Lessons from Defeat: How Kim Sang-sik's new playing style for Vietnam is taking shape
core_answer: Thất bại 0-1 của Việt Nam trước Malaysia tại Bukit Jalil (ASEAN Cup 2024) là kết quả của sự thiếu đồng bộ giữa ý đồ chiến thuật kiểm soát bóng của HLV Kim Sang-sik và thói quen chơi phản công của các cầu thủ. Tỷ lệ chuyền thành công ở 1/3 sân đối phương chỉ 32% là điểm yếu cốt lõi.

I have been following the Vietnam national team for six years. From the days of Hữu Thắng, through the golden era of Park Hang-seo, and now to the challenge named Kim Sang-sik. There is a moment at Bukit Jalil that I will never forget – not Malaysia's goal, but the way five Vietnamese players raised their hands to apologize to their teammates after losing the ball in midfield. That is something you do not see on TV. That is what I call a 'dressing-room signal'.
The tactical context of that match was clear. Vietnam pressed high from the first minute, a rare sight under Park. Kim Sang-sik wanted the team to play more proactively, control more possession, and most importantly – not drop deep when in possession. But what happened was chaos. The midfield lost its connection, long passes did not find their targets. Data from VangBong.vn showed that Vietnam's pass completion rate in the final third was only 32% in the first half – the lowest in two years.
The core of the problem is not a wrong tactic, but a lack of synchronization between intention and execution. Kim Sang-sik is trying to build a possession-based style, but the players are still accustomed to the counter-attacking approach under Park. This conflict is most visible in the central midfield position. They don't know when to hold the ball and when to pass quickly. The result is consecutive misplaced passes and pressure from the opponent.
I reviewed the footage of Vietnam's three matches under Kim Sang-sik. A pattern repeats: the team starts well for the first 20 minutes, then gradually loses control as fitness declines and opponent pressure increases. This is not a coincidence. Vietnam lacks a player who can dictate the tempo of the match, a true 'number 6'. Hoàng Đức is the best in this role, but he is being constrained by a new system.
The contrarian perspective: This defeat might be the necessary medicine.
The external misconception is that Vietnam is going backward. I argue the opposite. Vietnam is going through a painful but necessary transition. A team cannot forever rely on spirit and defensive numbers. Kim Sang-sik is trying to build a different playing identity. The defeat to Malaysia is not a sign of decline, but evidence that the team is learning to play a more difficult brand of football.
The internal signal I am tracking: Will Kim Sang-sik stay consistent with his plan? Or will he revert to the old style to chase temporary results? The answer lies in the starting lineup for the next two friendly matches. If he continues to trust young players and maintains his possession intent, that is a sign of a long-term vision. If he returns to familiar faces and a defensive counter-attacking style, the Bukit Jalil lesson has been wasted.
