Naturalization Is Not a Shortcut: Rereading the Indonesia–Vietnam Equation Through European Club Tiers

Naturalization Is Not a Shortcut: Rereading the Indonesia–Vietnam Equation Through European Club Tiers

On the evening of November 15, 2026, I sat on the second floor of a coffee shop on Lach Tray Street in Hai Phong, watching a big screen showing Indonesia against Japan in the third round of AFC qualification for the 2026 World Cup. The hosts fielded a lineup in which more than half the players were naturalized: goalkeeper Maarten Paes, centre-backs Jay Idzes and Mees Hilgers, left-back Calvin Verdonk, midfielder Thom Haye.

Four goals conceded, the opening one an own goal. Japan never faced meaningful difficulty.

What stayed with me was not the score. A group of young people at the next table told each other: "See, naturalization is the same either way." I have heard that sentence at least a few dozen times over three years, each time from a different person, but always from the same reading error.

I took the notebook out of my backpack. That page had been written back in September, when an agent in Jakarta called me about a fresh batch of naturalization files that PSSI was fast-tracking. Outsiders look at the contract. I look at the dinner before the signature.

Then early in 2026, a speech by former Vietnam Football Federation vice president Duong Vu Lam was picked up by Indonesian media, framed sharply: Indonesia's naturalized players play only at mid-tier and lower-tier European clubs, nothing compared to the stars of Japan, South Korea, Iran or Australia. He also invoked the China precedent as a warning and argued Vietnamese football should treat youth development as its foundation rather than making naturalization its main strength.

I noted one line immediately: dates need verification. There are figures and dates in this story whose origins I have not confirmed, and I will say so plainly later.

Rumours are not wrong — they simply arrive earlier than the truth. But a speech is not a rumour. A speech is an argument, and an argument must withstand the pressure of data.

Context: A Race Nobody Declared

Over the past three years, Southeast Asia has witnessed a race no federation has formally named. Indonesia moved first and fastest. PSSI built a dedicated pipeline to identify players of Indonesian descent in the Netherlands, Belgium, Italy and the United States, process their legal files under FIFA Articles 5–8 on international eligibility, and insert them into the national team as quickly as possible.

That list is not small: Maarten Paes, Jay Idzes, Mees Hilgers, Calvin Verdonk, Thom Haye, Shayne Pattynama, Ivar Jenner, Justin Hubner, Rafael Struick, Ragnar Oratmangoen, Eliano Reijnders, Kevin Diks, Ole Romeny. Every name is a file, a phone call, a verification of a grandparent's birth certificate, a flight.

Vietnam, over the same stretch, held a more cautious public line. Reality was less tidy. Nguyen Xuan Son — born Rafaelson — has worn the Vietnam shirt since late 2026 and scored on his debut. He is a naturalized player, in the full sense.

The paradox sits here: a speech opposing naturalization as a primary strength was delivered while the very national team the speaker once helped administer had already leaned on a naturalized striker as its attacking anchor.

I do not write this to score a point. I write it because it is the single most important detail in the whole story, and most regional coverage skips it.

The competitive context matters. Japan, South Korea, Iran and Australia occupy Asia's first tier, with players regularly starting in the Premier League, Bundesliga, Serie A, Ligue 1 and La Liga. Indonesia and Vietnam sit in the second tier, alongside Iraq, Saudi Arabia at the margin, and Thailand. Within one tier, the gap between two teams is often a handful of points and a few moments.

At that distance, every time one side upgrades its squad, the other feels pressure. The Southeast Asian naturalization race is therefore not a philosophical story. It is a rankings story.

Analysis: Three Errors Inside One Argument

The argument has three layers. Layer one: Indonesia's naturalized players play at mid-tier and lower-tier European clubs. Layer two: Japan, South Korea, Iran and Australia have players at top European clubs. Layer three: therefore, naturalization cannot lift a team to continental level.

Layer one has a factual basis. Check the evidence.

Jay Idzes plays for Venezia. Mees Hilgers plays for Twente. Calvin Verdonk plays for NEC Nijmegen. Thom Haye has played for Heerenveen. Shayne Pattynama plays for Viking in Norway. Ivar Jenner belongs to Jong Utrecht. Eliano Reijnders plays for PEC Zwolle. That is the Eredivisie, the Dutch top flight — a good league, the first division of a nation with real football tradition, but not one of Europe's top five leagues.

Compare Japan: Takefusa Kubo at Real Sociedad, Kaoru Mitoma at Brighton, Wataru Endo formerly at Liverpool. South Korea: Kim Min-jae at Bayern Munich, Son Heung-min at Tottenham, Lee Kang-in at Paris Saint-Germain. Iran: Mehdi Taremi at Inter Milan. Australia: a spread of players across the Premier League and Championship.

At the level of facts, layer one holds. At the level of conclusion, it collapses.

The first reason is proxy error. Club tier is a weak indicator of individual quality. A bench player at an elite club is not automatically better than a starter making 34 appearances at a mid-tier club. Position, minutes, role in the system, and positional scarcity all matter. Jay Idzes starts in Serie A for Venezia. A Serie A starter, even at a club fighting relegation, is not a "mid-tier and lower" player.

The second reason is comparison error. You cannot take an entire cohort of one nation's naturalized players and set it against the most elite individuals of four top Asian football nations. Japan has hundreds of players in Europe; you only recall the most famous. Indonesia has a dozen or so naturalized players; you judge the whole group through each individual. That is apples to oranges, and it makes the conclusion look stronger than it is.

The third reason is a category jump. Moving from "mid-tier club" to "no contribution to the national team" is an unproven leap. Contribution to a national team depends on role in the tactical system, chemistry with teammates, and the ability to perform at international intensity. None of that appears on a transfer ledger.

At this age, I have learned that real value does not sit on the fee. Nor does it sit on the name of the league a player currently plays in.

Data Must Be Read Together, Not in Isolation

Based on my experience tracking matches in the third round of 2026 World Cup qualifying, three indicators matter more than club tier.

First, club minutes. A player logging 2,400 league minutes in the Eredivisie carries a more stable fitness and rhythm base than one logging 600 scattered minutes in a stronger league. This is public, free data, and almost nobody uses it in these arguments.

Second, playing position. Asian football suffers a severe shortage along the spine: commanding centre-backs, holding midfielders who can switch play, target strikers who hold the ball up. Naturalization in those positions carries far higher marginal value than naturalizing a winger. Indonesia has naturalized precisely into scarce positions: centre-back, goalkeeper, central midfield, striker.

Third, squad depth. A national team with 11 good players and 12 weak ones collapses when two injuries hit. A team with 20 adequate players survives an 18-month qualifying campaign. Naturalization, at bottom, is a depth strategy, not a star-making strategy.

I want to be clear on this point because it is usually inverted. Naturalization rarely produces a Son Heung-min. It produces ten players you do not have to worry about. The value lives there.

And this is where the China precedent becomes more interesting than it first appears.

China naturalized a batch of Brazilian and English players for the 2026 World Cup qualifying campaign: Elkeson, Alan Carvalho, Aloisio, Tyias Browning, Nico Yennaris, Fernandinho. The result: China finished fifth in Group B of the third round and did not reach the 2026 World Cup. The argument runs: see, naturalization did not help.

Look at the detail and the picture changes. China naturalized late, after its domestic core had aged, and it naturalized into attacking positions while the defence remained the problem. That was an under-designed naturalization programme, not a failure of the idea of naturalization.

One failure of one case is not evidence of a rule. It is one case.

Opportunity Cost: The Number Nobody Publishes

Here I must be honest about my own limits.

The argument that money spent on naturalization is money not spent on youth development is reasonable in principle. It needs figures. Which federation spends how much on diaspora scouting, legal processing, flights, sports lawyers? Nobody publishes this. I have asked three federation staff across two countries over two years, and all three laughed.

Without numbers, the opportunity-cost argument is a moral argument, not an economic one.

But the other side deserves saying too. Naturalization carries commercial value almost nobody counts. When a national team has players active in Europe, broadcast rights prices rise, audiences grow, matches become more sellable. That money flows back to the federation, and a portion flows back to grassroots football.

A winning national team also means more children signing up at academies. Academies are not fed by inspiration alone, but inspiration is a necessary condition for an academy to exist.

I do not believe in luck; I believe in reading people correctly. And reading people correctly here means reading both sides of the scale, not only the side that suits the argument you picked in advance.

The Blind Spot: The Official Story Looks Better Than the Truth

The official story in Southeast Asia is told in two versions, and both have problems.

Version one: naturalization is a shortcut, a back door onto the Asian stage, an assault on the purity of domestic football. This version ignores the fact that Indonesia's naturalized players are Indonesian by descent, by nationality, and by the legal standard FIFA sets. They are not mercenaries. They are people coming home to a home they never lived in.

Version two: naturalization is an inevitable upgrade, and simply adding more European-born players makes you stronger automatically. This version ignores the fact that a national team is a social system, not a feature list. Eleven good players do not automatically make a good team. The proof is the 4-0 I watched on November 15: Indonesia had the strongest individual squad in its history, and Japan flattened it with a structure twenty years in the building.

The real blind spot sits between those two versions, and it has a name: coaching and organisational capacity.

Without a system, without a curriculum, without a tactical foundation running from U15 to the senior side, naturalization is pouring water into a leaking bucket. The genuine opportunity cost is not youth development money. It is staff capability.

And that is the thing no federation wants to say out loud.

An empty stand does not mean nobody is listening. In this case, the listeners are not in the stand. They are in coaching meetings, in licence courses, in training workshops cancelled for lack of budget.

The Race Vietnam Is Also Running

One important detail rarely gets mentioned: Vietnam is on the same road.

Nguyen Xuan Son debuted for Vietnam at the 2026 ASEAN Cup and immediately became a key attacking factor. That is a signed document, not a rumour. I verified this through official reports and through matches I followed directly.

So the point is not whether Vietnam should naturalize. The point is: Vietnam is naturalizing, and the right question is what design it is naturalizing under.

Designed naturalization is built inside a plan with a position, an age profile, a minutes target, an integration pathway, and someone accountable for delivery. Undesigned naturalization is reactive, and reactive usually arrives after your rival has finished.

I have written three times about naturalization cases in the region, and every time I hit the same response: "But they are not Vietnamese."

I understand that response. I am here, in Hai Phong, and I know what a stand feels like when the home team walks out. Identity is real. But identity is not fixed. It is built, match by match, season by season, by the people wearing the shirt and the people sitting in the rain to watch.

At 25, I am not old enough to claim I know everything. But I have been in this trade long enough to recognise one thing: every rumour is a door; I only write about doors left ajar. And Southeast Asia's naturalization door is open, whether or not someone wants it shut.

What Needs Verifying, and What Should Be Believed

I have an obligation to state the reliability of the facts in this story, because my trade is cross-checking sources.

I have not verified the exact date of the original speech. Some reproductions carry a date inconsistent with the current qualifying cycle. I treat every temporal reference in this story as data to be verified, not settled fact.

I believe the substance of the statement was conveyed accurately: Indonesia's naturalized players mostly play at mid-tier European clubs; the four leading Asian football nations have representatives at bigger clubs; the China precedent exists; and the youth-first position is a genuine policy view.

I do not believe the exaggeration. Framing it as "nothing compared to Japan" is a slogan, not an analytical conclusion. And Indonesian outlets handling it as a needle aimed at Indonesia made the story run hotter than its evidence permits.

A lesson from Mbappe I always carry: watching speed is fine, watching direction of movement is better. Here, the speed is the headline. The direction of movement is the question of football organisational capability, the thing that decides whether naturalization succeeds or becomes a farce.

What Comes Next

From my experience tracking player movement in the region, I see three dominoes standing.

First, Indonesia will keep naturalizing, but will shift focus toward younger positions and toward retention rather than emergency call-ups. Maarten Paes and Jay Idzes are the foundation; those who follow will be younger.

Second, Vietnam will have to pick one path publicly. Holding a youth-development line on paper while fielding naturalized players on grass is an unstable position. It creates an internal debate that media will mine over the next 12 months.

Third, and this is the biggest domino: if two or more Southeast Asian nations naturalize at scale, naturalization's relative advantage disappears. When everyone upgrades, nobody upgrades. The reward returns to where it always lived: coaching quality, league quality, and the training hours of a twelve-year-old.

One thing I am certain of after all these years reading the transfer market. A naturalized player scoring in the 90th minute will hear the stand sing his name. A football nation with the right coaching system will produce a generation that scores in the 90th minute for twenty consecutive years.

Writing for the forgotten is reminding them I never stopped watching. The forgotten people in this debate are not the naturalized players. They are the coaches of provincial U17 sides, who will never appear in any article at all. But if Southeast Asia's naturalization story ends well, it will start where that coach stands.
