Therefore, the team must be one of the top five at the Asian competition which will kick off in Uzbekistan on February 10.
The ideal result is a berth in the semi-final round or they must qualify for the knock-out round and have at least two wins in the play-off rounds to stand fifth.
Coach Bruno Garcia Formoso and his team left for Tashkent last week to familiarise themselves with the freezing weather and the different food and culture, which are considered big challenges for their target.
Spaniard Formoso said his players were all from the South of Vietnam where it was hot all year round while it was currently minus degrees in Uzbekistan. The early arrival would help his team to adapt to the cold.
He also wanted his players to totally focus on the game when they were away from Vietnam where their families are welcoming the Lunar New Year.
Vietnam will play Thailand, Tajikistan, and Chinese Taipei in the Group C activities.
According to Formoso, apart from Thailand which is the top Asian team, the other two are at the same level with Vietnam.
That is the main reason which the coach believes will help in accomplishing his target.
He said the first and most important task was to enter the quarter-finals. Thereafter, the whole team would plan for every step (if they have to join the play-off round for those who lose in the quarter-finals).
He said he knew the World Cup was a dream for everyone including the Vietnamese and he hoped to make it come true.
In the days in Tashkent, the coaching board has invited several teams to compete with Vietnam as warm-up activities.
In a match on February 1, Vietnam tied Uzbekistan 3-3. Their next game is against China on February 6.
The Asian Futsal Championship sees 16 participants and will close on February 21. Vietnam's best result was the quarter-final round in 2014.
