Courtois is relaxed about trying to stop Kane, the striker who scored twice in Tottenham's 5-3 victory against Chelsea at White Hart Lane on New Year's Day.
"You try and analyse what teams and strikers are like more and more by watching videos," Courtois said.
"But football is football and every game is different. Every time they come in front of you it can be different." Asked if he knew how Kane liked to finish, Courtois replied: "Yeah, I know it, but I don't have to say it now."
