Only the winners of the six groups are guaranteed a place at the Asian Cup along with the five best runners-up, meaning only one second-placed team will miss out.
And after Palestine secured their place at the tournament as Group B winners with a 4-0 victory over Philippines in Tuesday's early kickoff, it means that any team with a six-point haul already to their names will be marching on even as one of the best-placed runners-up.
This is due to the fact that the second-placed team in Group B -- whether it be Philippines or Yemen -- will now only achieve a maximum of four points.
Having made history at the last Asian Cup by making their tournament debut, Philippines will now face a nervy wait to see if they will be qualifying once again from what has been a disappointing campaign.
Although it was hardly the easiest group they could have found themselves in, the Azkals will feel they could have taken maximum points in their opening 0-0 draw with Yemen, while they were also fortunate to beat minnows Mongolia 1-0 courtesy of a 93rd-minute winner from debutant Gerrit Holtmann on Saturday.
The other two teams presently occupying the runners-up spots in their respective groups are Indonesia and Malaysia, with both having what look to be very winnable ties against Nepal and Bangladesh respectively later on Tuesday evening.
