Sinner looks back at his doping affair: "I've always tried to understand what I did wrong"

The case had caused quite a stir in the tennis world. Jannik Sinner, the current world number 1, was cleared after testing positive twice for Clostebol during Indian Wells last March.

However, the official decision was only made public in August, the day after the Italian's triumph in Cincinnati.

In recent hours, after winning the ATP Finals in Turin, Sinner has once again come clean about his doping affair.

He doesn't seem necessarily worried about a possible sanction, having seen the World Anti-Doping Agency appeal his acquittal last September.

"We've come through it three times successfully, and I'm convinced it will be the same for the fourth time," he assured. "I've always tried to understand what I did wrong or what I could have done better.

I spoke to my team, and we decided to do our best, because we couldn't do any more. My team pushed me a lot, there were days when I wasn't very well, nights when I didn't sleep well.

So you need a good combination of player and team. When I put on my cap, I don't think about what's going on off the court.

I've been lucky enough to have Simone, Darren and a lot of people around me who keep me stable. Thanks to that, we've continued to work every day like there's no tomorrow.

We've also improved over this period," he concluded.

The Italian has just completed an exceptional season with eight titles to his name and 70 victories. He has clearly come to terms with the media coverage of his doping affair.
