Sinner parts ways with coach Darren Cahill

Jannik Sinner, who is ranked second in the world, announced in a video shared on social media on Friday that he has parted ways with coach Darren Cahill. According to media reports, Magnus Norman is expected to take over from Cahill.

Norman, a former player who rose to world No. 2, took Robin Soderling into the top five and reached two French Open finals with him. He also guided Swiss player Stan Wawrinka to three Grand Slam titles. The 50-year-old Swedish coach will work alongside Italian Simone Vagnozzi, who joined Sinner's team in 2022, just as Cahill did.

In the video, Sinner thanked Cahill and said that he owes a great deal of his success as both a player and a person to him. Sinner said he will never forget these five seasons and that working together has been a privilege.

After winning his fifth Grand Slam title at Wimbledon this year, Sinner has been away from the court due to a knee injury. He is expected to return in December at the Six Kings Slam exhibition tournament in Saudi Arabia.

Cahill is an experienced coach who has guided four players to the world No. 1 ranking. He was expected to leave the team in 2025 but had one more year left on his contract. At Wimbledon, he said he would stay on until the end of 2026 and would talk about his future after that. Sinner's rise with Cahill was interrupted in 2025 by a three-month suspension, which followed two positive tests for trace amounts of clostebol in 2024. Sinner was found to bear no fault in the matter.

Alexander Zverev is confirmed to become world No. 1 at the end of 2026. Sinner, meanwhile, will not play in any of the remaining ATP tournaments this year.
