I don't see any interest in becoming champions in teams like Dortmund and Leipzig in the Bundesliga. Dortmund's main business is to produce talented players and sell them at high prices to other clubs, including Bayern Munich. If the management of Leipzig and Dortmund had tried to strengthen their team by investing some money, the rule of Bayern Munich in the Bundesliga would have been somewhat lost.
I dont agree with that , Dortmund just got no luck the last season and i would say if Haaland was injured many times they would be a real opponent for Munich.
Also the transfers they did now already shows that they planning to get the title in coming season and compete with Bayern Munich seriously.
About Leipzig they also have done well the last years and they just was unlucky too the last season.
My favorites for the coming season are Bayern Munich , Dortmund , Leipzig and Leverkusen.
