Jannik Sinner has reappointed fitness coach Umberto Ferrara to his coaching team having previously dropped Ferrara during Sinner’s recent doping suspension.

Wimbledon champion Jannik Sinner has rehired Umberto Ferrara as his fitness coach nearly a year after firing him for his role in the top-ranked player’s doping case.

Yesterday, Jannik Sinner reunited with his old fitness trainer Umberta Ferrara, after the pair split at the end of last year due to Ferrara being involved with the Italian's controversial positive doping test.
