AUSSIE OPEN TENNIS: YOU CANNOT BE KYRGIOS

Pundit Nick offers to 'go all WWE' on Novak heckler

- YASMIN SYED

NOVAK DJOKOVIC accused an Australian Open heckler of "crossing the line" during his second-round win over Alexei Popyrin yesterday.

And pal Nick Kyrgios threatened to "go all WWE" to sort out the unruly spectator.

Djokovic survived another tough test in Melbourne - three days after he played a four-hour-and-two-minute thriller in the first round.

The defending champion dropped the second set and saved four set points in the third before storming back to beat Australian Popyrin 6-3 4-6 7-66-3.
