Tennis coach Rick Macci has highlighted what Naomi Osaka needs to do to return to her very best. Former world number one Osaka has had a tough time ever since returning to court after taking a long break to deal with pregnancy.

Osaka, a four-time Grand Slam champion, has been in a career rut for years. Mouratoglou joined her staff in September of 2024 and there hasn't been much improvement. Osaka has not made it past the third round of a Grand Slam tournament since 2021 when she won the Australian Open. Now she will look for a new coach to help bring her back to form.
