Barcelona are eyeing Arsenal fullback Nacho Monreal.
Having secured Jordi Alba to a new deal in the last 24 hours, Barca will now step up their search to find experienced cover for the left-back.
Mundo Deportivo says Barca are shopping in the Bosman market, with Monreal a priority.
Alberto Moreno (Liverpool) and Filipe Luis (Atlético Madrid) are others under consideration.
Barca also have plans to allow Juan Miranda to move on in order to make room for a planned veteran fullback addition.
