Mkhitaryan is not the only one to have exited the club this season. Dortmund have also been weakened by the exits of midfielder IIkay Gundogan to Manchester City and defender Mats Hummels to rivals Bayern Munich. Aubameyang and Marco Reus are two of the most important players remaining and this season a depleted Dortmund will certainly look upto Aubameyang to help them challenge for the Bundesliga title that Bayern have been winning for the past four seasons.
