Fiorentina admit they're battling to tie down Adem Ljajic to new terms.
The midfielder has less than a year to run on his current deal.
"We need to talk to the player, who has already explained to us his desire to remain in Florence," said director of sport Daniele Pradè.
"Clearly conditions must be favourable for all concerned. There is time to discuss it and, if there are the right conditions, we'd be ready to renew his contract."
