One team that has fallen behind this season is Al-Ahli. Similar to the case with the three teams mentioned, they are also funded by the Saudi Arabian Public Investment Fund. And they have some big names in their squad (Roger Ibañez, Roberto Firmino, Édouard Mendy, Franck Kessié.etc). At the moment, they are trailing at the 8th position in points table, with teams like Al-Taawoun and Al-Qadsiah ahead of them. Anyway, the season just got started. We still have plenty of matches remaining.
You're right. Al Ahli performance is decreasing very badly, they are only in 8th place now. It was very different in the last season, at that time they were in the top 3. Although this team has some big players, they have no enough good players in midfield line. Franck Kessié alone can't make their midfield line to be strong enough. I think improving the quality of midfield line is the key to improve the performance of Al Ahli team. Although there are many matches left, it is important to improve their performance as quick as possible.
