Nick Kyrgios was involved in furious exchanges with a fan, the umpire and his own coaching box in a heated Wimbledon men's singles final during which he twice used the F word in front of two future monarchs.
The Duke and Duchess of Cambridge had brought their eight-year-old son Prince George to Centre Court’s Royal Box for the showpiece final but that seemed to have no restraining effect on Kyrgios, particularly during a tense third set in which he became embroiled in a series of distracting arguments.
The Australian, who has already been fined twice during the tournament for his on-court behaviour, looked in control of his emotions while winning the first set 6-4 but things began to turn sour after Djokovic stormed back into the match to win the second set - and the match.
