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.
Ronaldo, the G.O.A.T and his unwavering display of goal scoring abilities, skillfulness, agility and strength which generally goes contrary to every activity his age can be able to carry out. Age is not a hindrance to him, he works hard to keep himself active and truthfully, there's every possibility that he'd take part in the next world cup cos he's just got all it'd take.
He'd definitely look far younger than his age by then as well.
So in essence, age won't deprive him as long as he wants it to happen, he can work towards it, it's just for him to keep his body shape, he's just got all it takes so the task won't be so bulky on him. The world cup is just in 3years, that's not so much time to say that he'd loose his shape and form of professional football. He makes football seem like his hobby cos he strives to keep on going with it. Yes a day for his retirement would come but it's very highly possible that 2026 world cup would go on with Ronaldo and his Portuguese internationals with him.
