Although Mohamed Salah scored for Jurgen Klopp's side during the first half, Kane grabbed a brace while Heung Son-Min and Dele Alli also got their names on the score sheet to complete the rout for Spurs.
"Everybody is talking about world class, not world class," Henry said of Kane.
"For me it doesn't really matter. What he has is people fear him. Lovren, that was raw fear."
The win marked the first time that Spurs have defeated Liverpool since Mauricio Pochettino was appointed as manager and it leaves Liverpool in ninth position on the League standings with 13 points from nine fixtures while Spurs are in third position with 20 points from nine games.
