Tottenham management has no desire to win the title. They are not interested in spending money and buying players. Every season they depend solely on the performances of Kane and Son. So Harry Kane will never win the title with this team.
Bayern Munich is the best team in the Bundesliga. The team also has the potential to dominate the Champions League. If harry kane can perform well with this team he will easily win the Bundesliga. At the same time, there is a possibility of winning the Champions League title. And so Harry Kane should join Bayern Munich.
Totenham has quality players. I mean they spent to buy players unlike what you said. Just check the front line of Totenham squad. They have;
Harry Kane,
Son,
Richardson.
These are quality players that can get any amount of goals to give a team title win. But I don't know what to say about Totenham. Ot could be that the management is the problem.
