It is obvious that there is a problem in Union Berlin. They played 11 matches and had 2 wins and 9 losses. They don't have a single draw so far. Union Berlin is at a level far from last year and since they are the last team in the league, the fault lies primarily with the coach. They were one of the strong teams in the Bundesliga and I'm sure they will start to recover soon.
Why hasn't the board fired Sébastien Bönig as head coach because I'm really bewildered, what have they accomplished this season other than dismal outcomes and frequent humiliation against opponents? I believe Union Berlin has the energy to battle back this season; they must give everything they have if they want to win games and improve their table position. They're at the bottom, which is devastating information for the club. However the fans will show their support in all rounds, atleast it will do some help and ginger the players.
AFAIK Union Berlin head coach is Urs Fischer, and I heard from local media that Urs Fischer has also now been relieved of his duties from that chair.
