Iran beats Vietnam 2-0 for 2nd win at Asian Cup
With two wins each, Iran and Iraq meet in Dubai on Wednesday to decide the group winner.
Saudi Arabia meets Qatar on Thursday to close the group stage in a highly charged game amid the political tensions between the two nations.
The top two teams in each group and the four best third-placed teams advance to the round of 16.
It was a record ninth successive victory for Iran in Asian Cup group matches. Asia’s top-ranked team has dominated possession and looked comfortable in its opening two games, scoring seven goals without conceding.
Iran’s Sardar Azmoun took care of the goals against Vietnam, scoring in each half.
Saman Ghoddos crossed for the forward to put Iran ahead with a close-range header before halftime. Azmoun added his second in the 69th with a left-footed strike from the middle of the box for his third goal at the tournament.
Vietnam lost a second straight match after falling to Iraq 3-2.
In Sharjah, Mohanad Ali Kadhim and Bashar Resan Bonyan scored with low shots from outside of the area early in the first half to give Iraq a comfortable advantage against Yemen. Substitute Alaa Abbas sealed it in second-half injury time.
Yemen and Vietnam are pointless and will fight for third place in Al Ain on Wednesday.
With two wins from two, Saudi Arabia leads Group E with six points and could advance with a game in hand if North Korea fails to beat Qatar on Sunday.
Saudi Arabia won its opening two games at the Asian Cup for the first time since 1996, when it last won the title.
After two defeats, Lebanon faces a must win against North Korea to have a chance to make it to the next round.
