The midfielder has struggled for action this season.
“Giaccherini is a product that isn't easy to find in January," Furio Valcareggi told TMW Radio.
“He's a player who is fresh and up to speed. We'll definitely leave Napoli and we're making moves.
“There's nothing from Russia or Turkey, that's just nonsense, but there's plenty of interest in Italy.
“I don't think Chievo will let [Roberto] Inglese [who is on loan from Napoli] leave in January now because the President is worried about their position, but we'd go there voluntarily.
“We like the team and the city, we'll wait and see. He's a player who can play anywhere as we saw at the European Championships.
“Fiorentina were looking at him over the summer, but I haven't heard from them now and that's a shame because he could make the leap at the Viola.
“I don't know about Atalanta, if they sell someone it could happen."
