Iga Swiatek, the current world No. 1 in women's tennis, has appointed Belgian coach Wim Fissette as her new head coach, following her split with Tomasz Wiktorowski. Fissette is renowned for his work with several former World No. 1 players, including Kim Clijsters, Victoria Azarenka, and Naomi Osaka, and has a track record of guiding players to Grand Slam successes. This significant coaching change comes as Swiatek prepares for the WTA Finals in Riyadh, Saudi Arabia, and aims to improve her performance on hard courts. Swiatek has expressed excitement about the new partnership, emphasizing a long-term career strategy. The decision follows a series of impressive achievements under Wiktorowski, including four Grand Slam titles, and Swiatek aims to leverage Fissette's vast experience to continue her success and address recent performance dips.
