Novak Djokovic took aim at Centre Court spectators he claimed disrespected him during a straight-sets win over Holger Rune in the Wimbledon fourth round.
A last-16 tie with Rune had been expected to be Djokovic's biggest test since having surgery on a torn meniscus last month, but the 24-time grand slam winner eased into the quarter-finals with a 6-3 6-4 6-2 victory.
