Big news in the tennis world: after winning his first Wimbledon, the 'Carrot Kid' Jannik Sinner is shaking up his team again. Sinner just rehired Umberto Ferrara, his old fitness coach, who was part of his early rise but left after a doping controversy last year. With Ferrara back and Sinner dropping his previous fitness staff, is this a genius move for more Grand Slam glory, or could old issues resurface? What do you all think about this reunion? #Sports #Tennis #Sinner
