The world number three confirmed the decision in a statement on Instagram, conceding that recent results, most notably in Miami, had forced a period of reflection.
“Sometimes life and sport bring moments like this,” she wrote. “Miami was especially difficult for me. I feel disappointed and frustrated, and I take responsibility for what happened on the court.
“At the same time, I have drawn several important conclusions, which I will carry forward. After many months of working together with Wim Fissette, I have decided to go my own way.”
Swiatek was at pains to emphasise that the rest of her team will remain unchanged, while also thanking Fissette for his role in reshaping elements of her game -- work that ultimately culminated in her long-sought Wimbledon triumph.
“I know there are many questions,” she continued. “But I will share more about what comes next at the right time. For now, I need a moment to look after myself, process this experience and prepare for a new chapter -- step by step. As I often say, it’s a marathon, not a sprint.”
The partnership, formally announced on 17 October 2024, began during a turbulent spell in Swiatek’s career, shortly after a suspension following the detection of a banned substance. Under Fissette’s guidance, she introduced technical adjustments that produced mixed returns.
While her dominance on clay waned, she made significant strides on grass, reaching a first final in Bad Homburg before going on to secure her maiden Wimbledon title. Yet the broader 2025 campaign proved underwhelming by her own high standards. Aside from her success at the All England Club, she claimed just one WTA 1000 title in Cincinnati and struggled against top-ranked opponents.
Fissette, for his part, reflected warmly on their collaboration.
“In 2018, I met Iga at the Wimbledon Champions’ Dinner after her junior title,” he said. “Seven years later, we won it together -- a beautiful story.
“We both aimed for more and worked tirelessly towards it. Along the way, we shared special moments and learned valuable lessons. Iga, I wish you every success in what comes next. I have no doubt you will achieve it.”
