Talking about Ronaldo reaching one thousand goals, I think he will definitely achieve that in two seasons to come, that's this season we're about to enter now and next season. As you said that he already has 938 goals which is true, he needs another 62 goals to get to 1,000 goals. He needs to average 31 goals each in these two seasons for both clubs and country across all competitions to achieve this of which is very visible and achievable for him.
Two seasons is certainly the ideal time for Ronaldo to reach his 1000 goal target. Because as we know, Ronaldo currently needs 62 more goals to make it 1000 goals, and in 2 seasons of course it is likely that Ronaldo can easily achieve it. Because as far as I know for more than 2 seasons with Al Nasr, Ronaldo has been able to score 99 goals from 111 appearances. So with this evidence, I personally am really sure that in 2 seasons Ronaldo will definitely be able to break his 1000 goal record. Even if Ronaldo can be more productive in scoring goals, I think in 1 to 1.5 seasons Ronaldo could break his record.
But the problem is whether Ronaldo has been given a contract extension or not. Because if Ronaldo doesn't play at Al Nasr anymore, I think it will be quite difficult for Ronaldo to break his record. Because at Al Nasr Ronaldo already has good chemistry with his teammates, so of course it will make it easier for Ronaldo to score a lot of goals. So I hope Ronaldo gets another contract extension at Al Nasr. But until now there is no clarity regarding this, even though it is now June 22, which means Ronaldo's contract will end soon. So with this, Al Nasr needs to move quickly now.
