Winning trophies with Spurs have been a big dream for Tottenham and Harry Kane has spent many years with Spurs with high hopes of winning trophies. I think Harry Kane should consider Manchester Uniteds offer if he wants to win trophies because Tottenham are still not in a place to say they can win trophies not even in the next season.
Harry Kane is turning 30 this summer so i think if he wants to make a move to leave Tottenham, then it has to be after this season. Now that it is clear, that he will be without a title yet again with Tottenham i think it is very likely, that he is trying to go to another club now, where his chances of winning a big title are higher. I am not sure but i also think that Kane possibly does not want to go to another club within the English Premier League, because Tottenham will always be his club and he does not want to play for a direct competitor of the spurs.
Maybe Bayern Munich is really trying to get Harry Kane in this summer. It could be a good move for every party involved, if Kane is not to expensive.
