In essence, Al Hilal managed to consistently get trophies without fancy players because after all, despite the fact that Al Hilal had Neymar but Neymar also only suffered injuries throughout the season. So, I think Al Hilal doesn't really need Ronaldo to get trophies, but Ronaldo himself needs trophies so is willing to join Al Hilal. Despite the fact, if for example Ronaldo plays for Al Hilal I believe there is no guarantee for Ronaldo to get a trophy there. So, if for example later Ronaldo plays for Al Hilal and then Al Hilal becomes a team that fails to win trophies, then it will be a bad judgment for Ronaldo himself, at least it will be a risk and or consequence if for example Ronaldo joins Al Hilal.
It seems that C. Ronaldo has to lower his ambition a little to be able to conquer RSL. Ronaldo has been at Al Nassr for almost 2 years, and one full season with Al Nassr is not enough for Ronaldo to bring his team to win the title. And if he moves to Al Hilal just to win the trophy, it will only further show Ronaldo's inability to bring his team to win the title. If he moves to Al Hilal, it is the same as Ronaldo only relying on Al Hilal to win the title. and that does not show the attitude that the mega star should show at all.
That's what I mean, it would be a shame if Ronaldo really moved to Al Hilal. As I said before, of course it would be very bad if, for example, Ronaldo really moved to Al Hilal but in reality Al Hilal would fail to win a trophy. If that happens, it will have a bad impact on Ronaldo's career and also his status as a world mega star player. Thus, it would be very good for Ronaldo to stay at Al Nassr, but if for example Ronaldo really wants to leave then joining another team other than Al Hilal would be better, or moving to a different country and league, to MLS maybe that would have a good impact on his career there too, who knows.
