If Milan fail to sign Mateo Musacchio from Villarreal, they could ask Juventus for Daniele Rugani on loan with option to buy.
According to Sportitalia, the Rossoneri are keeping an eye on Rugani as an alternative to first choice Musacchio.
Juve have repeatedly turned down offers for Rugani from Arsenal and Napoli, among others.
The centre-back already had very little playing time last summer and the arrival of Medhi Benatia from Bayern Munich will limit his possibilities even more.
Rugani would cost at least €30m, but Benatia’s presence means Juventus could in theory loan him out to Milan for one season.
It would reunite him with Alessio Romagnoli, his teammate in the Italy Under-21 defence.
