The Italy international moved to St James’ Park from Inter Milan in 2011 and has two years left on his current contract with the Premier League club.
The 23-year-old defender insists he is happy at Newcastle and has no plans to return to his homeland.
Santon told Sky Sports Italy: "There has been interest from AC Milan and AS Roma for me, but I have two more years on my contract with Newcastle and I don't know if they want to sell me.
“I'm fine at Newcastle, I immediately felt at home there and I like the Premier League.
“I think I won't return to Italy this summer."
