Tuttosport understands that Juve are ready to swoop for Astori if Leonardo Bonucci is suspended for his part in the match-fixing scandal currently sweeping through Italian football.
Bonucci has been charged along with Juve teammate Simone Pepe and could face a ban of three years if found guilty of match-fixing offences.
The 25-year-old Astori plays predominantly as a centre-back and could join Juventus as cover later this summer.
Astori spent a number of years in the youth system at AC Milan but never made a first-team appearance for the Serie A giants.
Juventus have been left in limbo in the wake of yet another match-fixing trial in Italian football, with manager Antonio Conte also under investigation.
