Prior to this meeting with Jannik, Novak Djokovic has already lost two sets over the first four rounds of the tournament. He usually doesn't lose sets until the deeper portions of Grand Slam tournaments, but at the 2022 Wimbledon, he's lost one right in his very first match against Soon Woo Kwon in the opening round before winning in straight sets in the second and third rounds against Thanasi Kokkinakis and Miomir Kecmanovic, respectively. Then he dropped another one in the fourth round versus Tim van Rijthoven.

Novak Djokovic is human after all, but it still is surprising to see him look like one against Sinner. The Serbian has gone undefeated in his previous 25 Wimbledon matches heading into this showdown with Sinner. Still, it's hard to count Djokovic out even in the circumstance he's found himself in against Sinner. It's not that long ago when he battled back from two sets down in the finals of the 2021 French Open to defeat Stefanos Tsitsipas.

With 20 Grand Slam titles under his belt, Novak Djokovic just needs one more to break a tie with Roger Federer for a solo hold of the second spot on the all-time list and move just a slam away from leveling with leader Rafael Nadal.
