AS says Barca want that price if they are to part ways with the France international, a fee which would see them recoup the initial amount they paid Dortmund.
There is also an additional €40m of add-ons included in the current agreement between Barca and their German counterparts, but it is unclear whether any of those clauses have been activated yet.
Despite scoring 14 goals and providing eight assists during the campaign, the France international has found himself under scrutiny with questions over his attitude and fitness.
The player reportedly angered staff and players by missing a training session in November before turning up late to another a month later.
It it his off-the-pitch antics and his fitness troubles that has led to uncertainty over his future at the Nou Camp and reports in Spain suggest Liverpool have contacted the Spanish giants regarding his availability.
