The thing is first of all I know he is very loyal to his club. But it is certainly time to leave Tottenham. I am sure that if it was any other player than him they would have actually left Tottenham a long time ago.
This is a big problem for Kane, even though he must be aware that if the goal is trophies then Tottenham is not the right club.
Loyal is very good but actually it's a shame he's just very fierce as a top scorer but there's nothing more to make him shine even more. His current age is not young anymore and is about to turn 30 years old so if he really wants something more then Tottenham is not the right club but he has insisted even a long time ago when Manchester City really wanted his services.
