Barcelona risk losing defensive pair Martin Montoya and Marc Bartra.
Fullback Montoya is already a member of the full Spain squad and a target for AS Roma, while Bolton Wanderers, Blackburn Rovers and Tottenham tried for centre-half Bartra over the summer.
Both players had agreed terms at the end of last season, but neither player put pen to paper and Sport says their situation has changed.
Barca's original terms remain on the table, but far superior offers are arriving from abroad and there's belief inside the club that both players may skip out on the Nou Camp.
