Vietnam U-23 will play the final test against Palestine U-23 ahead of the AFC U-23 Championship in China next month.
The team will reportedly leave for China on the first day of January, eight days before the tournament begins.
After a three-day training session, coach Park Hang Seo and his side will take on the last test against Palestine U-23 before the tournament kicks off.
The 28 players have been training for nearly a week in Hanoi before coach Park officially selects 23 players to compete at the regional competition.
Vietnam have been drawn in Group D with title favorites South Korea, Australia and Syria.
