Thankfully Novak Djokovic doesn't lose very often, because when he does, he gets very angry.

The world number one showed the alternative side to the usually affable world number with some stomping racket abuse during last night's victory over Roberto Bautista Agut.

The top seed, who earlier in the tournament danced on court with a fan, was furious with himself after losing the second set to his Spanish opponent.

As he returned to his seat Djokovic stomped on his racket, with the force of the blow bending it completely out of shape. The Serb then discarded the racket over the back of the chairs he was sitting on.

Watch the incident below...

Djokovic would recover and go on to win the match 6-3 4-6 6-4 6-3 and reach the quarter-finals.

"I was upset with myself," he explained.

"I was frustrated with the fact from 4-2 and 15-40 I wasn't able to capitalise on those opportunities and lost five games in a row. I cannot allow myself to do that.

"It happens. I'm a player that shows emotions. Obviously at that moment it wasn't easy, but I managed to kind of regroup.

"The important thing is that I managed to find a way to win.

"Sometimes it goes in your favour, sometimes against you. Everybody's different.

"I'm not saying that this is a proper way to express your emotions. Sometimes you're not proud of what you do."
