I agree with your statement. Kane really did his best at Tottenham Hotspurs but then they are not a great team. Kane is a star player. Rumor has it that he has decided to move to Bayern. In my estimation, Bayern is a winning team and he would have to problem strengthening the team. Since the Bundesliga title belong to them as we already know, Kane wouldn't make any difference in the German league. Rather, what I want is to see is them advancing to the finals of the Champions league next season with Kane in the Squad. Would this happen, well let's wait till his move is confirmed.
It seems that Kane is serious about moving to Bayern, yesterday I saw the news that Kane is not considering other options than Bayern, and today there is fresh news that Kane is ready to boycott Tottenham to speed up this transfer. It seems that Kane is ready to threaten Levy that he will leave the club in a year as a free agent, if he doesn't let that transfer happen.
Kane understands what prospects he will have in Bayern, what he can achieve, he will have a real chance to become the German champion and he will also have a good chance to compete for the Champions League, so his desire to go to Bayern is understandable.
