I doubt he’ll get to the number 25 at this rate except both Sinners and Alcaraz get injured or eliminated early in whichever of the grand slams he’s participating in, and that’s because Djokovic is now only participating in grand slams, and not participating in other ATP 500 and ATP 1000 events, it’s very tough to remain sharp if he’s not participating in those events and just head into grand slams, I understand that class is permanent and can not be bought, but he really does need to spend more time on the court, not just grand slams, even if it is a couple of ATP 250 events for real time matches not just practice.
