The fact that Dortmund is at 10th place, is enough to fire Nuri Sahin to be fair. I am not really interested in any excuses or anything, Dortmund is not the type of team that should be getting anything good, we should be seeing how they are better. Think about it, this team was last years UCL finalists, and right now they are 10th on their league, that's just not acceptable at all. It was high time that they made a change and I understand why as well.
The biggest issue is, if the problem is not with Nuri Sahin and if anything is wrong with the players, then things could get a bit worse. If the players are the reason, then getting a new head coach won't make a big difference at all, it is just going to be something that will keep being a problem.
Dortmund's performance is really bad to be sincere. At this stage of the season, they shouldn’t be bad this way. I expected Dortmund to be one of the teams that will be at the top of the season, but up until now there have been no changes that look like they are going to be better this season. Although I don’t really know the main problem Dortmund is facing at this point, is it from the coach or from the players?
It's kind of something difficult for me to know, but since they have already decided to fire Nuri Suhin as their manager, maybe we will see positive changes if they hire a new manager. Although I know that it takes a long while before a new manager will be able to change a team's performance as everybody is expecting it, so I feel like Dortmund already messed up this season till next season again.
