Even if Dortmund had won, Bayern Munich would still have been champions. There's currently no team that can challenge Bayern Munich. Dortmund's squad quality isn't as good as Bayern's. I wanted Dortmund to win to add some excitement to the Bundesliga, but Dortmund didn't have the strength. Bayern Munich easily defeats any team in the Bundesliga whenever they want. I've followed the Bundesliga for years, and the team that challenges Bayern the most is Mainz. The other teams don't have enough strength or quality.
What I dislike about the German bundesliga is that any team that spring up and build a remarkable squad that can
challenge Bayern Munich dominance in the German bundesliga will be weakened the following season and Bayern Munich is also part of that, since they are more financially capable than the rest of other bundesliga teams.
Just look at how borussia dortmund and Bayern Leverkusen were weakened after they won the league during the time of klopp at borussia dortmund and xabi Alonso at Leverkusen, so we should not expect the German bundesliga to be a fair competition because the quality and financial might apart with Bayern Munich and the rest of other bundesliga teams is just too much for any of them to challenge Bayern Munich in the league title race.
