Currently, SPL has become one of the elite leagues in the world because Saudi Arabia has brought in many world football legends, even some of them are great players from Europe who are in their prime such as Neymar, Benzema, Mane, Kante and many more. This is expected to be a competition that will make Saudi Arabian football better. But on the other hand, currently the fact is that most of the Saudi Arabian national team players are only filled by bench players from their clubs because they are unable to compete with top players from Europe. Of course this is not a good thing for their national team. But on the other hand, I think in the next ten or twenty years, Saudi Arabia has the potential to become one of the strongest football countries in the world. That can happen if they are consistent because I am sure that in the future there will be many young Saudis who will be interested in football.
You have a point, Saudi Arabia has a promising future with the rise, development through investments and improvements in its football infrastructure. There is no point in nations competing in every World Cup if they don't develop their football, this takes decades. There is a whole process of cultural adaptation, children need to grow up playing football as happens in brazil, which was once known as the country of football, exporting legends.
Saudi Arab new generation rulers are doing right decisions for their future because due to having two holy cities every year we have millions peoples visiting this country so now they are bringing few changes which will increase tourists in other cities because their investment in soccer, tennis and few other sports surely attract peoples and things will take good changes now their successful bit of FIFA World Cup 2034 is having huge positive impact on their reforms.
World taking changes and many countries have good chance of jumping from their old heritage to have modernization with the AI we will be able to have things beyond our mind approach Saudi Arab and Gulf region countries can do right things with their huge funds which will help them for staying ahead of countries those will join things like these in near future.
