If Harry Kane wants to win the Champions League title, he will probably choose the Bayern Munich team. Because Bayern Munich can dominate more than Manchester United in the Champions League. However, Manchester United is a strong enough team. Bayern Munich and United are not weak teams. But first Harry Kane should be without Tottenham. However, since Harry Kane has played in the Premier League for a long time, Harry Kane could probably adapt quickly to any Premier League team.
harry kane is bayern's main target at the moment, and I'm quite optimistic that harry kane will choose bayern over manchester united because it's true as you say, bayern is a much better team than MU at the moment. btw there is news that says that when harry kane moved, dusan vlahovic was tottenham's target as a replacement for kane, I think vlahovic is quite suitable to play for tottenham.
I have heard rumors that Bayern Munich and their coach Tuchel are keen to keep Harry Kane on next season. They will try their best to bring Harry Kane to Munich. At the same time, Bayern Munich management will probably decide to sell Sadio Mane. Because Sadio Mane's performance with Bayern Munich was not good. He could not be a worthy replacement for Lewandowski. Mane does not have the ability to score a lot of goals. And so Bayern Munich targets Harry Kane. Kane can score a lot of goals. And getting Kane will make Bayern Munich's attack even stronger. It will be easy for Bayern Munich to dominate the Bundesliga and Champions League.
