Fiorentina sporting director Daniele Prade has confirmed offers have arrived for Dusan Vlahovic.
The Serb is a target for Arsenal, Juventus and Tottenham.
Prade told Sportitalia: “We received some important offers for him. Offers that were very substantial but we never got any feedback from his agents. On our side there has always been great transparency. I refer to what Barone said yesterday, all our doors are open.
“I say this because we want to understand what he wants and what the agents want. We're also open to sitting down again for the renewal. We have offers to sell him in a strong way. I'm saying this because a club that makes €75m a year and has a valuable asset cannot afford to lose him for free.
“We have to understand what he wants. We are open to everything. I don't leave room for other interpretations.
“We're open to everything. But the agents have to tell us their intentions.
“They were all valid and satisfactory offers, with payment methods that suited us. We couldn't go ahead with the deal because there was never any contact with the player's agents.
“It's an important valuation, over €70m. With no exchange deal and no way of paying in so many years. The president has imposed it on us."
