Australian Open 2021: Novak Djokovic ends Aslan Karatsev's fairytale run to claim place in final

Defending champion Novak Djokovic has declared himself fighting fit for the Australian Open final, after ending the incredible run of Russian qualifier Aslan Karatsev with his "best match" of the tournament.

The Serbian world No.1 eased into his ninth decider at Melbourne Park with a 6-3 6-4 6-2 win under the lights at Rod Laver Arena, and will battle either Stefanos Tsitsipas or Daniil Medvedev for the title.

Djokovic's tournament appeared on a knife edge, when he suffered an abdominal injury during his third-round match against Taylor Fritz less than a week ago.

Yet he has put that aside and will have two days off to recover before Sunday's final.

"This is the best I felt during the entire tournament," he says. "Felt great, I could swing through the ball, no pain, just best match so far.

"It came at the right time and I'm thrilled to feel this way. Recovery is priority right now.

"I'm feeling the ball well, I'm playing well, I had enough matchplay, enough practice, so right now, it's just gathering all the necessary energy for the most important match of the Australian Open."

Djokovic has never failed to win the tournament after making the semi-finals and he will be heavily favoured to claim a record-extending ninth title at his favourite Slam on Sunday.

While Karatsev would have been regarded one of Djokovic's more unlikely semi-final opponents, the world No.114 put up a decent show, as fans returned to Melbourne Park following a five-day lockdown.

He broke Djokovic twice in the match and came back from 5-1 down in the second set to briefly rattle the Serb.

Karatsev saved two set points as Djokovic served at 5-4 and swung freely to prise two break points from the champion.

Djokovic fired two huge serves to cancel the threats, before sealing the set and taking the momentum into the third, as he broke Karatsev in the opening game.

Karatsev rallied again to level to 2-2, but a long tournament appeared to take its toll, as Djokovic raced away and sealed the match with an ace.

"We need to give him a hand, huge congratulations to him," Djokovic says of the 27-year-old Karatsev, who reached the main draw of a major for the first time, after failing to qualify at nine previous Grand Slams.

"On his debut, he reached semi-finals... I don't think it's ever happened in the history of tennis, so well done to him. He played a great tournament."
