Jannik Sinner said he “didn’t feel at ease” during the Australian Open in January and considered taking a break from tennis after he was sanctioned for two anti-doping violations.

The 23-year-old, who will return to action at Italian Open after short ban, ‘wasn’t in a very happy place’ before year’s first grand slam.

Jannik Sinner considered leaving tennis entirely earlier this year before he accepted a three-month ban in a settlement with the World Anti-Doping Agency
