All we know is that Dybala's #1 priority is staying at Juve, and is that really a bad thing? It shows he has loyalty and character, willing to fight for his place even though he's disrespectfully discarded by the club. We also know that he'd prefer Barca, RM and PSG as his next destinations, but that's not happening for him. There's only one source claiming he doesn't want United, and it's a dubious source to say the least.
So yeah, we're his fourth choice at best - then again, can you blame him?
