If he doesn't get a suitable offer to play in Europe then Ronaldo will definitely stay at Al Nassr because as you said and the way Al Nassr treats Ronaldo is very special because he feels at home with the environment he wants. Ronaldo's presence at Al Nassr has a big impact and it's not only for the club but also for the Saudi Arabian League itself because we know that in the past the league was not talked about by the world at all.
It's better to chase the target of 1000 goals for Ronaldo than trying to maneuver in Europe because I'm sure no club wants to pay his high salary there. The same goes for Alejandro Garnacho because he should have stayed in Europe rather than moving to the Saudi Arabian League so quickly.
Al-Nassr really provides many special things for Cristiano Ronaldo. So Cristiano Ronaldo himself felt very at home there. Apart from the large salary, we know that Cristiano Ronaldo's family also seems to really enjoy their life there. So the sense of comfort they have received will really make Cristiano Ronaldo stay at Al-nassr. In fact, I too, in the Al-Nassr way, really respect Cristiano Ronaldo. And yes, all SPL viewers, the Al-Nassr club, and also for the SPL itself, the figure of Cristiano Ronaldo now seems inseparable. He seems to have become an important icon that must continue to be maintained. Because the SPL became better known because Cristiano Ronaldo accepted Al-nassr's offer and played at Al-nassr.
And I think it would be better for Cristiano Ronaldo to stay focused on the target of 1000 goals that he wants to achieve.
