Domenico Criscito's agent denied the Napoli move collapsed due to money, but reports now push him from Zenit to Gian Piero Gasperini's Inter.
Genoa had agreed a fee with Napoli, but the failure to find a deal on personal terms saw the defender back on the market.
“A professional evaluates every aspect of a club before making a move,” agent Claudio Pasqualin told Radio Kiss Kiss.
“That includes the economic aspect, but also the environment you are going into. The career of a player is brief and he has to make the most of his opportunities while he can. Once he has evaluated everything, he will make his decision.”
There were strong reports of a deal in place with Luciano Spalletti's Russian club, Zenit St Petersburg.
“Yes, we are evaluating the Zenit option, but also others,” added agent Andrea D'Amico.
“There was no bidding war with Napoli, as there was simply a difference of opinion on the project.”
However, new media sources suggest Criscito could remain in Serie A after all with Inter.
He would reunite with his former Genoa Coach, Gasperini, and avoid a big move to another country when his partner is expecting.
According to the Gazzetta dello Sport, Zenit are offering a five-year contract worth €3.5m per season.
Inter could meet the €12m asking price, but the wages are a different matter.
