That proves that ronaldo's recruitment has been giving massive impact to the SPL. The popularity from the league is increasing with the goes of time.
I would not be surprised if people gonna consider SPL as one of biggest league in the future as long as there will always be money to be supplied to the SPL.
I think the clubs here in the Professional League cannot be compared financially with the clubs in the Chinese Super League because after all, the Saudi Professional League has Ronaldo while the Chinese Super League does not have a much number of star players like Al Nassr, Al Hilal and Al Ittihad. Thus, the two leagues have different efforts and thus, i'm quite sure that the Saudi Professional League will continue to grow. So, the capacity of the Saudi Professional League is certainly greater and I'm sure it will last a long time too, because they have money that is probably unlimited.
