Novak is best in 2021

Well, Djokovic is ranked number one and has 3 major titles, so that's that for 2021 to date.

But if you instead asked "Best player since July" that's definitely NOT Djokovic. It's between Zverev and Medy. They've split a Gold, a Major and Masters 1000 while both beat Novak.

Since July, Novak has lost to Pablo Carreno Busta, Sasha Zverev, and Daniil Medvedev as well as losing, then defaulting in mixed doubles.

Time will tell if that's a hiccup or a trend, and why. Injury, fatigue, tension, age?
