Fiorentina president Rocco Commisso says Federico Chiesa could be sold this summer.
The attacker has been linked with a move to the likes of Inter Milan and Juventus.
Commisso said, "If Chiesa wants, then he can leave, but only for the figure that we set.
"It's a different matter for Gaetano Castrovilli, as he told me that he wants to remain in Florence.
"If Chiesa does go, then Castrovilli can have the Number 10 jersey."
