MELBOURNEL Not content with challenging Roger Federer and Rafael Nadal for the men's Grand Slams record, Novak Djokovic has Serena Williams and Margaret Court in his sights after claiming an astonishing ninth Australian Open title.

The world number one's bold statement followed Sunday's final, when he ended a turbulent tournament marked by a muscle injury and media attacks by humbling an in-form Daniil Medvedev.

Djokovic's 18th major crown placed him within striking distance of the men's record of 20, jointly held by Nadal, who lost in the quarter-finals, and Federer, who was absent through injury.

But the Serb also raised the prospect of a bigger goal: reaching the 23 held by Williams, and even the 24 won by Court straddling the amateur and Open era.

"Getting closer to maybe Roger's, Rafa's record, Serena, Margaret," said Djokovic, when asked about his goals and schedule for this year.

"Everyone has their own journey and their own way of making history. They've made history already. They made a tremendous mark in our sport.

"I think about winning more Slams and breaking records, of course.

And most of my attention and my energy from this day forward, until I retire from tennis, is going to be directed in majors, trying to win more major trophies."

Djokovic, 33, said he would play a slimmed-down schedule focusing on the majors, rather than the rankings, now he's guaranteed to surpass Federer's record of 310 weeks as world number one on March 8.
