Harry Kane's continuous stay at Tottenham isn't because he doesn't want to leave the North London club but because the club do not want to get rid of their most priced asset.
Last two summer transfer window ago, Manchester City were very serious in trying to bring him to the Etihad but was resisted by Tottenham who tried stalling the deal from going through by giving the the citizens conditions that was too difficult to be met. Kane should know that if there's anytime he can leave Tottenham, it's surely now.
For now it looks like Harry Kane is getting closer to leaving Tottenham because his agent or his father has made a fairly advanced approach with Bayern Munich. Levy will eventually let Harry Kane go and that will be the final drama of Bayern Munich signing. Bayern Munich has pretty good prospects for Harry Kane career next season because he can achieve many individual achievements if he joins Bayern Munich.
Tottenham has indeed been the longest team Harry Kane has defended in his career so it will be quite difficult to make that decision if he really has high loyalty to Tottenham. That was where the situation made his transfer to Bayern Munich never end. Even a tempting offer has been rejected by Tottenham in the two bids that have been made by Bayern Munich.
