Sosa has been told he can leave Bayern this summer.
"I am in Munich now awaiting interesting developments for Jose," agent Fabio Bilardo told Tuttonapoli.net.
"It's true, we did meet with director Bigon and had long discussions. The player wants the move and there's everything to suggest it should go through. He wants to amaze the fans.
"I would like to underline that there is also strong interest from Getafe, who are sending their emissaries to Germany on Monday.
"I think there is a bit of a gap between the demand and offer with Napoli, but that there is only a small difference and there is the very serious intention of giving the player to Coach Walter Mazzarri."
