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.
Outstanding players doesn't anticipate in the competitive title race for their perspective clubs. Saudi Arabia are in possession of elite players, that's totally concord. The top firms generates resources to fund the expenses of these elite teams. They go for players that will serve routes to popularity for the club. Saudi Arabia focused on bringing in European players, these are players that are focused on winning games. Cristiano Ronaldo is one of the major influence to SPL. Since his presence in the league, it brought SPL to limelight, now everyone craves to watch the epic performance of these teams. Ronald is big name in football, who doesn't know the Portuguese? He created impact and record in Europe before making the moves to join an SPL elite side. He's comfortable since accomplishing memorable titles and working on doing the same in Saudi Arabia.
