The 22-year-old Italian has established himself as Alan Pardew's first-choice left-back but could find himself pressed into service on the right instead when Norwich head for St James' Park on November 23.
France international Mathieu Debuchy is suspended after collecting his fifth booking of the campaign in Sunday's 1-0 Premier League win at Tottenham, and with no other specialist right-back in the senior squad, Santon could be the man to plug the gap.
He told the Shields Gazette: "I can play right-back. I prefer left-back, but I know I have to improve my left foot.
"When I play left-back, I can go left to right. When I play right-back and try to go inside it is a little bit more difficult, but I enjoy both.
"If the manager needs me to play right-back, I am here to play where he wants me."
However, Pardew's decision may be dictated by a series of injury concerns.
Massadio Haidara and Paul Dummett, natural replacements on the left if Santon was to move, are both battling to shake off hamstring injuries.
But skipper Fabricio Coloccini returned to the squad after a groin problem at the weekend and his availability could tempt Pardew to ask Mapou Yanga-Mbiwa, who has partnered Mike Williamson in the middle in recent weeks, to line up at full-back.
