Adrien Rabiot has rejected PSG's attempts to open new contract talks.
With his deal now inside the final 12 months, the midfielder can sign a pre-contract with a foreign club from January 1.
AC Milan and Barcelona are in contact about ferrying Rabiot away from Paris next summer.
And RMC says they've now been joined by Juventus, which are also drawing up an offer for Rabiot to consider in the New Year.
Indeed, the French source says the Bianconeri are now favourites to sign the France international.
