Honestly, I'd rather sell Neymar than pay him huge wages for that so years. 222-250 million would be a good price.
PSG cannot afford that, and there's little point in Barca agreeing a deal and getting that paid in installments. If they pay out the clause, they take that much money out of the club at once which is impossible even for them. With that much money, it'll be difficult for us to sign replacements too as every club would demand a lot.
If PSG ever want Neymar, we should demand Verratti + cash in return. It's the best deal for both.
First secure replacements, then pull the trigger.
