Sala has been continually linked with a move to the Stadio Giuseppe Meazza this summer, as well as a number of other Serie A clubs including Napoli.
According to Sport Mediaset, the Biscione sent a scout to survey the Italian one last time.
It is thought, however, that the former Chelsea man is only an alternative option should Inter miss out on their other targets.
Sala joined the Mastini from Bundesliga side Hamburg in 2013 and since then has made 31 appearances for the Gialloblu.
The 23-year-old from Bergamo is also a versatile player and can be used at right-back.
