Iga Swiatek and Wim Fissette’s year-and-a-half-long coaching relationship ended this week.
With the Belgian in her corner, Swiatek won Wimbledon, the Cincinnati Open, and the Korea Open last year.
Despite all that success, some have suggested their partnership was a failure.
Does Iga Swiatek now win the French Open after changing coaches? 🤔
Let us know your reasoning in the comments ⬇️
Swiatek’s fellow Pole, and former ATP pro, Dawid Olejniczak, certainly thinks so.
Dawid Olejniczak believes Iga Swiatek ‘lost’ a year and a half of her career with Wim Fissette
Speaking to Interia Sport, Olejniczak shared his damning verdict of Fissette.
“[Wim] Fissette isn’t a coach who builds things up,” he said.
“I’d compare him to coaches in football who take on Real Madrid, Barcelona, or Bayern Munich and get results because they exploit the potential inherent in those teams.

“That’s why I’m not a fan of Fissette.
“I respect him, but it was clear to me from the start that he wouldn’t change Iga Swiatek’s game.
“I didn’t see Fissette’s stamp on Swiatek’s game.
“Iga still plays the same tennis she did before he arrived. Sure, Iga showed some behavior at Wimbledon that hadn’t been there before, but the question is how much of that was Fissette’s doing and how much was Iga’s own doing.
“When Swiatek worked with [Tomasz] Wiktorowski, it was clear he taught her something… We’ve lost a year and a half here.”

Olejniczak, who appeared at Wimbledon in 2008, wasn’t impressed with the advice Fissette gave Swiatek.
“I heard Fissette, and what he said was just gibberish, like ‘let’s keep playing.’ You and I could say that!” he said.
“I’d use the example of [Carlos] Alcaraz’s coach, where the messages sent to the players are short and detailed. Fissette lacked that.
“And if they say Swiatek doesn’t like it, what did Fissette do for those eighteen months?
“Couldn’t he convince her?”
Finally, Olejniczak was asked if he thinks Swiatek should re-unite with her former coach, Tomasz Wiktorowski, with whom she won four Grand Slam titles.
Grand Slam titles won by Iga Swiatek
| Grand Slam | Surface | Coach |
| 2020 French Open | Clay | Piotr Sierzputowski |
| 2022 French Open | Clay | Tomasz Wiktorowski |
| 2022 US Open | Hard | Tomasz Wiktorowski (2) |
| 2023 French Open | Clay | Tomasz Wiktorowski (3) |
| 2024 French Open | Clay | Tomasz Wiktorowski (4) |
| 2025 Wimbledon | Grass | Wim Fissette |
“For now, he’s with [Naomi] Osaka, but I’d be all for it,” said Olejniczak.
“They say you can’t step into the same river twice, but if it were possible, I’d probably sign up for the idea.”
Wiktorowski joined Naomi Osaka’s team in 2025 and immediately found success with the four-time Grand Slam champion, guiding her to the final of the Canadian Open and the semifinals of the US Open.
Things haven’t quite gone to plan since, though, and Osaka even hinted at retirement after suffering an early exit at the Miami Open.
If Osaka were to follow through and retire from tennis, that could open the door for a Swiatek/Wiktorowski reunion…
Who else could Iga Swiatek turn to?
Wiktorowski might not be an option, but who else should Swiatek consider?
Well, the early favorite for the role, Piotr Wozniacki, has said he definitely won’t coach Swiatek, which rules him out of contention…
But if she wanted an experienced former player, there are several she could turn to.
Former US Open finalist Greg Rusedski revealed whether he would consider coaching Swiatek on the latest episode of his podcast.
“She has got to call me. You always want the player to call you, because then you get buy-in,” he said.
The 52-year-old didn’t confirm or deny his interest; he simply outlined the steps Swiatek should take if she wants him to coach her.
The Pole could also call Andy Murray, who expressed his interest in coaching Swiatek back in 2023.
“On the women’s side, I’d love to coach Swiatek,” he said.

If she wanted a more experienced coach, perhaps Juan Carlos Ferrero could be an option.
The Spaniard coached Alcaraz to his first five Grand Slams and the world number one ranking.
He is, however, currently employed by 21-year-old Spanish golfer Angel Ayora.
But surely Ferrero wouldn’t turn down the chance to work with a player of Swiatek’s calibre.
Swiatek has plenty of coaches to choose from, but only time will tell who will replace Fissette.
