Dortmund's handing over the title to Bayern Munich shockingly on the final match week was unbelievable to me as well. However I don't think Dortmund board are mad at this situation too much. I mean Terzic wouldn't get sacked for this. Because Dortmund's main target in this season was never to win the Bundesliga title. Maybe they got too close to doing it thanks to Bayern Munich's making many mistakes. But this was going to be extra effort by Dortmund if they made it.
I believe they met the expectations for this season as usual. Terzic's management would be appreciated due to staying in the title race until the final moments as well. Now the board must be aiming to make as much profit as they can from Bellingham's transfer to Real Madrid. This is their main vision of team management in the end.
This was just similar to Manchester City and Arsenal in the EPL, from my observation Dortmund were determined and had a chance with talents and hard work but Bayern Munich had enough experience on winning titles especially the league title and they have proven that again this season as they snatched the title from Dortmund at the last minute.
In terms of conditions, I still think this is different, especially with Arsenal's condition, which was victorious at the beginning and mid-season, actually this is quite different, even though Dortmund is more painful because they gave up in the last match.
But on the other hand, of course, in this case, we are also aware that even though Bayern is still quite good in terms of performance under Tuchel's direction, they are Bayern who have always been champions, even though this season is a little different in its movement in winning trophies.
