As we are talking about Harry Kane, I can also indicate that Real Madrid would be a good choice for him this summer. We are just making assumptions now of course as we don't even know if he is thinking of leaving even a bit now. He must be enjoying his game under Antonio Conte's great management. If Tottenham weren't able to bring the right manager for the team, I would say that Kane would absolutely leave. But things are different now. As they are going to compete even in the Champions League, he must be happy. On the other hand, a probable offer by Real Madrid might change his mind too.
He is in his peak level , 28 years old and counting ... if he want to leave the club it must be now or never and he likely ready to announce that he is going nowhere ... manchester city the one who rumored pretty close and interested to sign him already had haaland now , so yeah there is no better place to move though.
But still yeah , things pretty wild in football ... today you could say 'i'm staying and the next day you are at the new club'
