Even if you look at Al Nasr's current performance, I personally feel a little doubtful that Al Nasr can finish in 3rd place in the Saudi Arabian League. Because we can see for ourselves that this season there is Al Qadisiyah which will be the biggest obstacle for Al Nasr to finish in 3rd place in the Saudi Arabian League. Because currently Al Nasr is in 4th position in the Saudi Arabian league and has a difference of 3 points with Al Qadisiyah which is in 3rd place. With this, I personally can conclude that currently Al Nasr is unable to compete with Al Qadisiyah. So if Al Nasr cannot recover from its downturn, I think Al Nasr will most likely not be able to finish in 3rd place in the Saudi Arabian league. Maybe realistically Al Nasr can only finish in 4th position (if you look at its current performance).
Then talking about other competitions, this season Al Nasr is taking part in two competitions (apart from the SPL). Namely in the Saudi Arabian King's Cup and also in the Asian Champions League. In the Saudi Arabian King's Cup, Al Nasr lost in the round of 16 to Al Taawon. Therefore, currently Al Nasr only participates in the Champions League (apart from the SPL). I personally can't conclude whether Al Nasr will be like in the Champions League, but for now Al Nasr is in group B and is in 3rd place. Maybe with this, Al Nasr has a very big chance of qualifying for the next round.
That would be way too bad though, I mean I get that they can fail to win this season that makes sense and that's understandable but not being even third is too much. Second place was something they fought for last season, and this season the worst that could be accepted is third place because Al Ittihad is having a great season compared to last season but that's about it. If they finish anything worse than third place, that is a terrible season and shouldn't really be considered ok at all, something has to change.
I also believe that Ronaldo still didn't sign a contract extension so far, I do not have a clue if that's because the team hasn't offered anything yet, or if Ronaldo hasn't accepted yet or whatever is going on, but it's clear that we are seeing no extension yet. I doubt that he will get another 2 years 200+ million type of offer, that was good when he got here first, but now after this many years and no success, I do not think they will offer him that much money. If the season ends, and the offer isn't good and the team isn't even in the top three, I am pretty sure that Ronaldo will look for something else, that feels like the most important figure right now and could happen.
