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.
If Real Madrid seriously makes an offer to him, I think Kane is still possible to leave Tottenham. Since Real Madrid failed to sign Haaland or Mbappe, they may move their target to Harry Kane. They need a CF like Kane, there is not many options for a strong and top CF right now.
