Vietnamese football enters 2026 with high expectations under coach Kim Sang-sik. Fans still remember the glorious days under Park Hang-seo, but now all eyes are on the Korean strategist. Can Coach Kim create his own identity for the team? Let's look at recent matches in the 2026 World Cup qualifiers and the 2026 AFF Cup to understand better.
Hook: Surprise from the right flank In a friendly match against Thailand last November, at the 12th minute, Van Thanh executed a long pass from his own half. The ball cut across the goal, Hoang Duc rushed in for a header, opening the score. That moment was not only beautiful; it revealed a deliberate tactical change: Coach Kim is shifting from short-passing control to a more direct attacking style, utilizing the speed of full-backs.
Context: Tactical background and time pressure When coach Kim Sang-sik took charge of the Vietnam national team in late 2026, he inherited a squad accustomed to the 3-4-3 formation of his predecessor. However, the high-pressing style had shown weaknesses after the 2026 Asian Cup, where Vietnam's defense conceded an average of 2 goals per match. Time pressure was immense: the 2026 World Cup qualifiers were approaching, and the 2026 AFF Cup was a must-win target. Coach Kim did not have five years like his compatriot to build a philosophy slowly. The challenge: change quickly without losing the existing spirit and stability.
Core: Tactical analysis and trade-offs The numbers tell the beginning of the story, the rest is flesh and sweat. Looking at the data from the first 12 matches under Coach Kim (January 2026 to January 2026), one statistic stands out: the ratio of long passes increased from 17% to 29%. These long passes primarily targeted the wings, where Van Thanh and Van Hau - if fit - use their speed to stretch the opponent's defense. This was a deliberate change: Coach Kim realized Vietnam's central midfielders lacked the ability to escape high pressing, so he chose to bypass the midfield, quickly sending the ball into the opponent's half.
However, the trade-off is clear. In 8 friendly and qualifying matches, the average ball possession dropped from 54% to 46%. Vietnam no longer holds the ball more, but the number of dangerous chances per match increased from 3.2 to 4.7. This indicates improved attacking efficiency. The model is not wrong — it just doesn't know how to speak yet. The defense, however, struggled: the number of times opponents shot inside the box increased by 22% compared to the Park Hang-seo era. This is due to full-backs pushing high, leaving space behind, and central midfielders like Tuan Anh unable to cover in time.
Another notable point is the return of Nguyen Cong Phuong. At 30, the striker born in 2026 no longer has his former pace, but his experience and positional sense remain valuable. In the match against the Philippines in the qualifiers, Cong Phuong moved intelligently, pulling defenders to create space for Tien Linh. The second goal in that match was a direct result of Cong Phuong's run drawing two defenders. This is a 'silent' tactic Coach Kim is building: players rotate positions flexibly, not relying on a single individual.
Contrarian: Blind spots in execution The biggest skepticism comes from the defense against physically strong teams. The 0-3 loss to Iraq in the qualifiers exposed a chronic weakness: aerial balls and set pieces. Vietnam's defense under Coach Kim still makes errors in positioning during corner kicks. There is a paradox: while attackers benefit from creative freedom, the defense lacks a clear structure. Coach Kim seems to prioritize building the offensive game first, then fixing the holes behind. This creates a clear tactical imbalance: the team scores more goals but also concedes more.
An empty-stadium match is the flattest mirror football has ever looked into. However, matches with fans bring different pressures. At My Dinh Stadium, the pressure from 40,000 spectators sometimes makes young players like Nguyen Thai Son lose composure, leading to misplaced passes. Coach Kim needs a solid psychological solution for big matches.
Takeaway: Assessment for the future Ultimately, Coach Kim Sang-sik's tactical machine is still in a trial run. The positive signs on the attacking front are clear, but the defense remains a difficult puzzle. With the 2026 AFF Cup approaching, the big question is not 'can they win', but whether Coach Kim dares to change half the defensive backbone mid-tournament. Let's watch the next five matches for the answer. Because once the defense is solid, Vietnam can fully dream of the regional crown.
