Granada's on-loan defender Allan Nyom and Valencia right-back Joao Pereira have both reportedly emerged as transfer targets for Barcelona.
As it stands, Barca are under transfer embargo until January 2016, but it is understood that the club could exploit a loophole that allows for the signings of players from the same division.
According to Mundo Deportivo, Nyom, who is currently on loan at Granada from Udinese, has emerged as the leading target, while out-of-favour Valencia defender Pereira is also seen as a viable option.
Barca's current first-choice right-back Dani Alves is out of contract at the end of the season, while back-up Douglas has failed to impress since arriving in the summer.
Martin Montoya, meanwhile, looks certain to leave Camp Nou in January, rendering Luis Enrique's side short on the right side of defence.
