There is no doubt that Al hilal has a good chance of winning this match. Al najma is not a team that is on par with Al hilal in terms of strength. previously, Al Nassr and Al Ahli also defeated Al-Najma by a large margin. so I think Al-Hilal will do the same in today's match. at least 3 goals will likely be scored in this match.
The match between Al-Ahli and Al-Ittihad will still be a difficult one to predict. although I believe Al-Ahli is in better shape at the moment, Al-Ittihad cannot be underestimated. therefore, I might prefer not to favor either team in this match.
No doubt, Al Hilal will easy get three points against the most bottom team Al Najma have loss 5 of last 6 matches in domestic league, Al Hilal want to pressure Al Nassr at top standings and won't loss three points make difficult get chance keep in the tittle race with Al Nassr and Al Ahli.
The match Al Ahli vs Al Ittihad seems difficult for predicting indeed looking last several matches of Al Ahli performing well but Al Ittihad ever holding draw Al Hilal last several weeks ago. Al Ahli if can secure three points by defeating Al Ittihad has chance for awhile back to top position behind Al Nassr will play this week match on Sunday night against Neom.
Of the three matches you mentioned, only Al Hilal and Al Nassr can claim three points, while Al Ahli will struggle to steal points against Al Ittihad, the defending champions from last season. Even Al Hilal struggled to beat Al Ittihad, even though they were reduced to 10 men due to a red card.
So, I can say that in Week 25, Al Nassr remains at the top of the standings. With their improving performance, they are predicted to be able to defeat Neom SC, especially since this match is at home. Al Hilal is followed in second place, as they are not expected to struggle to win this match, as they are against a team at the bottom of the standings. Al Najma has only managed eight points in 24 matches. Al Ahli will drop to third place, as facing Al Ittihad is not easy, and a draw is likely.
