Olaha Manh Duc and Coach Kim Sang Sik's Attacking Puzzle

Thien Truong Stadium, the closing minutes of Nam Dinh's match against the visitors. The ball broke loose off a defender after a low cross was cleared. Olaha Manh Duc collected it at the edge of the box and struck it low. The keeper dived late. It was the kind of goal scouts call a poacher's goal – not a constructed move, but the reward for standing in the right place when chaos erupted.

That moment did more than secure three points for the team from the South. It added the latest piece to the attacking picture Coach Kim Sang Sik is waiting on before the Vietnam national team gathers. After four rounds of V.League 1, four forwards have scored: Nguyen Tien Linh and Le Phat with two each, Olaha and Nguyen Tuan Hai with one apiece. Six goals across four rounds, spread over four different names – a telling number.

But to read that number correctly, it has to be placed in context. This is a period in which Vietnam are missing Nguyen Xuan Son long-term. Kim Sang Sik's problem is not finding a goal. It is finding an attacking structure that can function without a reference No.9. And among the four names in form, each represents a different answer.

Four names, four striker profiles

Nguyen Tien Linh is the classic centre-forward. His aerial ability is an asset verified across multiple seasons, and in V.League, few domestic defenders can contest a header with him inside the box. Two goals in four rounds, half a goal per match, is stable club-level output. What matters more than the number is how he scores: mostly from dead balls, corners and crosses from the flanks.

Nguyen Tuan Hai is a different profile entirely. He is not a player who waits for the ball in the box. He creates his own space with runs that break the line, bursts from the second line of attack, and the ability to finish from outside the area. Tuan Hai's goals tend to arrive in situations where the opposing defence has already been stretched, and he is the one who exploits the gap.

Le Phat offers the most interesting selection story. Two goals in four rounds places him in a position no other forward holds: he is scoring consistently, while Nguyen Gia Hung and Nguyen Viet Cuong have none. At international level, form is always a difficult argument to dismiss. A player scoring regularly in the domestic league creates selection pressure no coach can entirely ignore.

And then there is Olaha Manh Duc – the most interesting name of all.

Olaha: a system piece, not just a goal tally

What sets Olaha apart is not his goal count. One in V.League, one in the Shopee Cup – that is not more impressive than Tien Linh or Le Phat. What matters is his profile: a forward who can play multiple positions across the front line and who can strike from distance.

With Vietnam missing Xuan Son long-term, that is a profile with far higher systemic value than it appears.

A versatile forward who can play wide frees Kim Sang Sik from the one-for-one replacement problem. With Xuan Son fit, the team operated around a fixed reference No.9 – a player who held the ball, acted as a wall and dragged defenders. Losing him does not mean finding a clone, which is close to impossible at this level, but finding a different structure that works. Olaha, able to play both centrally and wide, gives Kim Sang Sik more flexibility in personnel without tearing up the whole system.

But this is where clarity is needed.

The Olaha goal I described at the start – a cleared cross, a loose ball, a close-range finish – is a poacher's goal. That is the skill of standing in the right place in chaos, not the skill of creating in combination. It is a low-repeatability goal type at elite level, and more importantly, it translates poorly against deep, compact, well-organised defences.

And that is precisely the opponent type Vietnam face most in ASEAN competition.

Regional teams facing Vietnam rarely push high. They drop off, build two defensive blocks, seal the space between defence and midfield, and concede possession. Against such a block, a forward who is only good at standing in the right place gets isolated. The ball does not reach where he stands, and even when it does, the space to shoot has been closed.

That is why Olaha's long-range shooting is worth more than it looks. Against a deep block, shots from distance are one of the few remaining ways to break a game open. But it must be said plainly: goals from outside the box are also a low-repeatability event class. A national attacking plan cannot be built on the expectation that a forward will keep scoring from 25 metres.

The most viable structure

If one forward pairing had to be chosen for Vietnam in the coming window, the tactically soundest option is Tien Linh highest, Tuan Hai dropping deeper as a second striker or shadow forward.

The reasoning is concrete. Tien Linh's aerial ability and Tuan Hai's instinct for arriving in the box are the two qualities the current context demands. One holds the central position, draws defenders and finishes crosses. The other moves into the space defenders leave when they are pulled toward Tien Linh, and finishes from the second line.

This is a crossing, second-ball attacking structure – not a possession structure. With the available personnel, it is the most realistic choice. Possession football at international level requires a midfield capable of circulating the ball under high pressure, and that is a separate story, outside what the attack currently provides.

In this shape, Olaha serves as the direct back-up for Tien Linh – the only one in the group with an equivalent physical profile to replace the centre-forward role when needed. His ability to play wide is the expansion option, allowing Kim Sang Sik to change structure mid-match without a substitution.

The biggest blind spot

The goal numbers cannot capture one risk: the integration cost.

A newly naturalised forward joining a FIFA window of roughly ten days, with no camp history, no familiarity with team-mates, no familiarity with the system, no familiarity with how each midfielder delivers the ball. Club form does not convert automatically into international output. This is the gap many forwards with strong club form have failed to cross.

For Olaha, the gap is larger than usual, because he has never been through a national-team camp. Ten days is far too short to build the understanding international football demands.

This does not mean he should not be called up. It means expectations must be placed correctly: Olaha is a medium-term option, not an immediate solution for the coming window.

There is another blind spot, in how these numbers are read. Six goals in four rounds is a small sample. Four rounds is not enough to establish form, and certainly not enough to conclude anything about tactical trends. Over four rounds, one forward can score twice through two fortunate situations, while another scores none despite playing better. Goals are the most visible metric, but not the most reliable.

Notably, across all available data, there is not a single metric on shot volume, chance quality or key passes. We are reading football through goals, while goals are the tip of the iceberg.

What needs verification

Three rounds remain before the national team gathers. Those three rounds will answer several questions far more specific than counting goals.

Will Olaha keep scoring in other ways – from combination play, from assists, from situations that are not loose balls? If so, his profile is worth far more than one poacher's goal.

Will Tien Linh hold the No.9 position, or will teams begin man-marking him and cutting the aerial supply? How he responds to being tightly marked will say much about his capacity to lead the line internationally.

And Tuan Hai, in a second-striker role at club level, can he sustain his ability to arrive in the box at the right moment?

Three rounds, three questions. That is enough time to separate a forward in form from a forward with quality. For Kim Sang Sik, the difference between those two things is the difference between an attack that functions and an attack that only looks good on paper.
