The 28-year-old has failed to impress at Anfield since joining the Reds from Udinese in the summer of 2008.
His agent, Roberto La Florio, has been working hard to secure a move away during the transfer window, but has dismissed rumours linking him with Russian side Zenit St Petersberg, instead focussing his efforts on a switch back to Serie A.
"I don't know anything about an interest from Zenit St Petersburg," he said. "But I can say that there was contact with Napoli and Roma also remain interested."
