Kane has scored at least 20 goals in the past four Premier League seasons, including netting 23 so far this campaign.
Chiellini said the England international deserved to be compared to Messi, Ronaldo and Neymar – widely regarded as the best three players in the world.
"Kane is now among the elite players in the world. Over the last years, with the goals he has scored, he has been on the level of the best," the Juve defender said, via the Mirror, ahead of his side's meeting with Tottenham in the Champions League on Tuesday.
