if he really want to come and psg ask 300m.. he could put 200m and barca 100m. he pay for his release clause also when he goes to psg if i remember.
that was the qatar state who gave money to neymar(through a sponsorship contract for the 2022 WC) so that he paid the release clause.
our ties are with japan now(rakuten, konami, canon medical). so, don't see how we can pull off a deal like that.
if neymar had cristiano ronaldo's level of dedication, professionalism and fitness i wouldn't have a problem paying 300mil. but right now we are looking at the average brazilian superstar attacker, who just wants to party himself in to an early retirement.
