Saudi Arabia - Japan 
The last match of the second group and Japan having secured first place (2-0-0) already knows its opponent in the next phase that is Iran (2ο in the Club). He avoided the Qatar hosts but fell on the other beast, so he would well avoid being punished, injured, and wasting forces in a totally irrelevant game.
The two-point Saudi Arabia (0-2-0) is definitely a win, since behind it with one grade (0-1-1) are North Korea and Thailand playing with each other. He can also go through a draw but this will only be the case if the other two have a draw (scratch is?), And possibly be defeated if they lose only one goal and the others score a tie with a low score counts the goal difference and then the best attack).
Of course, the Japanese can not "catch up" and lose themselves voluntarily, but when the others begin to pick up and the strong markings what they will do? Her heroes? And with an emir referee who can make a little screwed eyes? That is, when the North Korean team (very good team) wins the other match, the organizers may say: "everyone is good for us"
