Buying Aouar and binning Gundogan would be big improvement indeed. But cant see him binned, Aouar is signed as addition clearly rather than as replacement.
RMC Is pretty reliable source. Considering the price of at least €50m that means they will probably sell at €65m-€70m.
I don't think Pep would get rid of Gundogan as such, but I can see him leaving of his own accord. He talked about playing in Italy or Spain, and about the adventure of moving to a new country as one of the reasons he came here.
He's 29, has had 4 years here and 8 trophies...might be a good time for him to move if he wants a stint at Juventus or Milan.
