Novak Djokovic continued his pursuit of a 100th career title by dismantling Italian youngster Flavio Cobolli to reach the last 16 of the Shanghai Masters.
The 37-year-old Serb was sharp and clinical in a 6-1 6-2 win, which took little over an hour.
Cobolli, who grew up idolising the 24-time Grand Slam champion, could not cope with Djokovic's ability to anticipate the rallies and rarely miss a return.
As well as his unerring precision with clean groundstrokes from the baseline, Djokovic's high level ensured he conceded only seven points on serve.
Next, the world number four will face Russian Roman Safiullin for a place in the quarter-finals.
