The goalkeeper's representative confirmed he is set to leave Stadio San Paolo this summer but was coy on rumours linking Roma with a bid
The Partenopei have already bolstered their shot-stopping ranks with Rafael this summer and are believed to be close to a season-long loan deal for Liverpool and Spain keeper Pepe Reina.
The 36-year-old Italy international has been linked with a move to Roma ahead of the new Serie A season but Federico Pastorello only confirmed that his client's departure is extremely likely.
"Am I certain of Morgan’s move to Roma? There is nothing certain on the transfer market," De Sanctis' agent told CalcioNews24.
"I can only say that he will almost certainly leave Napoli."
De Sanctis joined the Serie A runners-up in July 2009 in a €1.7 million move from Sevilla.
