Osasuna fullback Cesar Azpilicueta is a target for Barcelona.
AS says Barca sports chief Txiki Begiristain has already made an approach to Osasuna about opening talks for the Spain U21 international.
Osasuna turned down Begiristain's enquiry, but an auction for Azpilicueta is likely with Arsenal and Liverpool also keeping tabs on the fullback this season.
