I know Tottenham is not performing well recently and mostly they lose points in the premier league and they lost the Champions League too but regarding Harry Kane, he is playing for Tottenham for a long time and he is an effective player there so I guess Tottenham will try to keep him but Kane can leave Tottenham because of having a better offer with a more salary from Manchester United, personally I hope Kane stays in Tottenham for another season.
Tottenham will always try to keep Harry Kane, he is the best striker in Tottenham. Previously, Harry Kane ever had a chance to move, he got a good offer from Man City. But he failed to move to Man City because Tottenham management didn't accept the offer of Man City and ensure Harry Kane that he will be better to stay. However, Harry Kane should have a dream to move to a bigger club and it is not impossible that he will try to leave Tottenham again in the next transfer window. I'm not sure whether he will move to Man United, Bayern Munich, or other top clubs but he seems to try again to move to a bigger club for the next season.
