What is the scenario for Vietnam to enter the quarterfinals of U20 Asia?

According to the tournament rules, when there is more than one team with equal points in the group stage, the head-to-head stats between the teams will be considered first to determine the ranking. Assuming Australia wins the last round, and Vietnam loses to Iran 2-3, these three teams will also get six points, must consider the confrontation criteria. At that time, the three teams were equal in the first two criteria, with three points and a difference of 0. respectively, but Iran will top the table by scoring more goals (5 goals), compared to Vietnam and Australia (both together). 3 tables). Vietnam and Australia will have to compare to the fourth criterion, and Hoang Anh Tuan's teachers and students are on top because they won against Australia.

But in the case of losing to Iran 0-1, or 1-2, Vietnam will be eliminated by scoring fewer goals when facing Iran and Australia. If they lose by two or more goals, Vietnam will be eliminated because the goal difference is lower than the two teams mentioned above.

Vietnam is leading Group B with two wins, 1-0 against Australia and 2-1 against Qatar. All four teams in the group still have the opportunity to progress and the risk of being eliminated. However, only Vietnam and Iran have the right to self-determination.

The bottom team of Qatar still has a chance to enter the quarter-finals of the U20 Asia if they win Australia by two goals or more, while Vietnam defeats Iran with any score.

If Vietnam wins in the quarterfinals, Vietnam will win a place in the U20 World Cup for the second time in history, after 2017.
