Nick Kyrgios has doubled down on his criticism of Jannik Sinner, after the Wimbledon champion announced that he had rehired his former fitness coach who was involved in the Italian star’s doping case. Sinner recently parted ways with fitness coach Marco Panichi and physiotherapist Ulises Badio and re-appointed Umberto Ferrara, nearly a year after firing him following the investigation into the Italian’s positive tests for a banned substance. Kyrgios – who is a vocal critic of doping in tennis – lashed out at Sinner on social media platform X on Thursday morning. “He got the same doc back,” he wrote on X with a series of potato emojis. “We have been played ladies and gentlemen.”
