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 Manchester 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.
With Benzema gone, Madrid needs a striker upfront that can benefit from Vinicius and Rodygo but I do think that Harry Kane is not a likely option at this time given his age (going to be 30 in a month's time). Madrid survived the years because they made very few squads changes in recent years. That said, a more likely option would be a young star who could give 4-5 years of service to the club. I respect Harry Kane but he should have left Tottenham when he had the chance. Aside from being a prolific player, Having trophies to your name is the icing on the cake and Harry Kane doesn't have that.
But I am really blind who can do that?
Although Harry Kane turned 30 years old, but his contribution as attacking would still remain consistent, considering that in Benzema he was still fairly tazam as an attacker until his 35th age, despite experiencing many injuries. I think Real Madrid also needs a fairly mature and mature player, so if composed of Rodygo and Vinicius will form a solid partner with Kane.
We are quite sorry for the potential of Kane who is fairly worthy of finding a title, but at the time not to have the opportunity at Tottenham.
