Frankfurt, meanwhile, have failed to win any of their last seven league matches, with the success of their season now appearing to predominantly rest on winning the DFB-Pokal.
Dortmund, of course, have aspirations to win a major trophy themselves this season, as they attempt to hunt down Bayern at the summit and prevent them from winning an 11th consecutive German title.
BVB were the last team to stop the Bavarians from winning the Bundesliga when Jurgen Klopp guided them to successive titles between 2010 and 2012, with Edin Terzic's side looking like the most capable Dortmund team of ending over a decade of hurt at times this season.
However, with Bayern surprisingly dropping two points at home to Hoffenheim last weekend, Dortmund would have been kicking themselves by doing the exact same thing after playing out a pulsating 3-3 draw away to relegation-threatened Stuttgart.
The victory looked to be in the bag when Sebastien Haller and Donyell Malen provided the visitors with a two-goal cushion inside 33 minutes, especially when Konstantinos Mavropanos was given his marching orders six minutes later.
However, Stuttgart rallied to equalise through quickfire strikes from Tanguy Coulibaly and Josha Vagnoman, before Giovanni Reyna scored what appeared to be his third injury-time winner already this calendar year. Sensationally, though, there was room for more drama still as Silas claimed a point for his side in the seventh minute of added time.
Throwing away a two-goal lead in the midst of a title race is one thing, but to do so against 10 men is another matter altogether, and Terzic will be desperately hoping that his players can pick themselves back up against Frankfurt this weekend.
