Fiorentina face difficulties for Juventus midfielder
They, along with Everton, have known to be casting their eye on the Azzurrini international but it will not be easy for them to try and sign him.
According to Sky Sports, Vincenzo Montella views the 23-year-old as the ideal deputy to David Pizarro but the Viola only want to sign the player on loan for the coming campaign.
However, the Bianconeri are not willing to part with him on loan and are requesting €10 million for Marrone and refusing to send him out on loan.
This has made the transfer of the player very unlikely and it would therefore be very surprising if he does make the switch to Florence.
