The Italian Under-21 international is rated highly by the Turin outfit, but he has struggled for regular action over the last few seasons.
Marrone is a central midfielder, but he was transformed into a centre-back by Antonio Conte this term to act as cover for Leonardo Bonucci.
Conte is a fan of the 23-year-old, but Marrone was used in only 15 games this term. He featured in just six during 2011-12.
Marrone, represented by Beppe Bozzo, is understood to have admirers in the form of Parma, Fiorentina and Sampdoria.
