Defender Dinh Dong Tran botched his clearance of a cross, knocking it onto the post, which confused goalkeeper Nguyen Manh Tran enough to allow Stefano Lilipaly to prod home for the opening goal in the second leg of their AFF Suzuki Cup encounter.
The keeper's game got even worse as he later saw a straight red card and, despite Vietnam forcing extra time, his side ultimately lost out.
