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.
