Biagianti has been outstanding for the Sicilians this season.
Agent Roberto La Florio told TMW: “I am going to Catania. I will speak with the club and we will come to an agreement.
“Fiorentina haven't spoken to me directly, but I know that Marco is a player they like.
“But keep your eyes open because there is also interest in Marco from abroad, in particular from Spain.
“Catania will only sell him for an important offer, but if they were to decide to keep him that wouldn't be a problem.”
