No. 2 seed Novak Djokovic insists he is preparing for a tough round-of-16 clash as he won't take world No. 14 Diego Schwartzman for granted when they meet at the Australian Open. Djokovic, a record seven-time Australian Open champion, saw off Japan's Yoshihito Nishioka 6-3 6-2 6-2 to book a place in the round-of-16 at Melbourne Park.
The Serb was clinical on his serve, having hit 17 aces and won 54 of his 62 points to win second consecutive match without a break suffered. Meanwhile, Schwartzman saw off Djokovic's fellow compatriot Dusan Lajovic 6-2 6-3 7-6 (7) to make the Australian Open round-of-16 for the second time in his career.
Djokovic is well aware that Schwartzman is capable of doing damage on his return and he hopes to once again deliver a strong serving performance. "He's one of the quickest players on Tour," Djokovic said of Schwartzman, per the ATP Tour.
"Hopefully my serve can be as good as it was today, or at least close, because then I feel that I have a pretty good chance. I've got to be patient, but still aggressive."
