The 33-year-old gave the striker a jarring welcome to international football when he crashed into the forward during a friendly between Italy and England in March 2015.
Kane spoke of the incident during his pre-match press conference, but Chiellini has admitted that he cannot recall the moment.
"Kane said I made a rough challenge on him once? I don't remember, it could be the case, but it wasn't on purpose," the defender told reporters during a press conference.
"He's an extraordinary forward as his statistics from the last year show. He's a complete forward who plays for the team. In my opinion he was already one of the best strikers and people were already talking about him then. I think I was a good judge."
The two players are expected to come face to face again in Tuesday's Champions League last-16 tie in Turin.
