Top two players in men’s tennis, Novak Djokovic and Daniil Medvedev, will vie for the 2021 US Open title on Sunday.

Serbian Djokovic eliminated Germany’s Alexander Zverev in the semifinal in New York on Friday night, with the sets of 4-6, 6-2, 6-4, 4-6, 6-2 to reach the singles final.

Djokovic, 34, equaled Swiss legendary player Roger Federer’s record with his 31st Grand Slam final. He is eyeing his 21st Grand Slam title.

In 30 Grand Slam finals, Djokovic has won 20, including nine Australian Open, two French Open, six Wimbledon and three US Open titles.

If Djokovic wins the US Open again, he could make history as the player with the most Grand Slam titles.
