Fiorentina president Rocco Commisso can't rule out selling Dusan Vlahovic this month.
Atletico Madrid and Tottenham have been in contact for the Serb this week.
“At the moment it's really a difficult thing to discuss, because even I as President of Fiorentina do not have any certainties about this," said Commisso to news agency ANSA.
“If something happens, then the media will be informed with transparency and in good time.
"The intention, nonetheless, is to continue keeping him."
He added: "If we're talking about €100m, then I'd think about it carefully. The pandemic caused notable damage to all clubs, including Fiorentina.
"You cannot turn your back on certain sums of money just to be arrogant."
