The former world No. 1 suffered a shock first-round defeat to Benjamin Bonzi in New York—a match that saw him fined $42,500 for unsportsmanlike conduct after berating umpire Greg Allensworth and delaying play for nearly seven minutes.

Soon after, Medvedev announced he was parting ways with longtime coach Gilles Cervara, who had been by his side since 2017, and fitness trainer Eric Hernandez.

“Amazing 8-10 years together,” Medvedev wrote in a social media post, thanking Cervara for their run that included 20 titles, the world No. 1 ranking and his 2021 US Open triumph. “I am grateful to you for guiding me through all these years and let’s see what life brings us in the future.”

Over the weekend, fans got their first glimpse of what’s next. Medvedev’s agent, Olivier van Lindonk, shared a photo of the 29-year-old practicing in Monte Carlo with 2002 Australian Open champion Thomas Johansson, captioned simply “#trainingday”.

Johansson, a former world No. 7, has previously coached Caroline Wozniacki, Maria Sakkari, David Goffin and most recently Kei Nishikori. Joining him on Team Medvedev is Rohan Goetzke, former director of tennis at IMG Academy. The hires were first reported by Sofia Tartakova of Bolshe!, where Medvedev serves as an ambassador.

The shake-up comes after a stagnant stretch, which has seen Medvedev make just one ATP final appearance this year, in Halle, and win only one Grand Slam match in 2025. Ranked No. 5 at the start of the season, he has now slipped to No. 18.

Medvedev is set to return to competition next week at the Hangzhou Open, an ATP 250 event beginning September 17, where he’ll be one of the top seeds alongside Karen Khachanov and Andrey Rublev.
