The 36-year-old Serbian had been indestructible on Wimbledon's Centre Court for a decade but finally met his match as he ran out of ideas to stop young gun Alcaraz from hurtling towards the title in the grasscourt major.
After the 20-year-old had broken for a 2-1 lead in the fifth set with a stupendous passing shot winner, Djokovic's racket felt the full force of his anger as he smashed it against the wooden net post to leave it in a mangled mess.
