Not only was Novak Djokovic playing for the Australian Open title on Sunday, he was playing catch-up in the race to be crowned the 'GOAT' in men's tennis.
The number of Grand Slam titles is the most obvious and easiest metric for those who wish to determine - and not everyone does - which man is the Greatest Of All Time.
Serbia's Djokovic won in Melbourne to land an 18th major title, moving him two behind Rafael Nadal and Roger Federer's all-time leading tally of 20 Grand Slam singles victories.
Beating Russia's Daniil Medvedev for a ninth Australian Open title may prove to be pivotal in the race.
