The 21-year-old enjoyed a good first season in the Premier League after joining from Inter, making 27 appearances as the Magpies defied expectations and only narrowly missed out on the Champions League.
Santon has been linked to a move back to Italy with Roma being touted as a potential destination, but the Italian full-back says he has only just arrived in England and feels it is too soon to pack up and leave.
He told calciomercato.com: "I know Roma are looking for a right-back and they showed interest in me some time ago, but Newcastle immediately refused to give me up.
"That's okay for me because I have familiarised myself in England and I have no plans to move. I've only been here for a year and it is too early to pack up and come back to Italy."Meanwhile, Newcastle themselves have been linked with Lille and France right-back Mathieu Debuchy.
However Santon, who can play on either side, says he doesn't feel threatened by Debuchy's potential arrival.
"Debuchy to Newcastle? I am calm," Santon said.
"Pardew had told me that he had thought about playing me on the right, but also that another right-back would come.
"Debuchy or whoever, is welcome, especially if it is a good player who can help the team. Then, we'll see who the coach decides to pick."
