Watch Denis Shapovalov fume at umpire after being banned from going to LOO in middle of match at Australian Open

CROSS-LEGGED Denis Shapovalov showed he has a strong bladder after a toilet argument with the umpire.

The Canadian, 21, was unhappy he was barred from using the loo at the start of the fifth set of his 3-6 6-3 6-2 4-6 6-4 four-hour win over Italian teenager Jannik Sinner.

Shapovalov raged to the official: “What do you mean I cannot go? Will you disqualify me? I have to pee.

“I’m going to p**s my pants. Ask the supervisor. I’ll p**s in a bottle instead.

“Are you allowing players not to p**? I don’t understand this rule.”

Shapovalov now plays Australian wild child Bernard Tomic, who benefited from Yuichi Sugita’s third-set retirement to progress.

First-round loser Benoit Paire labelled the event as “really s**t” and said organisers took players in hard quarantine “for idiots”.
