Sosa joined Napoli on a four-year deal from Bundesliga side Bayern Munich.
“Surrounding my client, there are many fascinating aspects that we will get to know soon enough,” Fabio Bilardo told Radio Kiss Kiss Napoli.
“He is a talented player, and I hope he has a great season.
“With Mazzarri, he has a good rapport, and he tells me that he is working well with him. Jose is at the full disposal of the coach and accepts any decision he makes.
“The German league did not suit the characteristics of my client, but the Italian one does. He also plays at Napoli, and for any Argentine, it is a dream to do so.”
