The two parties have already reached an agreement and Barcelona have found a formula to sign the Arsenal striker on loan, regardless of whether Ousmane Dembele leaves the club in this window or stays until the summer.
Barcelona's striker search
Barcelona were in search of a striker to strengthen their attack, with Alvaro Morata being their main target in this January transfer window.
Juventus were initially reluctant to part ways with the Spain international, but their stance changed after signing Dusan Vlahovic from Fiorentina.
However, Barcelona couldn't meet Atletico Madrid's demands, as Los Rojiblancos did not seem willing to allow Morata join their direct rivals in the chase to secure Champions League football.
Hence, Barcelona set their sights on Aubameyang and entered into talks with the Gunners and the striker's agent just a few days ago.
There are some details which need to be finalised, but Barcelona have made sure that there is enough space in their wage cap to be able to register Aubameyang.
