I already said this before, but i really think that the chances of Borussia Dortmund to become Bundesliga champions this year were extremely high and i don't think that they will get such a big chance again in the next 5 years or so. As you already said, Bayern Munich is by far the strongest team of the Bundesliga and if they are able to at least reach like 85% of their maximum performance level, then they will win the Bundesliga no matter what the other clubs are doing. This year this was not the case and still Dortmund was not able to profit from that. Now Bayern should be alarmed again and take the next season more serious.
Why do you think that Dortmund has not that chance again to win the German League Title next year.
They getting better and better and every year they getting closer to Bayern Munich, and with Leipzig and Union Berlin there are now 2 more Teams for fight the Title.
Bayern Munich caused the problem themselves with kicking there coach out in an important time they have got a lot of important games.
I also think that Dortmund have no chance and desire to win the Bundesliga title. Because the main goal of Dortmund management is to do business. They don't want to win titles. Haaland was Dortmund's main player last season. He has played brilliantly throughout the season. Dortmund management made a lot of money by selling Haaland at the end of the season. Had Haalnd and Sébastien Haller been in Dortmund's squad this season, Dortmund had a great chance of winning the Bundesliga this season.
Sébastien Haller's performances this season have been outstanding. I think Dortmund will still make money by selling Sébastien Haller at the end of next season. If Dortmund's goal was to win the title, they would have wanted to strengthen the squad rather than sell the best players in their squad.
