Djokovic was crushed by Sinner in last year's French Open and Wimbledon semifinals, but remains optimistic he can still pull off an upset. Are they (Sinner and Alcaraz) better right now than me and all the other guys? It has proved increasingly difficult with the emergence of Sinner and Alcaraz, who have shared every Slam title since then. Despite being odds-on favorite, Sinner said he was still learning from Djokovic and would not be underestimating him. I feel like every day, every time he plays, I can learn something about him, about Carlos, about all the other great, great players.
