World No 1 Novak Djokovic continued his perfect start to the season with victory against Malek Jaziri at the Dubai Duty Free Tennis Championships on Monday.
Djokovic is yet to lose a match in 2020 having led Serbia to victory in the inaugural ATP Cup team event in Australia followed by his eighth crown in Melbourne.
He made it 14-0 this year following a straightforward 6-1 6-2 victory over Tunisian Jaziri in exactly an hour.
The 32-year-old is chasing his fifth title in Dubai and his first since 2013.
"It's a great way to start out the tournament," said Djokovic. "As I've said in the press conference prior to the tournament, I miss playing here. I really enjoy it. I enjoy night sessions, I think I've done everything as well as I imagined it to be for the first match.
"Of course, there's things that always can be improved, things that can be better. But I have to be satisfied with the performance."

Karen Khachanov was tested in the early stages of his opening match, before charging to a 7-6 (7-2) 6-1 victory against Mikhail Kukushkin.
Khachanov advances to a second-round encounter against wild card Prajnesh Gunneswaran or Austrian qualifier Dennis Novak.
