The change of coach may make the team unstable at this time but I think it will only be a short-term challenge before they recruit a new coach, their previous coach managed to optimize every ability that the players have including young players as done by Klopp and also Edin Terzic, but we don't see that happening when Nuri Sain coaches, Even though we know , if their has been relying on the sale of young players to continue to provide stability to their finances, I think current their must able to get a coach who have tactical skills, strategy and also develop the talent of young players, so that they can still compete with other teams in the Bundesliga while also still being able to orbit talented young players who will be the source of the club income later.
It could even be more than that in my opinion, because after all a new coach needs time to adapt and maybe it is a long time for them to really understand the character of each player they have. But I hope Borussia Dortmund can be very lucky to be able to get a coach who can immediately show something positive, although I feel that it is also unlikely to happen. However, if they fail with their new coach, I also hope they don't decide too quickly to bring in a new coach. At least they also have to see how the process can be done, after all what is happening now I think is because of their own actions.
Although dortmund is not a financially strong team but actually they still have an attraction from good coach, but I don't know what makes them make nuri sahin as a coach when edin terzic resigned before, several names have been linked as a replacement for nuri sahin at this time, but among these names I don't hope if ten hag will become their coach after what we have seen happen at manchester united so far, right now I think they have to really choose the right coach even though it might not be able to bring an increase in position in the standings in the near future, but at least the new coach can bring changes in performance and also their game strategy, it cannot be denied that adaptation with a new coach certainly takes a lot of time, but I think with the squad they have now it should not be difficult for the new coach to bring dortmund to be better later.
It has not confirmed anything about the next coach of Dortmund and we can't undersnta the next coach in this team yet but as far as I know there are many coaches on the list to fill the palce of Nuri Sahin in Dortmund. They aer rich enogu to hire the best ocachs they can hire for this team.
Now it seems Niko Kovač is near to Dortmund more than the other coaches. Niko Kovač is a Crotian - German coach who as the experinace of wokring for Bayer Nmunich and Monaco, last time was worknig for Wolfsburg.
