From AFF Cup 2026: Has Vietnamese Football Truly Escaped the 'Shadow' of Defensive Play?

On the night of January 5, 2026, at Rajamangala Stadium, when Nguyen Tien Linh headed the ball into the Thai net in the third minute of stoppage time, I didn't shout like my colleagues around me. I just silently watched the livestream screen, where the comment feed was rolling like a waterfall. In that moment, I remembered a phrase I once said during the 2026 World Cup: "Livestream is where hearts are laid bare." And the heart of an entire nation was being laid bare in that cramped frame – not passion, but a fear hidden for 10 years: the fear that we only knew how to defend, the fear that the 2026 victory was just a lucky dream.

But when the ball stopped, when the final whistle blew, I realized I was wrong. Not because Vietnam won, but because of how they won. Coach Kim Sang-sik's team didn't defend. They attacked. They pressed. They dared to play the kind of football we only dared to dream about 10 years ago. And the question now isn't "have we escaped the shadow of defensive play," but rather: why did it take us 10 years to realize we could do this?

The context of this final wasn't easy. Thailand, the defending champions of two consecutive AFF Cup titles, boasted a squad with players plying their trade in the J.League and K.League. They had Chanathip Songkrasin, Theerathon Bunmathan, and a pedigree that Southeast Asian football had to respect. Vietnam, meanwhile, arrived at this tournament amid skepticism: Coach Kim Sang-sik had only been in charge for a few months, the playing style wasn't yet defined, and pre-tournament friendlies were unconvincing. Experts, including myself, predicted a familiar script: Vietnam would play defensive counter-attacking football, wait for opponent mistakes, and hope for set-piece opportunities.

But from the semi-final against Singapore, I saw something different. Vietnam didn't sit deep. They pushed their line high, pressed from the opponent's half, and most importantly – they dared to keep the ball. In the first leg of the final at Viet Tri, against a Thailand side rated higher in class, Vietnam maintained astonishing composure. The 52% possession in the first leg isn't the number of a defensive team. It's the number of a team that dares to confront.

This systemic change didn't come from one individual, but from a philosophy clearly transmitted by Coach Kim Sang-sik. Unlike his predecessor Park Hang-seo, who built success on defensive solidity and discipline, Kim Sang-sik brought a completely different mindset: ball possession is the best defense. He didn't ask his players to run more; he asked them to think faster. This was most evident in how Nguyen Quang Hai was utilized.

Quang Hai, a player once criticized as "past his prime" after unsuccessful stints in France and Switzerland, was resurrected spectacularly. In Kim Sang-sik's system, Quang Hai is no longer a free-roaming attacking midfielder as under Park Hang-seo. He became a modern number 8, connecting midfield and attack, responsible for dictating the game's tempo. Quang Hai's average touches in the second leg of the final were 78 – the highest in the team, and more importantly, 85% of those were short, safe passes that helped the team maintain continuous attacking rhythm.

But if it were only Quang Hai, nothing would have worked. The key lies in Kim Sang-sik's courage to use young players. Nguyen Dinh Bac, 20, was trusted to start in both finals. Nguyen Van Truong, 21, came off the bench and made a difference with intelligent decisions. This is something Park Hang-seo rarely did – he always prioritized the safety of experienced players. Kim Sang-sik is different. He sees potential, and he dares to bet on it.

Tournament data shows a clear shift: Vietnam had the highest average passes per game with 412, far exceeding their own 287 at AFF Cup 2026. Average shots per game also increased from 9.2 to 14.6. But the most impressive number is goals from short-passing combinations: 7 out of 12 tournament goals, compared to just 2 from set pieces. This indicates a complete transformation in attacking philosophy – from relying on individual moments of brilliance to an organized collective style.

However, I'm not someone who only praises. I've witnessed too many times Vietnamese football soaring then falling. And I see a dangerous blind spot in Kim Sang-sik's tactics: over-reliance on the fitness of key players. In the second leg of the final, Nguyen Hoang Duc ran a total of 12.4 km – the highest in his career. But at minute 80, when Thailand pushed forward, Hoang Duc no longer had the energy to press. If the match had lasted 10 more minutes, would the result have held?

This is the question I believe Coach Kim Sang-sik needs to answer in the coming period. Modern football isn't just about how well you play in the first 70 minutes, but how you survive the last 20. The 5-substitution rule helps deeper squads, but it also turns the final 20 minutes into a war of attrition. And in that war, Vietnam is still too thin in some positions.

But perhaps I'm being too harsh. Because the most important thing AFF Cup 2026 brought isn't tactical – it's psychological. This generation of players has proven they aren't afraid of Thailand. They aren't afraid of keeping the ball. They aren't afraid of attacking. And that, in my view, is more valuable than the championship trophy itself.

I remember the summer of 2026, when football was halted due to COVID-19, I wrote an article about FIFA Online 4 titled "Pep Guardiola Should Play FIFA Online 4 to Understand Why Tiki-taka Is Dead." That article went viral because it spoke a truth many didn't dare admit: world football has changed, and teams that refuse to change will be left behind. Vietnamese football has changed. The question is: is this change sustainable?

I believe it is, but only if we see the problem correctly. Winning AFF Cup 2026 isn't the destination; it's the starting point. It shows potential, but potential only becomes reality when nurtured by a proper youth development system, modern facilities, and a truly professional football environment. Otherwise, we'll fall back into the cycle of ups and downs – winning then declining, hoping then despairing.

An empty stadium doesn't cool the match; it only makes emotions burn brighter. And the emotion of Vietnamese fans after the night of January 5, 2026, is special – not just the joy of victory, but the pride of seeing their team play the football they've always dreamed of. I write hot takes so that in the future, I can look back and see that I once had fire in my blood. And today, I have fire for a legitimate reason: Vietnamese football dared to dream, and dared to turn that dream into reality.

But I still have one final question, a question I think every fan should ask themselves: If not for Kim Sang-sik, would we have dared to play this way? And if the answer is no, then what do we need to change to not depend on any single individual? Because a strong football nation isn't built on a talented coach, but on a solid system. And that is the real challenge ahead.
