Overview
- The split with his father, Apostolos, was announced on the eve of Wimbledon after a return to father-coaching in July 2025, and Stefanos said he does not expect them to work together again.
- Tsitsipas named Thomas Perrin of the Mouratoglou Academy as his new coach and said Patrick Mouratoglou will supervise the team and attend tournaments when available.
- He described the Perrin/Mouratoglou arrangement as a solution committed through the end of 2026 with an option to continue beyond the season.
- The change follows a run of poor results for the 27-year-old, including a slide to around world No. 87 and a debilitating back problem at Wimbledon 2025 that has affected his form.
- The move gives Tsitsipas more autonomy over decisions and could reshape his preparation for Wimbledon and the rest of the year while Apostolos shifts focus toward coaching younger players.
