Bayern Munich this season is going to try for the Champions League but this time I think unlike the last season Tuchel can give more stability to Bayern Munich on the other hand this Drtmound lost their key player and they can't race with Bayern Munich and make a problem for them.
Also if they hire Kane Bayern Munich is going to be even more dangerous.
I already said this before, but i am pretty sure that in the next 5 years or so Borussia Dortmund will not get such a big chance to become Bundesliga champion again as they had this year. The last season of Bayern Munich in the Bundesliga was probably their worst in at least 10 years and Dortmund had it in their own hands to become champion not only once but multiple times.
Now Bayern is heavily rebuilding their squad and of course it is also a possibility that Bayern is not doing well again in the Bundesliga, but even then i think that clubs like Bayern Leverkusen and also RB Leipzig are at least at the same level as Borussia Dortmund at the moment in terms of the quality of the squad.
