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.
