Dybala doesn't have the star and marketing power of Neymar. Can't see PSG in a million years let Neymar leave so soon.
Probably not, no. But if rumours are true and Neymar really is unhappy, Dybala would allow PSG to save a little face at least. But no, I agree, I'd be very surprised if they let Neymar leave. I suppose it depends on how unhappy he actually is, and how vindictive they are. I mean, if ever he did start agitating for a move, financially they could of course leave him to rot in reserves. But that wouldn't be great for their reputation either, and in fact could work against them because it would put potential signings off. Personally I think if he wants out ever, and is really prepared to force it, he'll get his way. After all, at this point PSG have the money of a top club but not the prestige, or the credibility that on-field success brings, and it would be counter productive for them to try and "enslave" a player like Neymar. Verratti's one thing, but imagine the fuss Neymar would make? They'd try and spin their keeping him as a sign of strength of course, but the fact remains, if your poster boy no longer wants to play for you (This is all hypothetical, just to clarify; I have no idea if Neymar is unhappy or not), keeping him as punishment just makes you look a bit pathetic. Imo.
