“His experience, analytical and strategic attitude and enormous knowledge about tennis helped us to achieve things I’ve never dreamed of only a few months after we started working together.”
Swiatek says she has held “first talks” with prospective new coaches and will take a “couple of weeks” to start work with her next appointment.
She is not playing at the ongoing China Open having withdrawn beforehand because of “personal matters”.
The 23-year-old won the French Open and US Open during her opening season with Wiktorowski.
During 2022, Swiatek embarked on a 37-match winning run – the longest streak by a woman this century.
The Pole won a fifth Grand Slam – her fourth with Wiktorowski – at Roland Garros in June.
But Swiatek was disappointed with her hard-court performances this season, exiting the Australian Open in the third round and the US Open at the quarter-final stage.
