After the Klopp era ended at Dortmund there was no coach who was able to make Dortmund better, until in the end Edin Terzic was actually able to make Dortmund have hope again in the competition for champions in the league, but unfortunately Edin Terzic position as coach did not last long after he decided to step down from his position last season, I think with Nuri Sahin as coach this season we can't expect too much from Dortmund because he doesn't have the ability to formulate game strategies the same as when he was still coaching the previous Turkish team, so far Dortmund performance is in good condition. bad so it will be difficult for them to compete in the race for the title this season, especially since other Bundesliga teams have experienced significant improvements in their performance, to be honest, for this season I personally doubt that Nuri Sahin will be able to make Dortmund better than what performed by Edin Terzic last season.
Nuri Sahin still has a lot of time to make Dortmund better because he is also a coach who has experience in building a team even though he used to be in Turkey and not in a German team. However, the current condition will not be so difficult for Dortmund to compete because Bayern Munich has also been handled by a new coach and Leverkusen will also find it difficult to repeat their previous achievements in the Bundesliga. You may doubt Dortmund for the two matches they have played, but you should not be surprised when Dortmund can rise again in the next matches in the Bundesliga.
