Sinner-Alcaraz hurdle will be difficult to overcome: Djokovic
Novak Djokovic said it will be very difficult for him in the future to overcome the hurdle of Jannik Sinner and Carlos Alcaraz in the best-of-five on Grand Slams. "I'm happy with my level of tennis...it's just the physicality of it," the 38-year-old added, noting it's too soon to confirm whether he'll play a full Grand Slam season next year.
