Iga Swiatek has needed to make some big adjustments this year including with coach Wim Fissette.
Swiatek parted ways with her long-term coach Tomasz Wiktorowski, who is now working with Naomi Osaka, last year after the US Open.
After splitting from Wiktorowski, Swiatek announced that Fissette would be her new coach, the Belgian who has previously had success with Osaka, Kim Clijsters and Angelique Kerber.
However, after a relatively poor first half of the 2025 season, there were some calls for Swiatek to fire Fissette, and she has now reflected on some of her struggles this year.

Iga Swiatek explains why the start of her relationship with Wim Fissette was ‘tricky’
After failing to win Roland Garros for the first time in four years, Swiatek fell to her lowest ranking in four years.
Swiatek had not won a title in over a year before her fortunes started to change during the grass court season.
This included Swiatek winning the Wimbledon title, which had previously been her worst-performing Grand Slam tournament.
When speaking to The National about her season, Swiatek admitted that she made the mistake of having her expectations too high earlier on this year.
“With Wim, I think the start of our relationship was pretty tricky because he joined my team after my three perfect seasons,” said Swiatek. “So there was kind of no space to go up. Actually, winning Wimbledon was the only thing that I wasn’t able to do before.
“But yeah, usually you change coaches because something was going wrong and you have this boost, but this time it was a bit different. So I wanted to win because I knew that he’s a super experienced coach, he has such knowledge, and I just felt like his knowledge plus my experience and the way I play should give us something big.
“So the first part of the season, the expectations were a bit too high. I should have just focused on playing and that’s it.”
Iga Swiatek before Wimbledon vs after Wimbledon in 2025
There has been a dramatic improvement in Swiatek’s results since Wimbledon this year, as she has only lost four of her 31 matches since then.
This includes her winning three titles, with Swiatek triumphing at the Korea Open, the Cincinnati Open and Wimbledon.
Despite her vast improvement in recent times, Swiatek has actually regressed in terms of her record against top 10 players since Wimbledon, having only won two of her four matches against them.
| Iga Swiatek’s 2025 season | Swiatek before Wimbledon | Swiatek after and including Wimbledon |
| Win-loss Record | 35-11 (78.1%) | 27-4 (87.1%) |
| Titles | 0 | 3 (Wimbledon, Cincinnati Open, Korea Open) |
| Record vs top 10 players | 7-4 (63.6%) | 2-2 (50%) |
The most recent of those came at the WTA Finals, with Swiatek comfortably beating Madison Keys in her opening round-robin match.
Swiatek will look to obtain another top 10 win when she takes on Elena Rybakina in her second match at the WTA Finals in Riyadh.
