I also did not find a lot of news about the team that was interested in Harry Kane, I only read the news that Harry Kane would move to Mancheseter United, besides that I did not find another team from my search.
The thing that might happen is Anceloti taking Kane to strengthen his squad, because if you think back who deserves to replace Benzema? After his departure. That is also if Real Madrid focus on his front line as a reliable attacker, but I have not found Real Madrid have a list of spending for persistent attacking players.
Kane has two options regarding his future, that is moving to Manchester United or playing for Real Madrid in La Liga. Kane will not have many guarantees of winning the title with Manchester United next season, but if he chooses Real Madrid then he might win it.
Kane is suitable as a successor to Benzema at Real Madrid, of course because Kane has a hunger to score goals. It's true that Real Madrid rarely sign players as old as Kane, but Kane should be a good short-term option because Real Madrid need a striker. But maybe, Real Madrid will also try to approach some other strikers who are younger than Kane.
