Yangon: Host nation Myanmar edged into the AFC U-19 Championship quarter-finals as Group A runners-up despite losing 2-0 to already eliminated Iran at Thuwunna Youth Training Centre Stadium on Monday, qualifying courtesy of a better goal difference than Yemen who lost 3-2 to Thailand in the other Group A clash played in Nay Pyi Taw.

Iran rang the changes, making five alterations to the line-up that were eliminated in the 1-0 loss to Yemen on Saturday, and it was the introduction of two of these new faces, Yousef Seyyedi and Sadegh Moharrami, that were key as they netted the goals for the West Asians on the 55th and 82nd minutes.

And although the home side looking nervously northwards towards Nay Pyi Taw, they were able to scrape into the knockout stage by the narrowest of margins with a one goal superior goal difference over Yemen.

"We are happy for our qualification but an easier opponent than Iran will not come," said Myanmar's coach Gerd Zeise.

"Our goalkeeper was our man of the match, he was very safe, very good, without him we would have been in trouble. "On the right hand side we had some problems but who should I substitute? There is no one this is our disease, we have 11 good front line players then it is difficult, very difficult."

Myanmar attacked from the start and in a manner that was full of energy but occasionally lacked control as displayed when Than Paing took the ball from the sideline and beat two Iran defenders for pace but let the ball get away from him, making it easy for goalkeeper Payam Niazmand to collect.

Iran finished the half strong, though, with a number of opportunities to open the scoring, and on the 36th minute Hossein Mehraban was left alone, unmarked, just outside the penalty area but could only hit the ball high over the crossbar under pressure from Myanmar defenders.

Early in the second half Ali Gholizadeh forced a fine 53rd minute save at the near post from Myanmar's Myo Min Latt and from the resulting corner the custodian once again intervened to give Nanda Kyaw a chance to clear the ball off the line.

But the danger was only momentarily abated as the ball was played back into the box and Seyyedi finished clinically to put Iran into the lead five minutes before the hour-mark.

The game picked up its tempo from then on, though, and a header from Than Paing from a corner forced Niazmand into sound stop but the next attempted set-piece resulted in an Iran counter that saw Mehraban force yet another accomplished save from Myo Min Latt.

But Myanmar's hopes of a comeback were quashed eight mintues from time, when the ball bounced free from a melee in the box and towards Moharrami who hit the ball low and hard across Myo Min Latt. The keeper got a glove to the ball but was only able to force it on to the inside of the post to give Iran their second.

Myanmar were then forced to endure a nervy final ten minutes with the news of Thailand's spectacular comeback against Yemen filtering in, with the significance of the scoreline in Nay Pyi Taw meaning that conceding a third would have resulted in the hosts facing the possibility of elimination from the tournament.

To the relief of the players and their massed ranks of fans, though, they were able to hold out and will now face the winners from Group B on Friday; that opponent to be determined in Tuesday's matchups.

"I was sure we could qualify with nine points, but it wasn't to be," said Iran coach Ali Doustimehr.

"I believe Myanmar have the coach, the players and the tactics to reach the semi-finals."
