So the point is that the Saudi Arabian League must be able to produce new football stars, that way I am sure the Saudi Arabian League will attract more and more world attention.
Which player was born in Saudi Arabia and is famous and earns a lot of money like foreign players? The answer is simple: there isn't. So these native Saudi Arabian players are just watching the foreigners come to their country and take all the glory and are taking a lot of money and in 2 or 3 years they will leave for their countries and the native Saudi players will continue to play badly. When Ronaldo retires, this league will lose attention and many famous old players will not want to go and play in this league and the Arabs will not be offering these high amounts of money anymore because this is unsustainable in the long run.
So far, I don't see any really outstanding players owned by Saudi Arabia, and you are right they should look for potential young seeds who can compete and become stars. Ali Albulayhi, he is indeed known to many people, but we know that he is known as an arrogant player or one who provokes opponents in his own way. We can see some clips when he faced famous players. It is not impossible that they can have players who can make their name more famous, because after all a player who is famous for his abilities will make the name of his country more famous. Like one of the players in the Saudi Pro League for example, Ronaldo.
