Fiorentina and Catania are still discussing terms over the proposed move of Maxi Lopez.
The Viola are expected to make a bid for the Argentine given the likely departure of Alberto Gilardino.
Catania are prepared to sell the former Barcelona hitman, but a compromise over a fee has yet to be reached.
The Tuscan giants, who should net in excess of €11m for Gilardino, have so far offered €8m for the South American.
Catania, meanwhile, are asking for €10m.
