Novak Djokovic was involved in a controversial moment during his quarter-final victory over Taylor Fritz.
He looked frustrated as the audience cheered his double-fault in the third set, prompting a furious reaction.
Djokovic confronted the umpire, asking him why he was not taking measures to shut the crowd up.
He shouted: “What are you gonna do? What are you gonna do? Just ‘thank you, please’.”
The umpire responded: “I just said when both players are ready, stop shouting. I just said it. It’s not going to help, Novak.”
