The final round classifies the teams based on their FIFA rankings, putting Vietnam in the last tier with Lebanon. Teams in the same tier will not be in the same group, therefore, excluding Lebanon, Vietnam may clash with the other 10 teams that are Japan, Iran, Australia, South Korea, Saudi Arabia, UAE, Iraq, China, Oman and Syria.
The UAE are in tier three with Saudi Arabia and Vietnam have a 50 percent chance to be in the same group with one of them. If Vietnam are in the same group with the UAE, it would be easier for the Golden Dragons since Saudi Arabia are more experienced, having qualified for World Cup five times while the UAE qualified only once.
In tier four are China and Iraq. Although China are declining on form, they won all previous six encounters with Vietnam. For Iraq, Vietnam only drew one and lost three of their matches.
Oman and Syria are in tier five. Syria topped their group in the second round while Oman advanced as one of the best second-placed teams, the same as Vietnam.
Tier one and two boast the top teams in Asia: Japan, Iran, Australia and South Korea. Facing any of them would be a challenge for teams in other tiers.
The final round of World Cup Asian qualifiers will take place between Sept. 2, 2021 and March 29, 2022. Twelve teams in the final qualifying round will be divided into two groups of six, with the top two teams in each group qualifying directly for 2022 World Cup in Qatar, while the two third-placed teams enter the playoffs.
Video Assistant Referee (VAR) technology will be used in all 60 games of the final round, including 10 matches of Vietnam.
The draw for the final round is set to take place on July 1.
