Real Sociedad will reportedly target Espanyol goalkeeper Kiko Casilla if current first-choice stopper Claudio Bravo joins Barcelona this summer.
Bravo, who is currently on international duty with Chile, is widely expected to complete a move to the Camp Nou before the start of pre-season training next month.
According to Inside Spanish Football, Sociedad want Casilla as Bravo's replacement, with the 27-year-old also expected to seek pastures new this summer.
Casilla, who has also previously been linked with a return to former club Real Madrid, has just one year remaining on his current Espanyol deal.
