The Saudi Pro League wants to sign up to 50 players from Europe's 'big five' divisions this summer - including Lionel Messi.
Football is popular in Saudi Arabia, but the sport's infrastructure in the country is still growing. Saudi Arabia will host the Club World Cup in December, and they are in the running to co-host the men's international World Cup in 2030 with Egypt and Greece.
Attracting top players to the Saudi Pro League is a big part of the country's plan to establish themselves within the global game. Cristiano Ronaldo joined Al-Nassr in January - becoming the planet's best paid athlete - and more stars are expected to follow suit.
