Cologne caretaker boss Stefan Ruthenbeck has signed a deal to remain as head coach until the end of the season.
Ruthenbeck took over at the Bundesliga's bottom club following the departure of Peter Stoger at the start of this month.
Cologne won for the first time in the league on Saturday at the 17th attempt, beating Wolfsburg 1-0.
"FC is my club. To be given the trust to do my job here makes me proud as a local of Cologne and it is a tremendous chance as a coach," Ruthenbeck told the club's official website.
"Together with my coaching staff we will do everything in our power to approach the next 17 league matches as if they were finals and to keep the dream alive of remaining in the Bundesliga."
