2:58 Highlights from United's 2-1 Premier League home defeat by Crystal Palace last Saturday
The Serie A side have seen stalwart Kostas Manolas leave for Napoli for €36m this summer but need more cover after bringing in Italy U21 defender Gianluca Mancini from Atalanta for €20m.
Smalling is currently United’s longest-serving player following his £7m move from Fulham in 2010 and was a regular following Ole Gunnar Solskjaer’s interim appointment last December.
However, he has fallen down the pecking order at the club following the world-record move that brought Harry Maguire to Old Trafford.
European clubs will be able to sign players until Monday September 2, with Spain’s La Liga, Italy’s Serie A, Germany’s Bundesliga and France’s Ligue 1 closing their business at varying times in the day.
