I agree that nothing can compete with the European Leagues but the Saudi League is different from other leagues like China and America.
Saudi has a pretty good football federation so there is still a big possibility that the Saudi League will develop in the future.
Even though they are not yet able to compete and surpass the European Leagues, at least the Saudi League is increasingly known and liked by football fans.
The Asian and European castes are different in football and Europe has dominated football for a longer time, so it will be very difficult for the SPL to compete with them because this is a different regional zone.
The Saudi club have a lot of money and that's what makes their football so alive players will be attracted here because of the tempting offers, it won't be surprising to me that some other young players will be here in the future as the SPL competition is getting tougher in their league and also players are getting paid tall.
