Barcelona risk losing Alejandro Marqués to Italian giants Juventus.
Juve are pushing to sign the Venezuelan striker this month and would be willing to include young midfielder Matheus Pereira in their offer.
New contract talks between Marques and Barca have hit a stalemate, with the youngster's demands deemed too rich by management.
His current deal now has less than six months to run, meaning January will be the last time Barca have the chance to make something from his departure.
Marques is currently impressing with Javier García Pimienta's Barca B team.
