Novak broke twice in the first set and once in the second to advance – 6-2, 6-4 in 78 minutes.
Nole won 85 per cent of his first-serve points and was 6/7 on net approaches.
“It was a satisfying performance against a young player that I have never played against, somebody who is in form,” Djokovic said.“I watched his match against Almagro who won a tournament last week, and he beat him comfortably. That deserves respect. We know each other well. We’ve practiced many times. I do see myself in him a little bit. We play a similar style. He’s a great fighter. For his age, he’s quite mature and mentally tough. Today was the first official match we’ve played against each other, I’m happy with my performance. It was a fun match to be part of.”
