However, the Afghanistan team did not let that happen, holding Vietnam to a goalless draw in the Group C of the 2019 Asian Cup qualification on November 14 in Hanoi.
The visitors did an even better job than what their coach Otto Pfister had planned.
Prior to the game, German Pfister did not show much appreciation for Vietnam who were No 121 in the world, some 30 steps higher than his team.
He said that even with new coach but the same players Vietnam would not be very different from those who drew 1-1 with his team months ago in the first leg match.
He was right.
Park had been working just a month since he signed a contract with the Vietnam Football Federation and only one week to gather players based on the advice of the former coach Mai Duc Chung and the VFF’s coaching council.
The expert from the Republic of Korea said his team was ready to beat Afghanistan but in fact it was a match that the hosts had to resist strong attacks from the visitors who were better in both speed, form and physique.
Just eight minutes after the first whistle, Zubayr Amiri nearly opened the score with a powerful header but goalkeeper Nguyen Tuan Manh stopped it.
Midfielder Dinh Thanh Trung of Vietnam answered with a free kick straight to the net but he could not beat goalie Hamidullah Wakili.
Striker Nguyen Cong Phuong had a low pass to the box but his teammates could not convert it an opener.
Afghanistan played a pressing game at high speed when it was half way into the first half. They had two chances by Haroon Fakhrudin and Milad Salem near the break but keeper Manh denied all.
The second half was even worse for the hosts when they had to resist consecutive attempts from Afghanistan, especially in 10 last minutes. Meanwhile the host strikers could not find any hole to dig into Wakili’s area.
Amiri again almost made more than 8,000 Vietnamese supporters in the stands hold their breath with his shot that hit the right post in the 85th minute.
From that moment to the end, Vietnamese players played a defensive game trying to ensure a draw. Striker Nguyen Anh Duc received a yellow card for time wasting.
“It is a pity that we could not grab three points from this match. My players did not play as well as they did in training,” Park said at the post-match conference.
“I had to suffer a little pressure in this match, but I and my players worked hard for the game. (A draw) is an acceptable result because we have earned the (Asian Cup) slot. We need more time together and players could familiarise themselves with a new playing style,” said Park who finally thanked his players for their performance on November 14.
“I am not happy with the result of the match because in 90 minutes Vietnam had only one threatening chance but Afghanistan had four clearly opportunities,” said Pfister, who congratulated Vietnam for their berth in the Cup finals.
With one point from the game, Vietnam are placed second in the group with nine points. Jordan who beat Cambodia 1-0 in an early match at the National Olympic Stadium in Phnom Penh take the top with 11.
Jordan and Vietnam sealed their berths at the Cup finals which will be held in the United Arab Emirates in 2019.
It was the best ever result for Vietnam as it was their first official ticket of the team. Earlier, they had a chance to compete in the Cup in 2007 as the hosts.
The top two teams will play each other in the last group round match on March 27. However, the result of the game is just to identify the group’s leading team.
