Fiorentina paid 4.5m to buy half his contract a year ago, but the Friulani bought that back for only 110,000.
"Fiorentina offered 50,000 and we bid 110,000," explained President Franco Soldati on Radio Blu. "Therefore he is our player again.
"Now we will evaluate the situation along with Coach Francesco Guidolin and work out what is to be done.
"The same goes for Antonio Floro Flores. In the next few weeks, we will look carefully at all the players in the squad and decide what to do."
