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;
1. Harry Kane,
2. Son,
3. 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.
For the front line, Tottenham has many options and quality players, but this is not evenly distributed on all lines so that the team's performance does not only depend on a good front line.
I think this Tottenham team doesn't target to win they just play consistently to be in the top flight and so far it's been quite successful in my opinion, I think like that because I see there has never been a hard effort from the team to buy other star players to make this team stronger.
Now Harry Kane is likely to leave and Tottenham may not be able to find a suitable replacement and it is very possible that they will only rely on the players they have and that is likely to make the team even weaker up front.
