South Korea World Cup hopes in the balance after Iran draw

Syria's 3-1 victory over Qatar coupled with China's 1-0 win over Uzbekistan in Thursday's other Group A matches means a defeat for the Koreans in their final match in Tashkent on Tuesday could see them fail to qualify for the finals for the first time since 1982. 

Already having qualified from Group A, Iran played the majority of the second half at the Seoul World Cup Stadium a man down after Saeid Ezatolahi's red card.

But South Korea could not breach Iran's defence to clinch their ninth consecutive World Cup finals berth in front of more than 63,000 fans.

Second-placed Korea have a two-point lead over both third-placed Syria and fourth-placed Uzbekistan in Group A and will need to beat the Uzbeks in Tashkent on Tuesday to be sure of claiming the second automatic qualifying berth.

But should they lose then Syria could knock them out of the World Cup with a win against unbeaten Iran in Tehran. 

South Korea and Iran traded few chances in the opening half.

Tottenham Hotspur's Son Heung-Min took a free-kick from just outside the box in the 17th minute, but his low shot rolled off the leg of an Iranian player and out of play.

Midfielder Jang Hyun-Soo almost headed one in for the hosts two minutes later, but saw his attempt bounce just wide of the gaping Iranian net.

Iran recorded just one attempt on target before half-time in the 37th minute when Heerenveen forward Reza Ghoochannejhad managed to get off a shot with three defenders smothering him, though it went straight to goalkeeper Kim Seung-Gyu.

Iran were reduced to 10 men seven minutes into the second half, when Ezatolahi was shown a straight red card after he recklessly stamped on the head of Kim Min-Jae following an aerial clash between the pair.

South Korea couldn't take advantage of their extra man and wasted another free-kick opportunity in the 78th minute, when Kwon Chang-Hoon's left-footed shot from outside the right edge of the box sailed over the bar.

"We tried to turn the tide with substitutions and score a goal, but we couldn't do it," said Korean coach Shin Tae-Yong, who vowed to go all out for the win in Tashkent on Tuesday.

"We play for victories, and we will do the same for the match against Uzbekistan," Shin said.
