Firing Nuri Sahin was a good decision, now the question is who are they going to get instead of him. Because at this stage, there aren't that many greats left at free agency, so they will either get an interim until the end of the season, or they are going to get someone from a good club. If they get an interim, I am not really expecting them to get much better, while I agree Nuri Sahin wasn't that great, we are not dealing with something that could be replaced by an interim and made better neither, that makes no sense to me at all. This is why I believe that it would be smarter if we could see this become a bit more expensive.
What I mean by expensive is that if they could end up with a much better manager, who is already managing a team right now, they would have to pay a good fee, look at United, they paid 10 million to Sporting to get Amorim, maybe Dortmund would get someone cheaper of course, but they should look for someone who is good already.
