At this time I cannot agree to saying the Saudi Arabia pro league is a top league already, they had a very good representation from Al-Hilal and that is an obvious fact as seen in the tournament but they had a few of other representations that crashed out so soon, so it is even better to see that as an individual team effort that felt like a representation of the league, they still have a lot to do to fix the league and buying of quality players is one of it and until then, I still regard them as an average league but with progressive improvement actually.
Indeed. Saudi Pro League isn't in the level of top leagues in the world. However, it becomes more popular now. We must admit that almost everyone in the world probably knows Saudi Pro League due to Ronaldo's factor. Regarding the achievement of Al Hilal defeated Man City and reached the quarter-final, it is not enough to prove the quality of Saudi Pro League. However, we can't deny that some big teams in SPL are strong enough because they can show quite good performance in international competitions (FIFA club world cup, AFC champions league). Sure, there are many things that should be fixed in SPL, including the players' quality and the equality of squad strength between teams. But it seems having quite good progress recently.
I am telling my story that I have known about the Saudi League since Cristiano Ronaldo joined a club in the Saudi League. Cristiano Ronaldo has been playing in the Saudi League for maybe two to three years now and I have been following the Saudi League and trying to watch the games of the Saudi League. Maybe there are many more football lovers like me who follow Ronaldo and watch the games of different clubs in the Saudi League. However, in these few years, different clubs in the Saudi League have made a lot of progress, especially Al Hilal, which must be praised. Al Hilal qualified for the Club World Cup, where they defeated Manchester City by a large margin in the second round after passing the first round. Al Hilal's defeat of Manchester City created a lot of excitement in the football world and many people thought that in a few years, Al Hilal might qualify for the Champions League from the Saudi League. Since the different clubs in the Saudi League have enough money, they will definitely take their league to a better level.
