The 30-year-old defender is currently on loan at Stadio Olimpico having slipped down the pecking order at United.
Smalling has earned plenty of plaudits during his time in Italy and admits that he would be open to the idea of staying in Serie A.
He told BBC Sport: “Yeah, I think the plan at the start of the season was to contribute as much as I can and then hopefully if we’ve all had a good season and hit our ambitions then those discussions can take place.
“I’ve been more than happy with my first half of the season, it’s now just making sure that we kick on and finish the season strongly because we have a lot to play for.
“Coming over here and trying to hit ground running with football was the priority. But my family settling in and me learning the language and enjoying the culture, it’s something you need to make the most of.
“My family and I definitely are.”
His fine form has led to suggestions that he should be in contention for a place in England’s squad this summer.
Smalling has been overlooked by Gareth Southgate in recent times, but there remains a desire on his part to add to a collection of 31 caps.
“Obviously it’s been a couple of years now, but that ambition is always there with England,” he said of his international ambition.
“I know that Gareth and the coaching staff have been to a few of my games over here and I guess you know you are in their thoughts if you are playing at a top club.
“I hold those aspirations, and I just try to focus on here and what comes, comes. But I would very much like to be part of [the Euros], for sure.”
