Palermo have confirmed that they have already reached an agreement to sell Mattia Cassani to Fiorentina on a permanent basis.
The Italian international joined the Viola in the summer on loan until June 2012, but it seems his long-term future will be in Florence.
"We have already reached an agreement with Fiorentina," Palermo sporting director Sean Sogliano told Firenze Viola.
"There will not be any problems with regard to Fiorentina taking up their option to sign him outright.
"Could a deal be brought forward and completed in January? That's irrelevant. Cassani is already a Viola player."
The former Juventus youngster will cost Fiorentina €4.5m – a fee that was pre-agreed between the two clubs during the summer.
