PSG was out of the picture the second Juventus made a bid for him. The main reason was the release clause Raiola was adamant to put in his contract, clause that is forbidden in french football contracts.PSG (not even the rags would pay him what his agent would demand).
There is literally nowhere else he could go without Juve writing off a big chunk of money and the lad taking a big pay cut. So yes, I suppose Juve will have to give him time.
However, it might just be the elegant excuse given to PSG because de Ligt prefers Juventus. PSG went on buying Diallo instead for a significantly lower fee and salary but got a significantly less promising player.
Buying de Ligt, a 19 y.o player, is an investment for the future. Juventus will stick to their guns.
Even Rabiot who is a benchwarmer isn't being sold or vloaned out despite interest from PL clubs.
