it's clear that the quality of football does not match that of European leagues. Comparing leagues from vastly different regions and competitive levels can be challenging, as there are many factors to consider such as the level of competition, player development, financial resources, fan base, and historical performance in continental competitions. It's interesting that you've highlighted the performance of Al-Hilal and Al-Nassr, who appear to be the top teams in the Saudi Pro League. It's worth keeping an eye on the Asian Champions League to see if these teams or others from the Saudi Pro League can make a breakthrough in the future. While it seems the league is not yet on par with Europe's top leagues, it could still offer a unique and engaging football experience.
Indeed, comparing different leagues can prove to be a complex task. European football leagues often enjoy greater visibility and are generally considered more competitive due to various factors, such as economic resources, historical relevance, and player development and infrastructure. Nonetheless, this doesn't diminish the potential of other leagues such as the Saudi Pro League. As you've said, Al-Hilal and Al-Nassr have shown strong performances. The Asian Champions League could certainly serve as a thrilling platform for teams like these to shine and showcase their talent on an international stage. While it might not be on the same level as Europe's top leagues, the Saudi Pro League undoubtedly offers its own unique and enticing football experience.
