Overview
- Sinner announced on Friday that he will conclude his coaching partnership with Darren Cahill at the end of the 2026 season and publicly thanked Cahill for five years of work.
- Multiple outlets report that former world number two Magnus Norman is set to step in as head coach while Simone Vagnozzi is expected to remain with the team to provide day‑to‑day continuity.
- Sinner has been sidelined since his July Wimbledon victory with a persistent knee problem and is targeting a late‑December return at the Six Kings Slam exhibition in Saudi Arabia.
- Because Sinner has chosen not to play the remaining ATP events this year, Alexander Zverev is all but guaranteed to finish 2026 as the year‑end world number one.
- Cahill guided Sinner from 2022 to five Grand Slam titles and major progress while Norman brings a track record of working with Stan Wawrinka and Robin Soderling, a change that could alter Sinner’s tactical and mental preparation under a new head coach.
