Kane has no strong mentality like walker. He will achieve nothing once he will always stay in totenham. Any players that wanna get achievements must leave from the totenham. This club now owns winner mentality. that's why totenham will never win anything.
It's only winning garbage trophy. As said by conte if all of totenham players didn't have good mentality to compete in the EPL. As you can see that how it was never achieving something on journey.

I dunno why totenham fans were seeing audi cup as a reliable cup while it's only friendly match trophy. There are two choices for harry kane at this moment. Now or never.
It's caused by the door to leave and go to the another club is not always open. Kane must consider if his age becomes even older. that was making him will be only wasting his time in totenham.
I will say if kane is having weak mentality if he will not leave from totenham in summer. he shall force totenham to decrease his release clause.
