The fight for the supremacy of the Grand Slams will live a new chapter in the Australian Open. But it won't be the only one battle between Novak Djokovic and Rafa Nadal in Melbourne in the absence of Roger Federer, since the Serbian and the Balearic will maintain the pulse for the number 1 of the world ranking.
To Nole's relief, his number 1 is not in danger no matter what happens in the first major of the season, since thanks to the ranking frozen by the pandemic, you will not lose points. Nor will he win them, since he is the current champion. This scenario makes your current income of 2,180 points over Nadal, is more than enough to leave Australian lands as leader and, consequently, that ends up surpassing Federer's record of weeks as number 1 in tennis history (310).
The second reason that Djokovic has secured the world title after the Australian Open is that Nadal can only add 1,640 points if he is proclaimed champion. That is, it would only add up the difference between the 2,000 champion points and the quarterfinals that he reached last year (360). In the event that the manacorense claimed his 21st Grand Slam title, would add 11,490 in the ranking, to 540 of Djokovic (12,030).
