Jay Idzes Out, Thom Haye Carries the Midfield: Indonesia vs Singapore and the Gaps That Don't Show on Paper

I rewatched the tape of Indonesia's 1-1 draw with Singapore from just over a month ago and paused at the 78th minute. The ball was at the feet of a Singapore midfielder, and behind him, Song Ui-young had already started running. Not a sprint. It was the kind of run I taught myself to count during the football-less summer of 2026: a run into the space a defense had just exposed after its midfield was dragged out of shape. On first viewing, I missed it. By the fourth, I realized Indonesia had lost Jay Idzes at that moment. And their problem at Gelora Bung Karno is not scoring, but preventing that gap from being exploited a second time.

Context: A Group Opener Carrying Two Stories Out of Sync

The opening group-stage match of the Southeast Asian regional competition between Indonesia and Singapore takes place at Gelora Bung Karno, with a capacity of nearly 80,000. According to multiple sources I cross-checked, hosts Indonesia enter with a squad heavily populated by players based in Europe, while Singapore arrive as a tightly organized collective under 36-year-old head coach Gavin Lee.

Singapore's predicted lineup leans mostly on domestic and regional players: Hariss Harun, the captain and spiritual anchor; Ilhan Fandi and Shawal Anuar as forward outlets; Kyoga Nakamura and Nur Shahiran likely tasked with controlling the middle third. On Indonesia's side, John Herdman has called up his 24 best players, with Thom Haye, Kevin Diks, Justin Hubner and Jordi Amat among the more notable names.

The most striking detail is not in the starting XI but in the injury column. Jay Idzes, described as an "expensive" center-back, is absent for fitness reasons. Indonesia's coaching staff reportedly considers the absence "not too influential." That is a line I have heard many times in 14 years of following transfers and international football, and it always makes me pay more attention rather than less.

One more signal worth putting on the table: Indonesia's players have just returned from various tournaments with uneven fitness. In an opening match played outside the official FIFA window, the release of players by parent clubs is voluntary, not mandatory, and that is something that requires verification, not assumption.

Core Tactics: Thom Haye Is the Axis, But an Axis Needs Support

Indonesia's build-up is likely to flow through Thom Haye. He is the tempo-controller type, launching attacks with through-balls that carry both spin and quick decision-making. Based on the data I have compiled, every structured Indonesian progression through midfield begins with the ball reaching his feet before it is distributed wide or into the inside channels.

The weakness of this model is obvious against Singapore: if Kyoga Nakamura or Nur Shahiran is assigned to man-mark him tightly, or if Gavin Lee sets up zone-based pressing to cut the diagonal passes from Haye to the flanks, Indonesia will need a secondary creative source. Kevin Diks and Justin Hubner can step up and hit long passes, but they are center-backs, not creative midfielders.

The compatibility index is not on paper; it lives in how players run. With a squad largely born and trained in Europe, Indonesia hold an advantage in individual quality but also face a different problem: syncing off-ball movement. Players coming from different club systems need time to align their movement rhythms, especially in transition moments and when receiving from the second line.

The key point: if Singapore can smother Haye in the final 30 meters, Indonesia will have to switch to long balls toward the forwards, and Singapore's defensive structure — described as "difficult to play against" — will then hold a positional advantage.

Song Ui-young and the Jay Idzes Problem

If Indonesia have Thom Haye, Singapore have Song Ui-young. Both can shape a match, but in opposite ways. Haye distributes from deep. Song Ui-young runs into the box from behind. He is not a ball-carrier, but a reader of space who arrives at the right moment.

With Jay Idzes absent, Indonesia's central defense will likely be reorganized around Kevin Diks, Justin Hubner or Jordi Amat. All are experienced, but none matches Idzes' running profile and depth-covering ability. Tracking Song Ui-young's late arrivals requires the holding midfielder to drop at the right moment and the back line to maintain line spacing — both extremely difficult when the squad has just come through multiple matches at different intensities.

I don't count keepy-uppies; I count the moments a player is suffocated by the system. Song Ui-young is the clearest example of a player whose value basic metrics cannot measure. His goals and assists may not stand out, but his appearances in the "false forward" zone inside the box are the number worth tracking. And when an opponent loses a center-back who can convert defense into attack, those runs find room.

The Blind Spot in the Official Narrative: An Unverified 1-0

This is where I want to be blunt. A 1-0 Indonesia win appears in pre-match reports as if it were established fact, but I cannot find in any source a single specific metric to support it: no xG, no PPDA, no possession share, no set-piece data. A prediction with no process data behind it is just an opinion delivered in a confident tone. That does not mean the prediction is wrong — it means it cannot be treated as a conclusion, only as a hypothesis.

Alongside that, one detail made me pause: the competition is labeled "FIFA ASEAN Cup 2026" in some reports. Southeast Asia's regional tournament is normally organized under the ASEAN Football Federation (AFF), not FIFA directly. If the name is wrong, that is not a small administrative error but a signal about source-verification quality. Misreading names taught me: look at the contract, not the mouth. And when a report has no byline, no newsroom, no timestamp for cross-checking, I treat it as a probabilistic signal, not fact.

There is one more point worth noting about home advantage. Playing at Gelora Bung Karno is always a major boost for Indonesia, in terms of crowd pressure and matchday revenue. But in an opener, that advantage can flip if the hosts do not score early. Nervous energy from the stands rebounds on the home players, especially against a well-organized opponent that knows how to slow the tempo and manage the clock. If the first 60 minutes stay 0-0, both a 1-0 win and a draw have equal grounding.

The psychological backdrop also needs repeating: Singapore stopped Indonesia at the group stage with a 1-1 draw just over a month ago. That is a single match, too small a sample to conclude anything about relative strength, but enough to establish that Singapore is not an opponent that can be automatically written off.

What I Want You to Carry Into This Match

Singapore under Gavin Lee does not build around a star; it builds around structure. Hariss Harun provides stability at the back and captaincy presence, but Singapore's greatest asset lies in maintaining team distance and exploiting second balls. Indonesia has superior individual quality, but individual quality only converts into goals when there is rhythm and space. This match will be decided in transitions and set pieces, not in long passing sequences.

If Indonesia score inside the first 20 minutes, the script may open up and they could win by more. If not, Singapore will drop the block lower, pull Haye away from receiving positions, and wait for Song Ui-young's second-line bursts. That is the next domino — and it lives in how Singapore's players move, not in a pre-match scoreline.

What I believe only begins when money changes hands — or when the ball hits the net.
