Fiorentina are preparing to sell Nikola Milenkovic this summer.
Viola captain German Pezzella could also be transfer-listed with the pair now inside the final year of their contracts.
Corriere dello Sport says Fiorentina don't want to see the players leave the Artemio Franchi for nothing, so they will listen to offers if new deals cannot be settled.
Club chiefs are already considering replacements with Marija Nastasic (Schalke 04), Andrea Cistana (Brescia) and Javi Sanchez (Valladolid) in their sights.
