Coco Gauff has stunned the tennis community by making a major career move ahead of the 2025 US Open. The American decided to part ways with her coach Matt Daly just days before her campaign at the New York Major.
Gauff joined forces with Daly in September 2024, shortly after announcing her split with Brad Gilbert. Alongside her longtime coach Jean-Christophe Faurel, Daly led the World No. 3 tour-level titles, including her maiden WTA Finals crown and second Grand Slam title at this year’s French Open. However, after less than ideal results at Wimbledon and the WTA 1000 events in Montreal and Cincinnati, Daly confirmed that their partnership had come to an end.
Despite their shocking and unexpected split, Matt Daly made it clear that there was no bad blood between him and Coco Gauff and said that he enjoyed the experience of working with her.
