The defeat means Dortmund are 13th and must get a result against Shakhtar Donetsk in their final league phase game to have the chance to qualify automatically for the knockouts. For the first time in the competition, the German side have lost multiple games after scoring the opening goal.

Nuri Sahin enjoyed a stellar career as a player at Borussia Dortmund, but his tenure as manager of the black and yellow has been mediocre at best. Friday's loss at Eintracht Frankfurt only emboldened fans of the German club to call for a change in leadership for the squad.

Borussia Dortmund fired coach Nuri Sahin on Wednesday, a day after its 2-1 loss to Bologna in the Champions League. The defeat extended Dortmund’s losing streak to four games since the new year and dropped last season’s Champions League runner-up to 13th in the 36-team standings.
