Fiore has warned Lazio management not to sell the Serb on the cheap.
He told RMC Sport: "For the numbers that are now turning around football, he is worth the money because for quality and characteristics is a single player. I also watch a lot of foreign football but players like him are not there.
"An auction will open and we'll see what happens but if a defender in England is worth £70m (Virgil van Dijk) then Milinkovic-Savic is worth much more. That said, the market has gone crazy and should return to more normal figures."
