The Viola have declared he can be sold for €30 million.
"Do Juve have 30m for Jovetic? It's a big request," Marotta told Tuttomercatoweb.com.
"Everyone is free to determine the price they want. It's a legitimate right, but we have not entered into negotiations with Fiorentina. 30m is difficult and for now we will not talk about it.
"The fans like Robin Van Persie? You have to have dreams and ambitions, but then we must also deal with the reality of the facts. We know what we are doing and that is the most important thing."
