Rumours have been circulating for a few hours now that Al-Ahli want to take Vinicius Jr. from Real, but Real Madrid are pointing to the transfer fee stipulated in the contract, which is 1 billion euros. I can't imagine that any club would pay that amount for any athlete, not even one from the Saudi league. Even for the clubs from Saudi Arabia, €1bn is a lot of money even if they had the money to pay.
It's impossible for that to happen...
Al-Ahli must already know that Vini Jr.'s release clause from Real Madrid is 1 billion euros (or more, who knows!? ) The Saudi club, rich as it is, would hardly reach that amount, which it would be the biggest transaction in football history. I believe that Al-Ahli will present a proposal of around 200 million euros in the next few days, if they can, but I see no reason for Real Madrid to accept this offer.
Would Saudi Arabia's Public Investment Fund (PIF), which is the country's main sovereign wealth fund, support Al-Ahli in this negotiation?
Many of the millionaire signings were only possible through the Ministry of Sports, which distributed the money to the clubs and made so many signings possible for astronomical values in recent years.... but honestly I doubt they will be able to get Vini Jr. either.
