The tennis world witnessed another coaching change as Patrick Mouratoglou and Naomi Osaka officially ended their 10-month partnership. What started with promise in Beijing has concluded with mutual respect, leaving fans wondering what’s next for the four-time Grand Slam champion still searching for her path back to tennis’s summit.
How Did Patrick Mouratoglou and Naomi Osaka Handle Their Professional Split?
The surprise announcement of their split came just days after Osaka was knocked out of the Mubadala Citi DC Open in Washington, losing in straight sets to former US Open champion Emma Raducanu. The early exit marked another setback in the Japanese star’s inconsistent return to the tour.
In his farewell message, Mouratoglou shared a thoughtful series of images chronicling their months together on tour, writing in the caption:
“Nothing lasts forever. What counts is what a collaboration has brought to each other and what lasts after. After 10 months of collaboration, we have decided to part ways professionally. I am grateful for the trust, the journey and what we have built together. I will always root for you and wish you nothing but the best.”

The post was Mouratoglou’s first and only public acknowledgment of their professional split. The gracious sentiment echoed the message Osaka shared earlier that same day via her own Instagram story, in which she thanked Mouratoglou and called him “one of the coolest people I’ve ever met.”
“Merci Patrick ❤️ it was such a great experience learning from you. Wishing you nothing but the best. You are one of the coolest people I’ve ever met and I’m sure I’ll see you around 🙏🏽”

Osaka and Mouratoglou officially teamed up in September 2024, shortly after her separation from longtime coach Wim Fissette following the US Open. Their partnership kicked off at the China Open in Beijing, where Osaka made an encouraging run to the fourth round.
Under Mouratoglou’s guidance, she showed flashes of her top form, most notably reaching the final at the ASB Classic in Auckland and capturing her first-ever clay-court title at the WTA 125 event in Saint-Malo.
She also reached the fourth round at the Miami Open and Italian Open and had third-round finishes at both the 2025 Australian Open and Wimbledon. However, despite these promising signs of resurgence, a major title remained frustratingly elusive.
Osaka, currently in Montreal ahead of the Canadian Open, will face Canadian qualifier Ariana Arseneault in the opening round of the WTA 1000 event. If she advances, she’ll meet 13th seed Liudmila Samsonova in the second round.
The tournament represents another opportunity for Osaka to find her rhythm without the guidance of Mouratoglou, who had been working to help her recapture the form that once made her the world’s top-ranked player.
