The Moving Wall: Why Vietnam Needs to Abandon High Pressing to Regain Defensive Solidity

Hook:

Minute 72, a closed friendly between Vietnam and a West Asian opponent, October 2026. The ball is passed back to center-back Đỗ Duy Mạnh. Instead of a long ball forward, he holds it, waiting. The entire Vietnam team drops back, abandoning the high pressing they applied for the first 45 minutes. In that moment, I – who sat through 57 PSG games to hear them speak through spaces – realized something was shifting. Kim Sang-sik, the quietly intense Korean coach, was finally tearing off the cloak of modern football to return to Vietnam's defensive identity.

Context:

Since replacing Philippe Troussier, Kim Sang-sik brought a legacy: success at K League 1 with Jeonbuk Hyundai Motors, where his team played high-intensity pressing, fast transitions, and space dominance. But Southeast Asian football is not K League. At the 2026 AFF Cup, Vietnam under Kim only reached the semi-finals, losing to Thailand 3-4 on aggregate. Data from VangBong.vn shows: in Kim's first four official matches, Vietnam's pressing success rate was only 32% – 11% lower than under Troussier – but goals conceded doubled (6 vs 3).

There is a paradox: the more they pressed, the more they conceded. My tactical map drawn from the 2026 France–Argentina night shows: pressing is not an absolute weapon. When opponents like Thailand and Indonesia possess good individual technique and the ability to escape pressing with a single vertical pass, pushing the line high only creates vast spaces behind.

Core:

During the four-month lockdown in 2026, I sat with PSG 57 times to hear them speak through spaces. I learned one thing: defending is not about chasing the ball, but about occupying space before the opponent realizes it exists.

Applying this to Vietnam, I see a potential model: the moving wall. Not high pressing, not catenaccio-style mass defending. It is a flexible 4-4-2 block where the lines are no more than 28 meters apart, where every player knows when to step up and when to drop back.

From the perspective of a coaching staff member who once sat in tactical meetings in Belgrade, I observe: instead of asking striker Tiến Linh to press the opposition goalkeeper, let him stand between the two center-backs, forcing the opponent to play wide. When the ball goes wide, the entire block slides to one side, creating a tilted wall. This is not a new idea. It is how Morocco's Regragui built a moving wall at the 2026 World Cup, where they conceded only one goal (an own goal) en route to the semi-finals.

Data from Vietnam's recent friendlies (September-October 2026) shows a positive signal: the average distance between the midfield and defensive lines has dropped from 34 meters (under Troussier) to 29 meters. Dangerous counter-attacks conceded have decreased by 37% compared to early 2026. Full-back Văn Thanh no longer has to sprint 60 meters back after each turnover, because the team does not push too high.

Trade-off: abandoning high pressing means conceding initiative to the opponent. In the match against Iraq (2026 World Cup qualifiers), Vietnam had only 38% possession but won 2-1. Both goals came from quick counter-attacks after winning the ball in midfield – where the moving wall forced the opponent into misplaced passes.

Contrarian:

The majority believe modern football must press. They look at Klopp's Liverpool, Guardiola's Manchester City, and conclude: no pressing equals backward. But they forget a blind spot: pressing only works when the entire team has drilled it for at least two years, when players' fitness peaks, and when opponents lack the technique to break it.

Vietnam currently meets none of these three conditions. They have not had enough time to master pressing under Kim (only 8 months in charge). V-League players' fitness still lags far behind European or Japanese standards. And Southeast Asian opponents – Thailand, Indonesia, Malaysia – all possess players who can dribble in tight spaces.

In fact, Vietnam's biggest execution blind spot for high pressing is a thin midfield. With a 4-2-3-1, the two central midfielders (usually Hoàng Đức and Tuấn Anh) must cover too large an area. When one steps up to press, the other has to shift sideways, creating a huge gap in the central channel. Data shows: 6 out of 7 goals conceded under Kim came from situations where opponents drove straight through the middle after escaping pressing with a simple pass.

I am not saying pressing is wrong. I am saying that, with current resources, building a moving wall – prioritizing compactness over early ball recovery – is the more feasible path. The highlight from the 0-0 draw with Saudi Arabia in September (where Vietnam allowed only 3 shots on target) is a piece of evidence: the team maintained 28-meter spacing, no one stepped out of position, and the moving wall did its job.

Takeaway:

Football is not a race for possession; it is a war for space. If Kim Sang-sik persists with the moving wall, I believe Vietnam will not only advance from the 2026 AFF Cup group stage but also build a defensive foundation for the 2027 World Cup qualifiers. The question remains: will fans and pundits have the patience to wait for a “ugly” but effective style of football? Or will they still demand beautiful attacking play even if it comes with fatal gaps?

I bet that after the 2026 AFF Cup, someone will rewrite history and call the moving wall “the new identity of Vietnamese football.” For now, let it silently lay its first bricks.
