A furious Novak Djokovic took out his frustration with his racket in emphatic fashion during his Australian Open quarter-final with Alexander Zverev.
The world number one could not contain his anger midway through the crucial third set as he obliterated his racket on Rod Laver Arena as Zverev watched on.
Trailing to the German sixth seed at the time, the explosion of emotion appeared to help settle Djokovic as he roared back in stunning fashion to break his opponent twice and take the set.
In stark contrast, Zverev's intensity dropped considerably after assuming the early lead in the set having taken the opener on a tense tie-break.
After a botched return at deuce with Zverev leading 3-1 in the second set, Djokovic smashed his racket repeatedly in fury.
"Wow! He's been harnessing that for a while," said Eurosport commentator Chris Bradnam.

"It's going to cost him! It would have cost him a lot more had he done that at Wimbledon."
"Yep, it's a shame, it's no good to anybody that," added Frew McMillan.
"It might be a nice souvenir for one of the ball kids."
There followed a delay as a ball kid was called by the umpire to run on and clean up the mess with a dustpan and brush.
In bizarre scenes, both players had to stand and watch the ball kid clean the court.
"It is absolutely smashed to smithereens!" said Bradnam of the debris from Djokovic's racket. "It's everywhere!"
