Two Contrasting Squad-Building Models: The Cong - Viettel and Cong An Ha Noi

Some matches tell their entire story through the team sheet alone. That afternoon at Hang Day, my notepad held only two columns of names. On the left, The Cong - Viettel fielded two foreign centre-backs — Kyle Colonna and Paulo Martins — sitting directly in front of the goalkeeper. On the right, Cong An Ha Noi rolled out a vertical spine of faces freshly returned from national-team duty: Nguyen Filip in goal, Bui Hoang Viet Anh at the heart of defence, Nguyen Dinh Bac and Nguyen Quang Hai further forward. In midfield, Stefan Mauk partnered Le Pham Thanh Long.

I have watched youth and domestic football long enough to know that line-ups like these do not form inside a single transfer window. They are the product of choices accumulated over years. And in the derby between the army club and the public-security club, those two sets of choices collide.

Context: two sources of capital, two ways of spending

V.League 1 does not operate under a UEFA-style financial fair play system. Here, money is rarely policed by rulebook — it is policed by ownership structure. The Cong - Viettel belongs to Viettel Group, a defence enterprise with steady cash flow but disciplined spending. Cong An Ha Noi is backed by the Ministry of Public Security, a resource capable of concentrating expenditure on major deals. These are two different types of capital, not merely two different amounts.

That difference shows immediately on the pitch. While Cong An Ha Noi accumulates proven national-team players, The Cong - Viettel remains loyal to a traditional academy pipeline and tops it up with moderately priced foreign defensive signings. This is not a question of better or worse. It is two philosophies.

One caveat must be stated up front: this article contains no xG data, no PPDA figure, no possession statistics. Every conclusion below rests on personnel and on how the two clubs position themselves. That is a limit worth being transparent about, because tactical analysis without data is discipline, not certainty.

Core insight: a foreign foundation against a domestic star spine

The core difference is this: one side builds from a foreign defensive foundation, the other from domestic stars.

Look at The Cong - Viettel's vertical axis. Kyle Colonna and Paulo Martins form a foreign centre-back pairing. That is the kind of personnel choice that signals a safety-first approach at the back, prioritising solidity before committing to attack. When the army club places two foreigners in defence, the message is clear: they want a stable base from which to transition quickly, rather than imposing the game through sustained possession.

This aligns with how the media frames Andre Luiz and Doan Ngoc Tan: they are expected to help The Cong - Viettel compete and transition better. The keyword sits right there. A midfield described by transition capacity rather than control capacity is usually the midfield of an organised counter-attacking side. It is unglamorous football, but durable football.

On the other side, Cong An Ha Noi takes the opposite route. The club assembles a national-team spine stretching from goal to attack: Nguyen Filip, Bui Hoang Viet Anh, Nguyen Dinh Bac, Nguyen Quang Hai. Add Stefan Mauk and Le Pham Thanh Long in central midfield and they possess a vertical axis that both controls and screens. Mauk — a foreign organising midfielder — alongside Thanh Long — a domestic ball-winner — forms a classic pairing: one sets the tempo, the other clears up. That structure can free Quang Hai and Dinh Bac into higher areas of the pitch, where they are most dangerous.

In other words, Cong An Ha Noi do not need fast transitions to create chances. They have enough individual quality to create chances from established possession. The Cong - Viettel, by contrast, need a moment — a tackle, a vertical pass — to convert a defensive shape into a goal.

Everything in football is a transition, including for those who lack the level to understand it. And this is where the two models diverge most sharply as systems.

The Cong - Viettel transition from the bottom up. When the back line holds firm, they exploit the instant after winning the ball to push it forward quickly. This model demands a disciplined block and players who understand their role in every phase. It leaves no room for individuals to break the structure.

Cong An Ha Noi transition from the top down. Individual quality allows them to sustain high pressure and handle the ball in tight spaces. But that model carries a price: when the stars are off form, the system offers few structural fallbacks. A star-gathering club still needs a tactical skeleton for those stars to operate within — it cannot rely purely on moments of brilliance.

Contrarian angle: what the crowd sees and what it misses

The majority will look at Cong An Ha Noi's line-up and conclude they are stronger. Four national-team players in the starting XI is an impressive number in the V.League context. But scouting experience taught me that individual quality and collective quality are two different things. A contract is not a destination — it is only a shard of pottery on the road to a lost city.

People once laughed at me when I said that packing many stars into one dressing room can create problems rather than solve them. They laughed again when I said that selling an academy graduate to buy an established star is often not a step forward. But the social feedback loop is a cruel coach — it never sleeps and never forgives. Cong An Ha Noi, as reigning champions, will be judged on results, not process. Every draw can be read as a small crisis.

There is a structural risk rarely discussed: when a club concentrates most of its wage budget on a small group of star players, the ratio of top wage to average wage rises. That is one of the classic imbalance signals inside a dressing room. It may not explode. But it is always there, waiting.

By contrast, The Cong - Viettel's academy model is dismissed as less glamorous. Yet they hold something money cannot buy overnight: a continuous development pipeline. I do not train players. I excavate what they already were, before the world told them who they had to be. And at The Cong, that tradition of excavation has existed far longer than any single contract.

But here I must argue against myself. An academy model is not automatically superior. It can also become an excuse to rationalise underinvestment. If The Cong - Viettel keep trusting the same core without upgrading, stability curdles into stagnation. What could prove me wrong? If Cong An Ha Noi win convincingly in two consecutive seasons, I will have to revisit my assumption about integration risk. At that point, evidence will beat my argument, and I will accept it.

Takeaway: what to track across the season

The derby between the army club and the public-security club is more than a single fixture. It is a test of a larger question for Vietnamese football: can a league develop sustainably when a handful of clubs hoover up the national-team stars while others try to develop and sell in order to survive?

I will track two things this season. First, the share of academy graduates from The Cong - Viettel appearing in starting line-ups. Second, how Cong An Ha Noi cope when one of their stars is absent through injury. Those two indicators will say more than any league table about the future of domestic football — and about which model can truly bear the weight of a long season.
