Indonesia's Four Attacking Options at the 2026 ASEAN Cup: Vickery, Romeny, Baker and the Data Gap Herdman Has Not Closed

Last season, Luke Vickery scored 5 goals and added 1 assist in 24 A-League Men matches. In the AFC Champions League Two, the 20-year-old Macarthur FC winger scored 2 and assisted 2 in just 6 games. Converted to a per-90 rate, the gap between the two competitions is nearly threefold. For someone who reads numbers for a living, that is the kind of divergence that forces you to stop.

I sat in Hamburg, cross-checking statistical tables from leagues German television barely broadcasts. A young player with no senior international minutes somehow posts a higher rate in continental cup football than in his domestic league. There are two ways to read it. First, he suits open games where opponents leave space behind their back line. Second, six matches is too small a sample to conclude anything. I choose both readings. And that is exactly why Indonesia's attacking puzzle at the 2026 FIFA ASEAN Cup is more interesting than the "promising" label regional media have stuck on it.

Some numbers only tell the truth at midnight. They have only just started speaking.

Four profiles, four measures that do not share a unit

The attacking group coach John Herdman currently has at his disposal features four names most often mentioned: Luke Vickery, Ole Romeny, Mitchell Baker and Ragnar Oratmangoen. Four profiles, four competition levels, four data samples that do not share a common unit. That is the first thing worth stating clearly, because any hasty comparison between them is a comparison across incompatible denominators.

Vickery plays for Macarthur FC in the A-League Men. His profile is that of a wide-running winger: pace, stretching opposing back lines. Five goals and one assist in 24 matches sounds modest, but that is a league with a markedly higher tempo and more space than Southeast Asian competitions. In the AFC Champions League Two, where the opposition quality is more even and the pressure higher, he scored 2 and assisted 2 in 6 games. Look only at the second figure and you will over-expect. Look only at the first and you will undervalue him.

Romeny is different by nature. He plays in the Eredivisie for Fortuna Sittard, already knows the national-team system, and can operate centrally or drift wide. The drop-deep, link-and-release forward — what modern football calls a linking number nine — carries particular value for a national team that regularly faces compact Southeast Asian defences. Someone who knows how to drop and drag a centre-back out of position is more useful than someone who simply waits for the ball inside the box.

Baker is the third archetype: a penalty-box finisher. Four goals at the 2026 AFF Cup, including a hat-trick on debut, plus 9 goal contributions in 8 games for the club side Georgetown. I have not been able to verify Georgetown's competition level, so I will set that number aside for now. But a debut hat-trick I know well: one explosive match can distort an entire short-tournament figure.

Oratmangoen appears on the four-strong shortlist but comes with almost no tactical description attached. Based on my experience following Indonesia's national-team matches, that is usually the signature of the most experienced fallback option — the one undervalued simply because it is not pretty.

Profile variety and the question no spreadsheet has answered

The most notable thing is not any individual, but the structure. Herdman has three almost non-overlapping striker archetypes: a wide runner, a linker, a box finisher. For a short tournament like the ASEAN Cup, with a congested schedule and constantly changing opponents, profile variety is a bigger tactical asset than any individual. You can play directly against a high defensive line, then switch to second balls against a deep block, without changing the entire system.

That tactical pattern is not new. It is standard in international football: wing pace plus a striker who drops. What is missing is evidence at national-team level.

Here I have to say plainly what the original commentary did not. No match-level data was provided: no xG, no chances created, no pressing metrics, no starting XI, no formation. Phrases like "opening space for other strikers" or "linking midfield to attack" describe an idea, not proof of execution. They may be correct. They have not been demonstrated.

Stand far enough back and every heatmap becomes a painting. But this painting currently has only a frame, not the layers of match data.

More concretely, three gaps prevent me from offering a firm verdict. First, we do not know which shape Herdman will use — a front two, a front three, or a 4-2-3-1 with rotating attackers. Second, we do not know how many minutes Vickery and Baker have played alongside each other, and the chemistry between a wide runner and a box finisher does not emerge from reputation alone. Third, there is no data on whether the club numbers were produced against strong or weak opposition.

The most plausible configuration, if one must guess, is Vickery hugging the touchline, Romeny operating centrally as a free false nine, and Baker as the highest penalty-box threat. But that is inference from player profiles, not from match data. And a model built on profile inference deserves only medium confidence.

Where the model stays silent

This is the part I want to spend the most time on, because it is where mistakes are easiest to make.

Probability is not for believing. It is for sleeping with. I have written that line many times, and it holds most true in cases like this: when the sample is small, when competition levels are inconsistent, and when public expectation runs faster than the evidence.

Look at how the numbers actually behave. Baker's four goals at the 2026 AFF Cup sound impressive. But if one of those four came inside a single hat-trick, the rest of his tournament amounts to one goal. One hot match can turn an average player into a front-page name. Similarly, Vickery's continental rate is roughly triple his domestic rate, but the sample is six matches. Six matches cannot distinguish between "suited to cup football" and "lucky across six matches".

There is another trap few mention: the correlation between having several varied attacking options and scoring many goals in a short tournament is close to zero. Profile variety is a necessary condition for tactical flexibility, not a direct cause of goals. Goals come from the quality of the final action, from creating clear chances, from converting xG into goals. None of those three live in a player profile.

Then there is public pressure, which no spreadsheet ever captures. Vickery is being called one of the most anticipated names in the squad, despite having no minutes at senior international level. That is a high expectation band. If he does not score early, the same pen praising him today will be first to write about the fade. For Herdman, the pressure sits at a medium level: if he underuses Vickery, or the player performs below expectation, questions about selection will surface right after the opening match.

People look at the spreadsheet. I see the breathing. And a young national team's breathing is rarely steady in the first twenty minutes of a major tournament.

One more detail gets overlooked: new attacking combinations are very likely still in a gelling phase. International football offers nowhere near club-level training time. A pacy winger against an organised deep block will stall if no midfielder advances to occupy the space behind him. This is the classic tactical blind spot of Southeast Asian sides: good wide runners, but nobody arriving in the box at the right moment.

Signals for the next cycle

If I had to pick one metric to track for Indonesia at the 2026 FIFA ASEAN Cup, I would not pick Vickery's or Baker's goal tally. I would pick the number of passes into the final third delivered by the midfield line. A varied attack only has value when the ball reaches those players in the right position, at the right rhythm.

The second thing I want to track is Oratmangoen's minutes. If the least-described name on the shortlist turns out to be the man sent on in decisive moments, then Herdman's real priority order differs from the one printed in the newspapers.

And the third, hardest to measure: whether Vickery is given the ball in the positions he used to get in the AFC Champions League Two, or squeezed into a narrower role inside the national-team system. The difference between those two things may be the whole story of this tournament.

Indonesia have a young, varied and genuinely interesting attacking group. But between "interesting" and "effective" lies a gap only match data can close. After this tournament, we will know whether the "promising" label was a forecast, or just a comfortable way of pleasing the fans.
