Thailand secured their place in the AFF Suzuki Cup semi-finals after beating Myanmar 2-0 on Saturday.
Myanmar needed to beat Kiatisuk Senamuang's side by at least two goals to have a chance to advance to the last four as Group B runners-up, but were left wondering what might have been after stunning strikes from Tanaboon Kesarat and Prakit Deepromwere settled the contest in Thailand's favour.
The three-time AFF Suzuki Cup champions will now go on to face Philippines in a two-legged semi-final, with the first leg taking place on December 6.
For Myanmar, it was a match of missed opportunities after the 21-year-old striker Kyaw Ko Ko missed several guilt-edged opportunities in front of goal.
After Kyaw missed an open goal with a cushioned header, Tanaboon was set up by Sarawut Masuk at the opposite end and his 11th minute thunderbolt from 22 yards gave the former champions the lead somewhat against the run of play.
Despite going behind, Myanmar continued to create the better opportunities, but Kyaw's horror show in front of goal continued to frustrate the vociferous Myanmar fans.
In the 58th minute, Raddy Avramovic's side seemed destined to equalise but Kyaw's chip cannoned back off the cross-bar and goalkeeper Chanin Sae-Eae was able to smother the loose ball.
Myanmar then paid the ultimate price for the striker's profligacy in front of goal when Prakit's sweetly struck free-kick from 25 yards out in the 83rd minute handed Thailand a 2-0 advantage and with that, the match.
