Juventus could propose Daniele Rugani to Milan in exchange for Mattia De Sciglio.
According to Mediaset Premium, little-used centre-back Rugani is being offered in a straight swap with the versatile full-back.
Max Allegri launched De Sciglio into the senior squad and has repeatedly been linked with a reunion in Turin.
Now that he has rediscovered his confidence with Italy at Euro 2016, his value has shot back up.
There have even been links with Barcelona for the 23-year-old.
It would be a surprise move, as Juventus rejected big offers from Napoli for Rugani.
Milan already have Alessio Romagnoli, so would recreate the current Italy Under-21 international partnership.
