Tennis star Iga Swiatek breaks up with her coach, Tomasz Wiktorowski. The world number one writes on Instagram that it was a joint decision.
"Coach Wiktorowski joined my team when I was in great need of change and a new approach to my game," writes Swiatek, and continues:
"His experience, analytical and strategic attitude, and enormous knowledge of tennis helped us achieve things I could never have dreamed of just a few months after we started working together."
During the three years that Swiatek has been trained by Wiktorowski, she has won four of her five Grand Slam titles, and climbed to the top of the world rankings. At the Olympic Games in Paris last summer, she took a bronze medal.
