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.
I know that there have been a little unlucky but they obviously cannot just depend on one player for doing all the work. It almost was light if Erling Haaland scores they win and unless he doesn't score they almost lose every time. I think Bayern Munich is obviously going to win the league title next season as well. Dortmund 2nd. Leipzig 3rd. And I really hope that Dortmund will be able to surprise me.
