Ronaldo has good support from his team mates and he receives many key passes as well as chances to take penalty shots for Al Nassr. If he won't get injuries, he will be able to score more goals for Al Nassr and can aim at his 1000th goal.
That goal target is achievable if he won't get serious injuries in next few seasons. Because he does not show he wants to retire before his body no longer allows him to play. And we know, if he plays, he can score goals as he has shown through his long career.
I think Ronaldo will still have a long way to go if he gets injured because we also know that he always looks after his body. While his teammates are on holiday, he spends more time training his muscles at home and we can often see the results with the consistency he displays. I don't think there is a player who is as consistent as Ronaldo in maintaining his fitness and even though he is no longer young and almost 40 years old, everything is still impressive.
The target of 1000 goals is a record he wants to break before retiring and maybe we will see him in two more seasons if he is able to score the same as the end of 2023 with more than 50 goals. That is, if he still survives to play football with the club and the Portuguese national team amidst competition with other young players.
