Gladbach took the lead from a Raffael corner which was not attacked at the near post and instead struck Daniel Davari on his thigh, ending up in the back of his own goal. It was the likeliest way for the Foals to take the lead too as they were otherwise struggling to get within sight of the Braunschweig goal.
Ter Stegen's blushes
The hosts weren't testing Marc-Andre ter Stegen either, although the German goalkeeper reacted well to save a Jan Hochscheidt's effort before a moment he will have nightmares about. As he appeared to want to shift a seemingly harmless backpass from Filip Daems onto his right foot, he contrived only to help the ball on into the back of the Foals' net.
It was a gift for Braunschweig and summed up the second half of the season for Gladbach so far. Lucien Favre's men tried to cover for ter Stegen's blushes by taking the game to Braunschweig, but despite their gallant efforts, they could no longer find a way through the Braunschweig defence, Max Kruse going the closest when he hit the post.
