Jorginho is counting on Davide Zappacosta to help him settle quickly at Chelsea.
The midfielder joined Chelsea last week from Napoli.
He told chelseafc.com: "I know Davide Zappacosta from the Italy team. I also know a few others who I played against like Marcos Alonso, Emerson and Alvaro Morata. I have not had the chance to get to know them as people but I have come across them on the pitch. It is really helpful to have someone here I know like Davide to help me settle in, particularly when I am in another country that I don't know yet.
"Today everyone watches the Premier League so I have watched plenty of it times in my time. It is a fantastic league, the best in the world I think."
