Having played at the San Siro before, for fierce rivals Inter, the Italian would be happy to return with Milan as he has supported them since childhood.
However, the 22-year-old has declared that with his fiancee expecting their first baby, he is happy to be living in the North East and playing for the Magpies.
"I'm really happy in Newcastle. I like the city, the club and the atmosphere," Santon told Gazzetta dello Sport. "I'm also engaged to Chloe and we're expecting a baby in May. A return to Italy? At Newcastle I'm a king and I have a contract until 2016."
Santon admitted that it would be a difficult decision to turn down A.C. Milan.
"But I've heard of the interest from Milan in me and that is really pleasing because I have been a Milan fan since I was a child," Santon explained. "I'm not sure what would happen if another Italian club came in for me, but I'd seriously think about packing my bags for Milan."
Santon also admits reuniting with former teammate Mario Balotelli would be an extra incentive to join the Rossoneri.
"Balotelli? We were still friends and I'm glad he's doing well at Milan," Santon stated. "His presence would be an incentive to accept AC Milan."
