The United Arab Emirates handed South Korea a surprise 1-0 defeat in Dubai on Tuesday to set up a playoff clash with Australia as they kept alive their hopes of a first World Cup appearance in 32 years.
Hareb Abdalla's 54th minute goal sealed a third place finish in Group A for Rodolfo Arruabarrena's side, ensuring the UAE will take on the Socceroos in a one-off meeting in Doha on June 7.
The winner of that match with then face the fifth-placed team in the South American qualifiers with a berth in the finals in Qatar at stake.
Abdalla struck against the run of play for the Emiratis, who were facing a Korean side that had not conceded a goal in their previous five qualifiers and were looking for a victory that would secure them top spot in Group A.
Striker Hwang Hee-chan hit the woodwork in the first half as the Koreans dominated but, nine minutes after the restart, Abdalla scored.
The 19-year-old, deputizing for suspended first-choice forward Ali Mabkhout, latched onto Mohammed Al Baloushi's pass and calmly stroked the ball past Jo Hyeon-woo.
South Korea hit the frame of the goal again six minutes later when Hwang Ui-jo's header clipped the top of the bar but they could not deny the UAE, who are looking to qualify for the finals for the first time since making their debut in 1990.
The Emirates finished in third place in the group ahead of Iraq, who were held to a 1-1 draw by Syria.
Abdulghani Shahad's side needed to beat the Syrians and hope the UAE lost to South Korea, only to go behind in the fourth minute when Alaa Al Dali shot into the roof of the net.
Aymen Hussein headed in an equalizer 14 minutes before the break to give his side a lifeline but the Iraqis were unable to claim a second win in the qualifiers.
Iran earned a 2-0 win over Lebanon in Mashhad through goals from Sardar Azmoun and Alireza Jahanbakhsh to ensure Dragan Skocic's side finished on top of Group A, two points ahead of the Koreans.
In Group B, Japan defender Maya Yoshida's second-half goal earned a 1-1 draw with Vietnam at Saitama Stadium as Hajime Moriyasu's World Cup-bound side brought down the curtain on their preliminary campaign.
The Japanese team, who confirmed their place at a seventh consecutive World Cup finals with victory over Australia on Thursday, were forced to fight back after Nguyen Thanh Binh's 19th minute header had given the visitors the lead.
However, Yoshida scored from close range nine minutes into the second half to earn a much-changed home side a share of the points.
