Arturo Lupoli is almost certain to leave Fiorentina in the January transfer window, according to the player's agent.
The Italian striker joined Fiorentina from Derby in the summer but has become frustrated with his lack of opportunities.
Agent Claudio Pasqualin revealed earlier this week that Lupoli could be headed back to Derby in the New Year.
However, Napoli are also believed to be interested in Lupoli and Pasqualin admits his client's future is still uncertain.
"This summer he chose Florence, which turned out to be a mistake because he doesn't play," Pasqualin told the Italian press. "It's clear he will leave.
"Napoli? There are no developments, despite the fact that chief officer Pierpaolo Marino has always shown a lot of admiration in Lupoli."
