I think the situation that made him feel at home in Tottenham is that he has a place in the hearts of the fans and the comfort that he gets in Tottenham makes him feel at home with Tottenham. But lately he has been heavily linked with big teams from the EPL who are interested in securing his services in the transfer window. I think other teams should be able to persuade him of the loyalty he has with Tottenham to accept the offer they are making.
indeed he has quite good qualities at his disposal and he can reach a trophy if he moves to another team. I even think that if he accepts an offer from Manchester United to move, then that's a pretty good choice for his next career.
I find him a hostage of his own contract that he signed with Spurs otherwise being a legend in the heart of Spurs fans is funny since he will be forgotten the moment he leave the team or retire without getting any single trophy and Conte wasn't joking when he said that the whole team and the management are dysfunctional.
Spurs being Spurs is something that start to hear often. Kane has to find another team to improve and boost his career. It is ridiculous to see him in the shadows of Tottenham..
