Speaking on the manager's sacking, Dortmund sporting director Lars Ricken told the club's website: "We value Nuri Sahin and his work very much, we hoped for a long-term collaboration and until the end, we had hoped that we could achieve a sporting turnaround together.
"After four defeats in a row, due to only one win in the last nine games and currently tenth in the Bundesliga table, we have unfortunately lost faith in being able to achieve our sporting goals in the current constellation. This decision hurts me personally, but it was unavoidable after the game in Bologna."
