Novak Djokovic said he was "in the zone" and played a "perfect match" Friday to line up a blockbuster Australian Open final against his great rival Rafael Nadal.

"Today was a perfect match for me from the first to the last point," said the Serbian after destroying 28th seed Lucas Pouille 6-0, 6-2, 6-2 in just 83 minutes On Rod Laver Arena.

"I executed everything that I intended to and even more than I have expected," said the world number one after a flawless display put him into a first Melbourne decider since 2016.

"It is definitely one of the best matches I've ever had on this court, definitely," added Djokovic, who hit 24 winners and had just five unforced errors.

"Every professional athlete wants to be in the zone, where everything flows so effortlessly and you are executing automatically everything you are intending to execute," Djokovic said, explaining a sublime performance where he conceded no break point.

"You don't need to think too much. I guess you're driven by some force that takes over you and you feel divine, you feel like in a different dimension. It's quite an awesome feeling that we all try to reach and stay in."

Pouille was left powerless on the other side of the net.

"I was trying to find a solution, but couldn't find any," lamented the Frenchman.

Djokovic will face second seed Nadal, who he described as his "biggest rival," in a 53rd career meeting and eighth in the final of a Slam.

In 2012 the pair contested the longest Grand Slam final in terms of time at the Australian Open when Djokovic edged an epic battle 7-5 in the fifth set after 5hr 53min.

The Serb ran Pouille ragged so effectively that he dished out a dreaded 6-0 "bagel" in a first set that lasted just 21 minutes.

Pouille held his first service game of the second set to a huge ovation from the centre court fans, but it was an all-too brief respite.
