Novak Djokovic's major sponsor Head have admitted they "got ahead of themselves" after declaring the Serbian this year's Australian Open champion even before he took to the court for the tournament final.
The 2021 Australian Open men's singles final will begin at 7.30pm (AEDT) on Rod Laver Arena with Djokovic aiming to claim his 21st successive victory at the tournament and Medvedev hoping to win his first Grand Slam title.
Amid a chorus of boos, the protestors were lead out of the arena and the match swiftly continued.
Nearly all of Medvedev's strokes are registering faster average speeds, beginning with the serve, where Medvedev has attained both an average first serve speed (202.7km/h) and top speed (218.8km/h) nearly 10km/h hour faster than Djokovic.
It heralded a golden year where he won three of the four Grand Slam titles.
That would move him within two of the men's record of 20 shared by Roger Federer and Rafael Nadal.
But that's when Djokovic stepped up, and Medvedev stepped back. He never has won a match after dropping the first two sets.
Another reason to watch: These guys play somewhat similar styles.
"It's definitely my favourite Grand Slam, my most successful Grand Slam".
"Last but not least I would like to thank this court", an emotional Djokovic said at centre court.
Djokovic's been doing that sort of thing for years.
His 7-6 (7/5), 6-7 (4/7), 6-3, 6-0 victory was his first as a father after wife Jelena had given birth to Stefan three months earlier.
'I'm not going to stand here and hand it over to them, Mats, you know that very well.
While much was made of Medvedev's unshakeable demeanor ahead of Sunday's clash it was short-lived, as a fearless first-set stand that saw the Russian claw his way back from an early break eventually went begging to an unforced error that gave the set to the Serbian star, 7-5.
He defeated Murray for a fourth time in the championship match 6-1, 7-5, 7-6 (7/3).
Djokovic is seeking a ninth Australian Open trophy and 18th Grand Slam title overall.
"It's an incredible feeling, especially because of the fact that I managed to make history tonight and equal Roy Emerson's record of six Australian Opens", he said after winning his 11th Grand Slam crown to match Rod Laver and Bjorn Borg on the all-time list.
That quickly took effect and saw Medvedev "hit himself into a hole", as U.S. tennis legend Jim Courier put it, as the underdog struggled to find any answer for the masterclass facing him across the net.
Medvedev is trying to collect his first Grand Slam title. He enters Sunday on a 20-match winning streak.
Federer was dispatched in straight sets in the semi-final but 26-year-old Dominic Thiem gave Djokovic his hardest final battle since the Nadal epic in 2012.
Djokovic eventually fought back from two sets to one down to secure his 17th major 6-4, 4-6, 2-6, 6-3, 6-4.
"Obviously at this stage of my career, Grand Slams are the ones I value the most". I'm going to make them work their ass off for it!'
He was unable to train between matches, but grew fitter and stronger with every passing round.
The world No 1 put on his most convincing display against qualifier Aslan Karatsev in the semi-finals.
Former world number two Alex Corretja is expecting Novak Djokovic and Daniil Medvedev to "kill each other" in an intense Australian Open final on Sunday night (AEDT).
