Despite their transfer ban, the Catalans hope to be able to call upon the Turkey midfielder in La Liga and the Copa del Rey after losing Rafinha to a serious injury last week.
Barcelona has asked FIFA for permission to play summer signing Arda Turan following the injury to Rafinha, but the midfielder's agent says he is "not optimistic" the club will receive an affirmative answer.
Barca was banned from registering new players by FIFA in 2015 due to irregularities in the signing of young players for their La Masia academy, but the Catalan club still brought in Aleix Vidal and Turan in the summer with a view to handing the pair their debuts in January.
