The changes made by several teams in the Saudi Arabian League have made the Saudi Arabian League increasingly attract more viewers throughout the world. Well, where I live, the Saudi Arabian League is becoming increasingly popular because of none other than the big influence of Ronaldo who joined Al Nassr. So it's not surprising that Ronaldo big name is what made the popularity of the Saudi League soar as the league is the most influential at the Asian level.
Saudi Professional League becomes more famous when Cristiano Ronaldo joined them and some other star players from Europe participated in like Benzema, Neymar, Mane, Brozovic ... This league gets more traffic rate from European football fans as some of them will watch matches in Saudi Professional League. It's their league growth globally but in their nation, the growth is not too much. There are many matches with so little audiences on stadiums and it's not good for their league attraction. Playing in many stadiums in Saudi Arabia is like playing matches during pandemic and serious quarantine.
However, if Ronaldo no longer plays in the Saudi Arabian league, I think the popularity of the Saudi Arabian league will decrease and that must be considered as best as possible by the management of the Saudi Arabian league. They must be able to maintain the Saudi Rana League which is the best compared to other Asian leagues. If you look at Ronaldo who continues to contribute to Al Nassr, of course the fans hope that Ronaldo will stay with Al Nassr for a long time.
He shown some signals that he will become their league brand ambassador and can be an owner of a club there or spent money to buy shares of a big club there.
Effects from Cristiano Ronaldo on Saudi Professional League are already seen but probably will become bigger and more meaningful in coming years like Zico's effects on Japanese League.
