Harry Kane is loyal to his team Tottenham, but still, we know any player will leave his team one day and for a 30-year-old player like Harry Kane this season is a good chance to leave Tottenham and join a better team to achieve whatever he wants, otherwise, he can't he this chance in the next season. Also, Tottenham can earn a good amount of money for selling this player from this deal.
I think right now it's a purely monetary issue and Tottenham are just trying to bargain for a big price for the player. Therefore, I think that Ken's transition is a matter of the near future. No wonder the leaders of Bavaria are going to England again.
