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.
We could see a totally different ranking next year, you never know, I don't really think Union Berling will be as strong as they were this season, we all saw their performance drop in the last matches of the league, I would count them out of the race of Bundesliga from now, they probably going to end up out of the top 4.
