
But the emergence of Carlos Alcaraz and Jannik Sinner, as well as his own struggles, has made it much more difficult for Tsitsipas to claim a maiden Grand Slam crown, which Mouratoglou touched on last year.
In a UTS talk show in 2025, Mouratoglou was asked if he thinks Tsitsipas can ever win a major.
He replied: “Today, it is difficult to believe because the two other guys [Sinner and Alcaraz] are so much better than anyone, and he is not at his level himself, so it is difficult to imagine.
“I think in today’s game, if you want to win a Grand Slam, you cannot have a weakness. It is impossible.
“The guys will kill you on your weakness, so he has to really strengthen his game if he wants to have a chance. Maybe on clay.”
Since reaching the quarterfinals of Roland Garros in 2024, Tsitsipas has failed to make it past the second round at a Grand Slam.
