Arsenal and Barcelona agreed a deal to take Pierre-Emerick Aubameyang to the Camp Nou on deadline day, despite a strong warning from manager Xavi Hernandez.
Aubameyang flew into the Catalan capital on Monday in a surprise development to both clubs, whom are yet to formally confirm the transfer.
The Gabonese striker has suffered an alarming fall from grace in North London having been stripped of the club captaincy and ostracised by boss Mikel Arteta.
