European club officials have traveled to Saudi Arabia in recent weeks to discuss possible summer deals with SPL sides, according to Marca.
Barcelona, Chelsea and Manchester United are interested in offloading several stars amid Saudi interest.
Barca are hoping to sell Robert Lewandowski and Raphinha in the next transfer window to recover some money for new deals.
Manchester United are also planning to do business with the Saudis and are ready to get rid of up to seven players including Casemiro.
The Saudi Pro League attracted a long list of high-profile stars in the last couple of years in accordance with the Kingdom's plan to diversify its economy.
