Sinner reportedly picks Magnus Norman as coach to replace Darren Cahill from 2027

Reported appointment

Jannik Sinner has reportedly chosen Magnus Norman as his coach from the 2027 season, replacing Darren Cahill. The report comes from The Times, as cited by Adnkronos and Polsat Sport, while SRF News attributes the same claim to the New York Times. Norman would work alongside Simone Vagnozzi, who stays on the team. The articles do not include a statement from Sinner or his team, so the appointment rests on press reports.

Norman's record with Wawrinka

Norman coached Stan Wawrinka, and the articles credit him with three Grand Slam titles: the Australian Open in 2014, Roland Garros in 2015 and the US Open in 2016. Polsat Sport also notes that he guided Robin Söderling to the Roland Garros finals of 2009 and 2010. As a player, Norman was ranked world No. 2 by the ATP, reached the 2000 Roland Garros final and won 12 tournaments on the main tour, according to the same outlet. Wawrinka's career ends after the Swiss Indoors in Basel, which leaves Norman free for a new engagement, SRF News reports. Il Messaggero describes him as a coach who works on details and helps players cope with pressure in the matches that count most.

Sinner's season and ranking

Sinner, who is 25, has won five Grand Slam titles so far, according to SRF News and Der Tagesspiegel. He has not played a tournament since his Wimbledon victory, and SRF News reports ongoing knee problems that keep him out of action. Tagesspiegel goes further and says the injury rules him out for the rest of the year. In early October he announced the early end of his season. Sinner is still ranked first, but SRF News expects Alexander Zverev to take over the top spot shortly.

Cahill's exit and the return plan

Darren Cahill, the Australian who has coached Sinner, is leaving his post. Polsat Sport reports that Cahill retires after the 2026 season. Tagesspiegel reports that Sinner wants to attack again in the new year with a new coach. SRF News reports that Sinner hinted on Instagram at a start in the Six Kings Slam in Riyadh at the end of December. Il Messaggero places his comeback at that event, scheduled for 27 to 30 December.

What remains unconfirmed

The reports agree on the core claim but differ on details, including who first reported it and when Sinner will return. Until Sinner or his team confirm the change, the appointment remains a press report. The next concrete marker in the sources is the Six Kings Slam, scheduled for 27 to 30 December.
