I did not expect this decision. But if Dieter Hecking has the confidence to coach again and gets the team to avoid relegation? Why not? It is worth a try.
But I do not suspect that the dismissal of Markus Weinzierl was planned. Perhaps Hecking was also questioned from the board members and he had to take on the entire responsibility.
I don't know but for me such moves where a sports director is basically firing his coach in order to become the coach himself always has a kind of a bitter taste to me. Even though on paper the director of sports has obviously more power i still think that the position of coach is way more attractive to most people because as a coach you are way more in the spotlight of the media. Maybe it is different in this case because Dieter Hecking already had several stations as head coach and i doubt that he just wanted to be coach to get some attention again as i don't think that he even wants to have attention anymore. So far the change was successful as FCN finally have won a game again.
