FFA Technical Director Peter de Roo said: "Good result against Philippines, but our performance was still not up to our expectations or the standard that we know the players are capable of.
"Again there was poor decision making and too many easy turn-overs. Two must-win games coming up against Singapore and Malaysia to give us a chance to make the semi-finals.
"This would give us an extra two matches in this tournament, which we see as crucial learning opportunities."
Joeys coach Tony Vidmar added: Happy with our performance against Myanmar – we played with the right intent and the way want to play. We had plenty of chances – it was the execution which let us down.
"The pitch was in a very poor condition, especially through the centre and in the goal areas – which did make it difficult.
"Our performance against Vietnam was unacceptable. Poor decision-making lead to easy turnovers, we essentially gave them goals. We were also unable to create scoring opportunities of our own."
