It looks like Harry Kane would prefer to stay at Spurs for that reason and maybe it's okay for him not to win any titles as long as he's wearing a Spurs shirt. But sometimes if that's the case with other players, of course he has moved to another club a few seasons ago, but not with Harry Kane as if his soul is very much one with Spurs. But whatever decision he makes we have to appreciate it and if he starts to change his mind before the summer closes it will be better for his future to be able to win trophies with other clubs.
Whatever decision Harry Kane makes, of course, will be highly appreciated by all parties because he also thinks about the best for himself when he is in a team like Spurs. But if in case he would prefer to move to another team, I only hope he is still in the Premier League because the playing style of Harry Kane himself is more suitable to continue to be in the Premier League. Especially on teams that are often in the top four standings.
