Vietnam defeated Malaysia 2-1 in the first leg of the AFF Suzuki Cup semi-final clash at Shah Alam Stadium on Sunday.
Chinese referee Ma Ning awarded the home team a controversial penalty in the 13th minute, insisting that Huy Hung deliberately played the ball with his hand.
Safiq Rahim did not miss the chance to help Malaysia take an early lead.
According to Nguyen Van Mui, head of Vietnam football referees' committee, the penalty was controversial and may have stemmed from pressure from the home team.
Despite the pressure, Vietnam continued to attack and Huy Toan equalized the score after receiving a ball bounced out from Malaysian goalkeeper Khairul from a shot by Van Quyet.
In the 59th minute, Mac Hong Quan was sent to the match and he quickly had a good pass for Van Quyet to score the second goal for Vietnam.
On Saturday night, the first leg of the other semi-final match between the Philippines and Thailand, which went ahead despite fears over Typhoon Hagupit, ended in a goalless draw in Manila.
In the second leg, Thailand will host Philippines at 7 pm on December 10 while Vietnam will play Malaysia at 7 pm on December 11 at Hanoi’s My Dinh Stadium.
The News Straits Time Online said Sunday that "Malaysia will head to Hanoi with an impossible mission".
"With a poor away record in Vietnam, it looks like Malaysia will have to work hard to turn the tables in the return leg in Hanoi," it said.
