Former Arsenal striker Pierre-Emerick Aubameyang is already facing a tough moment in Barcelona despite barely getting his foot in the door with the Spanish club.
There are still details to be ironed with the deal and technically he remains a free agent while the Catalan giants attempt to register Aubameyang with La Liga, with Arsenal allowing him to essentially leave the club on a free transfer by cutting short his deal in north London.
It is a familiar problem for Barcelona. Sergio Aguero was signed in the summer but was unable to play for weeks with the club unable to register him due to financial restrictions.
