When you've got to go, you've got to go and that was definitely the case for Novak Djokovic during his opening win over Roberto Carballes Baena at the Australian Open.
Djokovic ignored the umpire to take an early toilet break after just five games into the contest at 3-2 up. Shouting hello multiple times, he ran off down the tunnel to shouts of 'Novak' before a time violation was potentially set to be issued.
But he made it back in the 30 seconds required, a close shave for the Serbian.
