Novak Djokovic YELLS at his own coaching team as he struggles to keep his cool after missing EIGHT break points in the first set against Taylor Fritz… before he finally edges past the American in a tie-break

Novak Djokovic was furious with his own coaching team after failing to get their attention during the opening set of his Australian Open quarter-final against Taylor Fritz.

After taking the court in scorching heat in Melbourne, Djokovic missed multiple break points in a grueling first game that lasted 24 points, and then failed to convert three more break point opportunities in Fritz’s second service game.

The Serbian superstar became increasingly agitated as the set progressed after missing a total of eight break points, taking out his frustration on his team during one change of ends.

The 36-year-old was drinking water while trying to get the attention of those in his personal box by frantically waving his arm. Unnoticed after several seconds of waving, Djokovic threw his arm in the air in dismay and then shouted across, which eventually worked.

However, he was still far from happy and signaled his team to always look to him to help him beat Fritz in a grueling first set.

Eurosport commentator Patrick McEnroe joked: ‘You only had one job!’ after Djokovic was ignored by his team for almost half a minute.

Djokovic’s concerns were understandable as Fritz began to shift the momentum in the latter stages of the set and had two set points in the 12th game.

But Djokovic held firm and then delivered a typically strong performance in the tiebreak, making it 7-3.

It is not the first time Djokovic has failed to keep his cool during his run at the Australian Open, after being confronted by a heckler during his second round match against home favorite Alex Popyrin last week.

Having just dropped the second set, Djokovic became involved in a fiery argument with a spectator early in the third, repeatedly saying, “Say that to my face.”

After the match, he refused to hold back when reflecting on the incident and the general behavior of the fans.

‘Not the best atmosphere to play in, to be honest. “People were actually making noise throughout the match between the first and second serves,” he said.

“What really frustrated me is when someone bothers me in the crowd. I told him to say it to my face, but at that moment I didn’t have the courage.”

That incident seemed to spark Djokovic into life as he went on to win the next two sets, and his exchange with his own coaching team also seemed to ignite him as he eventually took the first set against Fritz.

Djokovic is again aiming to reach the semi-finals in Melbourne as he searches for his 11th title at the opening Grand Slam of the season.
