The 22-year-old joined the Partenopei from Hellas Verona last weekend, and he says that he wants to give his all for his new team.
"I just want to give my best in this shirt," Jorginho told reporters. "My goal here is to learn from my new teammates and from the coach.
"I am here to give my best for the club. I can play in many different positions, but I think I do my best work when I'm in central midfield.
"I don't have any real goals from the season. I just want to go game by game and see what happens. I can look back at the end of the season and see whether it's been a successful one or not."
Jorginho has scored seven goals in the league this season for Verona.
