I agree with your opinion. In fact, since Al Nassr spent a huge amount of money to recruit Ronaldo, he has not really proved that Al Nassr spent that money is completely worth it, he only shined in a friendly match against Paris Saint-Germain, and official matches are lackluster.
I think Ronaldo is still a stranger to Al Nassr. Ronaldo tried very hard but he and his teammates still lacked coordination. Ronadol needs more time to practice with his teammates to combine better.
Ronaldo doesn't need more time, what he needs is more good players. We saw his performance at Manchester United and it showed that age has greatly reduced Ronaldo's performance. Al Nassr should sign more players that will serve Ronaldo with goal-scoring opportunities because he cannot create them. If the club thought that by signing Ronaldo they have solved all their problems, then they have made a terrible mistake. Ronaldo should be used for marketing and publicity, while the Al Nassr management put the necessary things such as quality players and coaches in place.
