Naomi Osaka has yet to speak publicly after it was announced she has split from her long-term coach.
Veteran tennis mentor Wim Fissette confirmed their break-up in an Instagram post on Thursday morning, bringing an end to their successful relationship.
Their two-year partnership was the most successful period of Osaka’s career with wins at the 2021 Australian Open and 2020 US Open, taking her grand slam tally to four.

Fissette posted images of his time with Osaka with photos showing them on and off the court together as part of his announcement.
“It has been a privilege to coach Naomi since 2019 and see her grow into the Champion she has become,” he wrote.
“She has inspired a whole new generation to fall in love with the game & to speak up for what they believe in and it’s been incredible to play a part in that journey. Thank you @naomiosaka. I wish you all the best and looking forward to my next chapter.”
It is another big hurdle for Osaka to confront in the bumpy road she has been on recently.
Osaka pulled out from competing at Wimbledon recently when the world’s most prestigious tennis tournament was reduced to an exhibition event as a result of the WTA Tour’s decision to remove all ranking points from the event.
The 24-year-old is still recovering from a turbulent 2021 season where she skipped Wimbledon and quit in the middle of the French Open, citing mental health grounds.
Fissette now joins a long line of coaches to have parted ways with the Japanese superstar.
When he took over as her coach in 2020, he was at the time Osaka’s fourth coach in the space 12 months.
The tennis world is now waiting to hear who the Belgian tennis coach will work with next.
The highly regarded mentor also helped Kim Clijsters and Angela Kerber win grand slams. He also enjoyed success in his work with Simona Halep, Johanna Konta, Sabine Lisicki and Victoria Azarenka.
Osaka, meanwhile, is preparing to make her tennis comeback at the Silicon Valley Classic in California, beginning August 1.
Osaka has been sidelined due to an Achilles injury since her opening round loss at the French Open in May.
She returns to the WTA Tour after a rankings collapse which sees her ranked the No. 38 player in the world.
