Fissette says Swiatek was not happy from the start.
According to Fissette, his time with Swiatek never really clicked. He shared that she wasn’t comfortable with the way they were working together, especially compared to her experience under Tomasz Wiktorowski.
He also made it clear that these issues weren’t a big secret inside the team. They had talked about them openly from early on.
Following her early exit at the Miami Open, she is preparing for her next tournament appearance at the Charleston Open on April 5th against Magdalena Frech.
This event could be an opportunity for Swiatek to bounce back after recent struggles and settle into her new coaching setup. Francisco Roig will be by her side as she looks to regain some momentum after parting ways with Fissette.
Wim Fissette speaks about his time with Iga Swiatek

In an interview with The Athletic, Fissette took responsibility for Swiatek’s recent struggles on the court, acknowledging that the results hadn’t been good enough.
“There are some teams that can stay really calm under, let’s say, difficult conditions,” he said. “Others feel like something needs to change. As in every sport, it’s always first the coach that has to go.”
“At the highest level in sports, this is part of the job. You have to accept that. They were almost unbeatable for a few years. The expectations are going to be super high. Every loss will hurt extra.”
Fissette pointed out some of the obstacles he faced during his tenure with Swiatek, including a language barrier and fitting into a team structure that already included psychologist Daria Abramowicz.
“I was aware of the difficulties in this project,” said Fissette. “It was impossible to do better. But I was still really happy that I took the challenge, and happy with what we achieved.”
“Iga is such an extraordinary player and athlete,” he added. “Every word I say is new to her. Out of respect for Iga, I don’t want to go deep into that.”
Fissette won’t be out of work for long, though – he’ll soon return to action as Belgium’s coach when they take on the United States later this month in their Billie Jean King Cup tie.
Looking back at Iga Swiatek’s record with Wim Fissette
Fissette spent just over a year working with Swiatek, but her results in that time were still strong.
She might not have dominated quite as much as in previous years, but she still finished the 2025 season with a 64-17 record.
That’s good for a 79% win rate, something most players on tour would be more than happy with.
But despite all those wins, she managed only three titles – and all of them came within two months late in the summer.
Swiatek won Wimbledon, the Cincinnati Open, and the Korea Open between July and September, but didn’t reach another final under Fissette after that run.
