A retired Italian tennis player has suggested that Jannik Sinner never wanted to get rid of fitness trainer Umberto Ferrara in the wake of his anti-doping case last year. The world No. 1 was found to have “bore no fault or negligence” after proving the tests were the result of contamination.

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.

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