Elia Caprile has left Napoli for Cagliari, with fellow keeper Simone Scuffet moving in the opposite direction.
The Sardinian team will have a right of redemption of around 8 million for the former Bari goalkeeper.
Scuffet joins Napoli as cover for Alex Meret, with Caprile moving to Sardinia in search of regular first team football.
Both deals are initial loan arrangements.
Scuffet moves to Napoli in a straight loan, while Caprile's arrangement includes a permanent option.
