Viet Nam lost to Hong Kong 1-0 in the Asian Cup 2015 qualifier at Mongkok Stadium on Friday.
Chan Wan Ho's goal helped the hosts earn three points.
To prepare for the away match, coach Hoang Van Phuc's players produced an impressive 4-1 performance in their warm-up game against Ha Noi T&T several days ago.
Viet Nam were on the attack from the kick-off, but failed to take advantage of their possession. In the final minutes, Hong Kong pushed forward and were rewarded by Chan's header that sealed the win for Hong Kong with three minutes to go.
After two losses, Viet Nam remain bottom of Group E. — VNS
