The 29-year-old got the better of Andy Murray, the man who usurped him to be crowned the men's top-ranked player at the tail end of 2016, in last week's Qatar Open final in Doha.
Serving for the match, Djokovic secured the title on his fourth match point, having squandered three in the second set when Murray astonishingly recovered from 5-4 down and 40-15 to win three games in a row and force, at that point, an unlikely deciding set.
Past year at the French Open, the Serb admitted he was lucky not to be disqualified in his quarterfinal against Tomas Berdych.
However, despite that loss Murray actually extended his lead at the top due to the nature of the rankings.
But, he has admitted, he came close to turning down the title when he was first informed via email during a training camp in Miami last month.More news: French police nab suspects in Kim Kardashian jewellery robbery
Before defeat to Novak Djokovic in the Qatar Open final, Murray had been on a 28-match winning streak and was the firm favourite to win the event down under.
"I had three or four match points in the second set, he turned it around and I thought: Wow!" "Playing all five matches in this tournament and then three hours against the No. 1, my biggest rival, and winning in a thrilling marathon match is something that definitely can serve as a positive incentive for what's coming up". "Obviously, I am disappointed not to win tonight, but I played pretty well the last couple of the matches".
Djokovic had looked out of sorts as he struggled to tame Spaniard Fernando Verdasco in Friday's semifinal and he started inconsistently again, also requiring treatment to a bleeding right thumb in the third game. "I would like to spend a lot of time at home with family and see my child, or children, growing up".
The Serb lost form during the second half of 2016, freely admitting that his motivation levels dropped after he finally completed the career Grand Slam at the French Open. The Serbian tennis player has a 25-11 career head to head record against the Scot. "A few of the players have been chatting to me about it and asking what do we call you", he added.
