Having an understanding of how Dortmund needs to be a lot more "calm" when it comes down to the last games would be the key thing to work on and it is not going to be easy. Bayern didn't tremble, they won the last game just like they suppose to and Mainz wasn't really a team that Dortmund should be having trouble against neither, losing to them was the most psychological loss I have ever seen, it wasn't due to their tactic, not their roster quality, not anything else, it was purely just because they were not ready for it and that's it.
This is why I honestly believe that we should see Dortmund work on the last weeks, how they could do that is beyond me, that's managers job, but they need to be more consistent on the last weeks to get the title.
How Borussia Dortmund who kept cool to beat Leipzig a week before the last matchweek, was unable to win Mainz at home has remained a very big surprise for me. I expected a better team performance from the Dortmund players.
This is the closest they've come to winning the German Bundesliga since they last won it in 2012 and now that they failed to win it, i think it'll be difficult to end Bayern Munich's dominance in the German league.
The Dortmund team was in very good form. And in such form, they can't even win at home against Mainz. This is very disappointing and sad. Dortmund's players should have performed more responsibly. The poor performance of Dortmund's defenders was the main reason for their defeat. Had Dortmund's defense been strong against Mainz, they could have won the match.
But I am very upset with the Dortmund management. Winning the title was never their goal. They will create players and earn money by selling players. Haaland was their main striker in the previous season. Had Haaland and Haller been in Dortmund's attack this season, Dortmund would have been able to win the title this season.
