World No.1 Jannik Sinner has hired former Novak Djokovic coaches Marco Panichi and Ulises Badio following the dismissal of his previous fitness coach and physiotherapist due to a doping scandal. Sinner tested positive for the steroid clostebol in March, but an independent tribunal cleared him of fault, attributing the contamination to an over-the-counter spray used by his physio, Giacomo Naldi. Despite criticism and suggestions of preferential treatment, Sinner maintained his innocence and subsequently replaced Naldi and trainer Umberto Ferrara. The new hires were confirmed via an Instagram post, and Panichi and Badio will travel with Sinner to upcoming tournaments. Sinner has recently celebrated notable victories, including winning the US Open and Australian Open titles in 2024.
