Benfica are eyeing Barcelona's unsettled goalkeeper Jasper Cillessen.
Marca says the Dutchman is hoping to play regularly and he could find that at Benfica.
Portuguese press say that contact has already been made between the two parties, and Barcelona are ready to start negotiations.
Benfica unsuccessfully tried to sign him two years ago, and Porto are also interested, alongside several teams from Italy and England.
It will mean Barca needing to buy a new keeper this summer to act as cover for Mar-Andre ter Stegen.
