The Belgium international says that he won't trade the England striker for any player in the world.
When asked what sort of price would Kane attract in the current transfer climate, Dembele told talkSPORT: "You know, that's very difficult to answer because a lot of things are considered in your price, not only your quality.
"Everyone who plays with Harry will confirm he is a phenomenon. He is a guy who every team in the world would like. Not only for his quality, and his sharpness. He's so hungry for the game and, not only that, his mentality in working for the team is [incredible].
"He is an unbelievable player so I can't imagine what kind of price [another team] would pay for him.
"He is a guy who doesn't believe in money deals. He just wants to have success in his career. He wants to play and have a good feeling where he is."
"At the moment I wouldn't change him for anyone, to be honest."
