Osvaldo is being tipped to start in the game just a month after making his Azzurri debut against Northern Ireland.
"I hope to integrate myself well into a team that is doing really well," said the summer arrival from Espanyol.
"It's obvious that I want to have a great game that will be played in my home stadium, but Italy come first.
"I have made my decision to play for Italy.
"I'm Argentine, but I am also Italian. I see my future here in Italy."
