Al-Hilal have increased their offer in a desperate attempt to sign Napolis Victor Osimhen this summer.
The figures could make Osimhen the highest-earning footballer from Africa.
According to Goal, the Saudi Pro League side have tabled a contract offer worth up to 50m per year without bonuses, in a bid to tempt the 26-year-old.
Al-Hilal already offered to pay Osimhen 30m per year, after they activated his 75m release clause, but he rejected the offer.
Despite hoping to wrap up the transfer before the Club World Cup, Al-Hilal failed to strike a deal.
