When a team is relegated, I draw the diagram of pain. But for the Vietnam National Team under coach Kim Sang-sik, the pain doesn't come from points – it comes from the gaps in how the system operates.
I remember the AFF Cup 2026 second-leg final at Rajamangala Stadium. Minute 67, Thailand counter-attacked from a Vietnamese throw-in on the right flank. Quang Hải lost the ball in midfield, and within 7 seconds, it was in Nguyễn Filip's net. I noted: from the turnover point to the goal, there were 4 passes, and 3 Vietnamese players were out of the frame. That was when I realized: there is a hidden flaw in the deep defensive system that no one talks about.
Tactical Context
Coach Kim Sang-sik took over in May 2026, replacing Philippe Troussier. He brought a philosophy of controlled high pressing – a 4-3-3 that morphs into 4-1-4-1 out of possession. In the AFF Cup group stage, Vietnam conceded only 2 goals in 4 matches. But against Thailand in the final, everything changed. The midfield trio of Hoàng Đức, Thái Sơn, and Nguyễn Quang Hải were overwhelmed by the pressure from Chanathip and Supachok. Data from both finals shows: Vietnam's pass completion rate in their own third dropped by 12% compared to the group stage, and dangerous turnovers in midfield increased by 40%.
The meeting room has no windows, so I write to see what I am saying. I rewatched both matches, placed the formation on the board, and began drawing the passes, the pressing points, the spaces invisible to the naked eye. From there, a tactical picture gradually emerged.
Core Analysis: The Pressing System and Midfield Gaps
Under Kim, Vietnam uses mid-block pressing triggered when the opponent touches the ball in the middle third. The idea is to push opponents wide, then trap them offside or regain possession via center-back interceptions. However, the problem lies in the coordination between the midfield and defensive lines.
In the first leg (a 1-1 draw at Mỹ Đình), I counted 11 instances where Vietnam's central midfielders – mainly Hoàng Đức and Thái Sơn – pushed too high relative to the back four, creating a gap wider than 15 meters in the central channel. Thailand exploited it immediately: Supachok received the ball in that pocket, turned, and played 3 line-breaking passes leading to Teerasil's opening goal. That was not an individual error – it was a systemic one.
I call it the 'double corridor syndrome': when both central midfielders press simultaneously while the full-backs haven't tucked in, the entire zone in front of the penalty box becomes dead ground. In the second leg, Kim tried to fix this by dropping Tiến Linh deeper to assist defensively. But Tiến Linh – a natural striker – lacks the habit of reading defensive situations from distance. He often gets drawn to the ball, neglecting his position in the central channel.
Tactics cannot save a team, but they help you know where you die. I compiled a data table of 23 dangerous turnovers by Vietnam in both finals. Result: 14 came from the zone in front of the box, 9 from Thailand's left flank. Of those, 8 led to clear goal-scoring chances. The common denominator: all originated from uncoordinated pressing between lines.
Contrarian Angle: What if Vietnam Didn't Press?
Many argue pressing is essential against Thailand. But I reverse the question: what if Vietnam deliberately dropped deep, surrendered possession, and played with a compact block? Data shows that in 4 group-stage matches against weaker opponents (Laos, Cambodia), Vietnam pressed successfully and held 65% possession. But against Thailand, the pressing success rate dropped to 31%. This suggests pressing is not an optimal weapon against a team with Thailand's ball circulation ability.
I revisited Park Hang-seo's matches from 2026-2026. Back then, Vietnam often sat deep, using a 3-4-3 or 5-3-2 to close every gap. The 1-0 win over Thailand in AFF Cup 2026 is a textbook example: a 5-man defense, no high pressing, just waiting for opponent errors. In contrast, under Kim, Vietnam presses 40% more than under Park. This shift reflects an adaptation to modern football, but is it suitable for the current squad?
Execution Blind Spot: Vietnamese players lack the speed and stamina to sustain high-intensity pressing for 90 minutes. In the second leg, after minute 70, metrics for distance covered and tackles dropped sharply. Thailand scored the decisive goal in the 83rd minute – a central combination play where no Vietnamese player had enough energy to cover.
Progressive Takeaway: Post-Match Verification
I am not saying pressing is wrong. But without adjustments in timing and intensity, Vietnam will keep conceding in the same pattern. The friendly against India in October 2026 (Vietnam won 3-1) was a positive signal: Kim had the team drop deeper after taking the lead, reducing pressing to 25% and playing counter-attacking football. Result: India managed only 2 shots on target in the second half.
I will monitor Vietnam's next 3 matches in Asian Cup 2027 qualifiers to verify: will Coach Kim maintain that tactical flexibility? Will the midfield be reinforced with a proper defensive screener? The empty-stadium summer of 2026 taught me that applause is just a coat of paint. Beating India proves nothing. The real test comes when the opponent is stronger and the pressure is higher. That is when the tactical map reveals where not to stand.
