Naomi Osaka, former world number one and four-time Grand Slam champion, has once again parted ways with her long-time coach, Wim Fissette. The announcement comes after a frustrating stretch of performances, culminating in an early exit from the US Open, which Osaka herself admitted left her feeling disheartened.
The Belgian coach, who began working with Osaka in 2019, played a pivotal role in two of her major career milestones. With Fissette by her side, Osaka claimed both the 2020 US Open and the 2021 Australian Open titles, adding to her impressive Grand Slam tally.
