Vietnam were considered contenders for the crown in 2012 but were knocked out of this year's tournament at the first hurdle by finishing second from bottom in Group A.
Disappointingly for the footbal-mad public in Vietnam, the Red Warriors managed only a measly point - a 1-1 draw with Myanmar in their opener - and were beaten by eventual qualifiers Philippines 1-0 in the next game.
Facing a must-win match against Thailand in the final group game, Thanh Hung's tactics came under the spotlight when he dropped star striker Le Cong Vinh and played with six midfielders. The move did not pay dividends as they fell 3-1 to the Thais, who topped the group, leaving Vietnam to exit the Suzuki Cup before the semis for the first time since 2004.
However, Le Bang, who is also the general secretary of the Vietnam Football Federation, insists Thanh Hung's role with the national team remains safe.
"We have signed a contract with him [Thanh Hung] until December next year," he said on the AFF Suzuki Cup website.
"We will not fire him, we trust him. But, of course, he may resign."
He added: "I am not superstitious but we have had a lot of bad luck [in this year's tournament]."
"Many of our best players were injured and when we came to Bangkok others fell ill or were also injured. We have changed all our defenders since the 2008 and 2010 AFF Suzuki Cups.
"Still it is the coach and management's responsibility that the team underperformed."
Vietnam won the competition in 2008.
