U.S. Open champion Jannik Sinner has introduced a new fitness coach and physiotherapist to his team after firing his previous staff members because of a doping case.

Jannik Sinner roped in Marco Panichi and Ulises Badio after parting ways with Giacomo Naldi and Umberto Ferrara. The World No.1 recently won the US Open after beating Taylor Fritz in the final.

Italian tennis star Jannik Sinner is currently facing a controversy that has stirred discussions within the sports community. But what exactly happened to Jannik Sinner? Fans are eager to uncover the truth behind the doping allegations,

Doping Agency has yet to decide whether to appeal the decision to exonerate U.S. Open champion Jannik Sinner of blame for his positive steroid tests, and has another three weeks to do so.

Sinner had explained that the slight traces of clostebol had originated from a spray used by a member of his staff to treat a cut finger.

But a second axed Djokovic coach was also in the photo - the Serb's ex-physiotherapist Ulises Badio, who is also joining Sinner's corner. It comes after Sinner parted ways with his old fitness trainer and physio because of their roles in his doping case.
