After splitting with Darren Cahill, Jannik Sinner has been confirmed to work with Magnus Norman in the 2027 season.

Norman is one of the most respected coaches on the ATP Tour, mostly for his brilliant collaboration with Stan Wawrinka, which brought them three Grand Slam titles in the era of the ‘big three’.

Sinner’s 2026 was disrupted by a knee injury and he missed the entire second half of the season, so he will be hoping to hit the ground running with Norman in his team.

Mikael Tillström, who co-owns the Good to Great tennis academy along with Norman, has now revealed the key reason why Sinner has hired the Swede.

In a recent interview with Corriere dello Sport, Mikael Tillstrom suggested that Norman will help Sinner stay fit and healthy first and foremost.

Asked about Norman’s main goal with Sinner, Tillstrom said: “First of all, get him back to 100% fitness and then keep him healthy. I think the team is thinking about this above all today, because for me there is no doubt: as long as he was healthy, Sinner was the best player in the world.

“I don’t want to take anything away from Zverev, but this is the reality. I think the whole team, Magnus included, is focusing on this goal. A concept that ties in with another key word, longevity.

“The first few months will also be used to build understanding and identify new work habits. Now Magnus and Jannik will have to get to know each other, understand each other and build new habits together. One aspect that I think will be particularly important is longevity.”

Sinner has not confirmed which tournaments he will play in the first part of the 2027 season, but he is expected to play the Australian Open as his first event.

After that, he will likely play tournaments in the Middle East, such as the Qatar Open, before heading to the Sunshine Double of Indian Wells and the Miami Open.

The Italian will need to hit the ground running with Norman as his coach as he is defending plenty of points in the opening three months of the season.

In 2025, he reached the Australian Open final and won both Indian Wells and the Miami Open, so he will need to match those results in order to get keep chasing Zverev as the world No 1.

There are currently 1400 ranking points splitting Sinner and Zverev, although that will very likely change as the German progresses through the ATP Finals.
