The bottom line is, money talks. There's only one reason why Neymar is leaving Barcelona for PSG. Cash. Really, I can't even blame him. PSG are offering him an insane contract. All the talk about wanting to step out of Messi's shadow is complete nonsense. Had Barcelona offered him a huge raise, Neymar would have stayed. He's leaving for the money. Simple as that.
While most won't agree with the fee (it's a ludicrous investment for any player, let alone the FFP implications), it is a huge statement of intent from PSG. For all of Woodward's talk about United being able to compete financially for any player, there's no way the club would be prepared to pay that much money. If people think we blew Real Madrid out of the water last year with our Pogba bid, then PSG blew us, and everyone else, out of the water this summer.
