Napoli have sold goalkeeper Mariano Andujar to Estudiantes.
Andujar spent last season on-loan with the Argentines.
He now has returned permanently, signing a three-year deal.
“This afternoon, Mariano Andujar signed a contract which ties him to the club for the next three years," Los Pincharratas confirmed in a statement on their official website.
“He will therefore continue to be an Estudiantes player."
