SEOUL, Sept. 1 (Xinhua) -- Iran kept their unbeaten run in the 2018 World Cup qualifier after they drew 0-0 at the Seoul World Cup Stadium on Thursday.
Iran have not conceded a goal in their nine appearances in the 2018 World Cup qualification.
Just 10 minutes into the second half, Iran midfielder Saeid Ezzatollahi was shown an early red card for kicking Kim Min-jae but the hosts were unable to capitalize on their advantage.
Iran, who have already secured a slot at next year's World Cup finals in Russia, will host Syria in Tehran's Azadi Stadium five days later, while South Korea play Uzbekistan in Tashkent. A draw could secure South Korea a place in the FIFA World Cup for the ninth consecutive time.
Iran are on top of Group A with 21 points, seven points above the second-placed South Korea.
Iran were the first team to leave South Korea with a point during qualification for Russia 2018.
