The defender is set to re-join the Nerazzurri on a Bosman free transfer once his contract at Chievo expires next month.
"He'll probably sign a four-year deal," agent Patrick Bastianelli told Sport Italia. "Is he liked by Mazzarri? Yes.
"If Napoli sporting director Riccardo Bigon made those moves then it is clear that he would have been wanted by Mazzarri.
"But that is water under the bridge. Andreolli is about to return to Inter and he is very happy about that."
