But Brandt equalized with a twice-deflected shot six minutes later, before former Gladbach player Thorgan Hazard crossed for him to head in the winner. "Wins like today's, when you really have to dig in, do you good," Brandt said.
Hazard had earlier struck the crossbar in the closest either side had come to scoring. There was a bad-tempered end to the game with visiting coach Marco Rose shown a red card for protesting. "It's just as frustrating as two weeks ago," Gladbach's Jonas Hofmann said, referring to his side's 1-0 defeat to Dortmund in the league. "It's bitter and hurts because there was a good chance."
Dortmund's win eases the pressure on coach Lucien Favre. The Swiss tactician, who appeared to injure himself while celebrating a goal, was under fire after claiming just two wins in the previous eight games across all competitions.
