Lazio have stepped up talks with Panathinaikos for striker Djibril Cisse.
It is believed they have offered 5m for the player, although Panathinaikos are hoping for 6m.
"At this moment the economic situation is not the best, so to keep going we need to sell some of our important players and replace them with promising youngsters," Vice-President Dimitris Gontikas told Cittaceleste.
"We are in negotiations with Lazio, but at this moment in time we have no intention of revealing further details."
