Harry Kane seems to be the target for many clubs this coming summer, certainly if Harry Kane leaves it will be a big blow to Spurs losing their best player in the team. With Manchester United also interested in Harry Kane whoever gets him in the end will be so lucky but I doubt Harry Kane will be willing to leave the EPL anytime soon.
Of course, Harry Kane is a top striker but he only plays in Tottenham. His contract with Tottenham will expire in 2024, and he seems to have the intention to leave Tottenham. So, it makes sense if many big clubs target him, the chance to sign him looks quite good. However, it won't be easy to sign him because Tottenham must ask big money for the transfer fees. I assume Tottenham wants big money above €100m for Kane. Only rich clubs have the capability to sign him. I think Real Madrid or Bayern Munich are 2 top clubs that are very possible to sign him. Man United looks not have enough money to sign Harry Kane.

There have always been opportunities for Kane to leave but his condition has remained until now and for now I think it will be the same as before. Even though a lot of people want him but Tottenham have always been able to keep Kane and when he is currently staying at Tottenham then I don't think he will get anything and Kane has to be aware of that.
