Marco Reus scored 12 minutes from time as Borussia Dortmund beat Werder Bremen to secure a first victory under interim head coach Edin Terzic.
Lucien Favre was sacked as Dortmund boss after a 5-1 humbling at recently promoted Stuttgart on Sunday.
Reus converted on the rebound after his penalty was saved to make sure the visitors immediately bounced back.
Raphael Guerreiro had opened the scoring for Dortmund before Kevin Mohwald levelled in the first half.
Dortmund have put assistant coach Terzic and youth coaches Sebastian Geppert and Otto Addo in charge until the end of the season, with Terzic acting as the interim manager.
With striker Erling Braut Haaland injured, Terzic handed a first Bundesliga start to Youssoufa Moukoko, who became the youngest player to play a professional match in Germany last month.
The 16-year-old German forward saw an effort saved by Jiri Pavlenka and the Werder Bremen goalkeeper was also equal to Reus’ effort from the spot late on.
But the Germany international turned in at the second attempt to end Dortmund’s run of three games without a win in the German top flight.
They move up to fourth as a result, three points behind leaders Bayer Leverkusen, albeit having played a game more.
