Dembele was forced off in the first half of Barcelona's narrow 2-1 victory over Getafe last weekend.
He has since had successful hamstring surgery in Finland, with reports claiming that the France international would be sidelined for three and a half months.
Now, however, Aubameyang has revealed in an interview with 'RMC' that Dembele is hoping for a faster recovery.
The Borussia Dortmund striker said" "I spoke with him, and he told me that he would be back in two months."
Barcelona certainly won't want to rush their big-money signing back into contention for selection, but Dembele appears determined to recover as soon as possible so he can return to action at the Nou Camp.
