Santon has "no intention" of leaving the Premier League amid reported interest from Italy and Russia.
The Italian international has recently been linked with moves to AC Milan and Zenit St Petersburg after two years with the Magpies.
However, his agent Claudio Vigorelli said that the 22-year-old has put roots down in England and has no desire to leave.
"He has recently become a father, his girlfriend is English, and he has no intention to leave England or a championship as fascinating as the Premier League," he told IlVeromilanista.it.
Santon arrived at St James' Park from Inter Milan for £5.3m in 2011.
