Correct, but it is a two-way benefit. No doubt, Cristiano Ronaldo accepted the offer to play for the Saudi Arabian league for money. If they had offered him anything less, he wouldn't even think of playing there. However, it is also that the Saudi Premier League needs him to play for their league. This will give a lot more popularity to this league when you know the big names are playing there. Anyway, all this is possible because the Saudis have a lot of money to bring football home. They are also the hosts for the 2034 FIFA World Cup. 
Well that's right. Because Cristiano Ronaldo came to a club in the SPL, namely Al-Nassr, also because of the high offer he received to play for this team. And that is very profitable for Cristiano Ronaldo, who is no longer young but still gets very high offers that even beat young players who are currently popular. And Al-Nassr, other clubs and the SPL also benefited from Cristiano Ronaldo's arrival there. Because we also immediately saw an influx of other star players from Europe to other clubs in the SPL. For example, Al-hilal, Al-ittihad and many others also immediately got many other European players who followed in Cristiano Ronaldo's footsteps. And yes the popularity of SPL is also increasing rapidly. But I'm curious what would happen if Cristiano Ronaldo left the SPL again?
