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.

After the departures of Ferrara and Naldi, Sinner appointed fitness coach Marco Panichi and physiotherapist Ulises Badio in September 2004. However, he parted ways with the pair shortly before this year's Wimbledon. Sinner made his return to tennis at the Italian Open in May.
