Fired-up Novak Djokovic Sends Melbourne Warning, Naomi Osaka Bows Out Injured

A 'very hot-headed' Novak Djokovic produced a vintage display to join Carlos Alcaraz and Alexander Zverev in the Australian Open last 16 on Friday, but Naomi Osaka 's bid for a third Melbourne crown is over with injury.

Also on day six, women's defending champion Aryna Sabalenka 'pushed to the limit' to set up an intriguing showdown with teenage talent Mirra Andreeva.

Red-hot Coco Gauff was an emphatic winner once again to underline her title credentials.

Djokovic, who is chasing a record-extending 11th Melbourne title and historic 25th Grand Slam crown, is on a collision course with Alcaraz in the quarter-finals.

Both kept that tantalising prospect alive with ruthless victories.
