Fiorentina are in negotiations with Palermo for an end-of-season deal for defender Andrea Barzagli.
Corriere dello Sport says part of Federico Balzaretti's move to Palermo included Fiorentina securing first option on the Rosanero captain.
Fiorentina are now negotiating a fee with Palermo for Barzagli, which would come as a huge blow to Juventus and Lazio.
