ADG Refereeing
Clearer Decisions Under Pressure
High Visibility and Clear Sightlines
Any proposed tiebreaker that restores the contest to real football moments will naturally place referees back in the decision-making process. ADG does not remove pressure from officials, but it gives them a far clearer and more controlled environment in which to apply the Laws of the Game.
This is an important distinction. Penalty shootouts largely remove refereeing judgment from the decisive phase of a match, while extra time often asks referees to make critical decisions amid fatigue, congestion and escalating pressure. ADG sits between those extremes. It keeps referees involved in real football decisions, but places those decisions inside a simpler and more visible structure.
Each ADG contest involves only three active players in open space: an attacker, a defender and a goalkeeper. Consequently, the referee can focus on the contest without the congestion, obstruction and off the ball incidents that complicate open-play decisions.
The goal line assistant referee provides a second fixed angle, assisting the referee with decisions when required and determining whether the ball has fully crossed the line before the 15-second signal. With non-competing players restricted to the unused half of the field, the risk of crowding, confrontation or intimidation is eliminated.
Control Under Pressure
ADG undoubtedly places referees in high-pressure moments, but those moments occur within a structured and predictable format. The phases of play are clearly defined, the number of active players is limited, and each contest begins from a fixed starting position. These conditions make many responsibilities considerably simpler than in open play. Officials are not tracking twenty-two players across a full field. They are judging one contained football action, with clear starting positions, clear termination conditions, and clear consequences for fouls.
The pressure is real, but it is hardly unfamiliar at the highest level of the game. Elite referees already make match-defining decisions in World Cup finals, continental showpieces, and title-deciding league matches. As the legendary tennis player, Billie Jean King famously said, “Pressure is a privilege.” The best officials understand that decisive moments are inseparable from elite sport. They prepare accordingly and ultimately relish the opportunity to make the big calls on the biggest stages.
Refereeing itself has also evolved dramatically since the penalty shootout was introduced in 1970. Modern elite referees are full-time professionals who undergo rigorous physical, technical, and psychological preparation. They study match footage, train for specific scenarios, and face continuous assessment across every aspect of their officiating.
The emergence of professional referee bodies, supported by analysts, fitness coaches, sports scientists, and dedicated performance staff, reflects just how far the profession has come. ADG is well suited to that environment. It creates a repeatable, trainable format where positioning, judgment, and match management remain central, while unnecessary chaos is removed.
Simpler Decisions
One of the key officiating advantages of ADG is that its rule framework reduces ambiguity. Any foul committed by the defender or goalkeeper results in a penalty kick, eliminating the need to determine whether a foul occurred inside or outside the penalty area. Offside is also removed from the equation entirely, since there is only one attacker active at any time.
ADG also addresses one of the most persistent controversies in penalty shootouts: whether the goalkeeper has moved early from the goal line. The issue generated enough controversy for IFAB to modify the sanction in the Laws of the Game. Johan Cruyff, who experienced the NASL 35-yard shootout firsthand, put it plainly. “With penalties you’ve always got problems about whether the goalkeeper moved. You don’t get this with the shootout.” 22 In ADG, a standard penalty occurs only when the attacker has been fouled, and simulations estimate this happens in just 5.7% of contests.
VAR would be used sparingly in ADG because the nature of format strictly limits the number of likely reviewable incidents. With fouls occurring in fewer than 6% of contests, a standard ten-contest ADG sequence would average only 0.6 fouls. Even using a conservative assumption that 75% of those fouls required VAR review, this would produce fewer than one VAR per ADG tiebreaker.
This matters because VAR remains unpopular when it slows the game or appears to re-referee marginal contact. In ADG that concern is reduced by the low foul rate and by the structure of the contest itself. The 15-second time limit gives each contest a defined endpoint so any VAR review occurs during a natural stoppage. That combination keeps VAR available at the discretion of the referee without it becoming a constant feature of ADG.
Fewer players, better sightlines, a simpler set of consequences, and clearly defined laws mean that officials can approach ADG with confidence and get the big calls right.

| Refereeing Implications | Normal Play | ADG |
|---|---|---|
Increased visibility | No | Yes |
Referee always close to the play | No | Yes |
Mass confrontation avoided | No | Yes |
Offside not applicable | No | Yes |
Foul inside/outside Penalty Area not applicable | No | Yes |
Reduce goalkeeper off goal line controversy | No | Yes |
VAR less disruptive | No | Yes |
Officiating Advantages: ADG reduces several common sources of officiating pressure, including congestion, offside, penalty-area boundary disputes, goalkeeper movement controversies and disruptive VAR delays.
Assistant Referee Duties
ADG gives each assistant referee a clearly defined role. The centre circle assistant referee organises and supervises the non-competing players in the disused half of the field, maintaining player order and ensuring the correct players compete in the correct contests.
The goal-line assistant referee is positioned on the goal line and assists the referee with decisions close to goal, including goalkeeper actions and whether the ball has fully crossed the line before the 15-second signal expires. This role resembles how UEFA previously deployed their additional assistant referees.
In major tournaments, goal-line technology could also be enhanced to confirm whether the ball has fully crossed the line before time expires. Linked to the stadium scoreboard, the live 15-second countdown would also be visible to supporters, adding a palpable layer of suspense and excitement.
The referee keeps the official ADG scorecard, while the centre circle assistant referee maintains a parallel record of player order, shirt numbers and the score. Together, the colour-coded scorecard and the physical player lines within the centre circle operate as a single organisational system, giving the officiating team a clear and immediate means of verifying identity, sequence and the scoreline throughout.

Why Fouls Are Rare
The estimated foul rate of fewer than 6% may seem low, but it reflects the incentives built into ADG. Unlike open play, defenders have little reason to attempt risky tackles because any foul by the defender or goalkeeper results in a penalty kick. With penalties converting at 75%, a mistimed challenge is usually far more costly than allowing the attacker to continue under ADG’s lower scoring conditions.
As a result, defenders are more likely to contain rather than lunge. They can track the attacker, delay the shot, narrow the angle, force the attacker wide or wait for a mistake. This defensive behaviour reduces the likelihood of careless or reckless fouls while still preserving genuine football pressure.
Visibility also shapes behaviour. In open play, some fouls occur in congestion, from blind-side angles or away from the referee’s immediate focus. ADG removes much of that ambiguity. Because every contest is isolated and watched by the referee, assistants, VAR and the entire stadium, defenders have less opportunity and less incentive to disguise contact or take a speculative risk.
ADG’s Monte Carlo simulations support this pattern. Even under aggressive defensive assumptions, fouls usually occur only when the attacker is about to shoot or has clearly beaten the defender. At professional level, where players are highly tactical and acutely aware of the cost of conceding a penalty, that containment approach should be even more pronounced.
DOGSO in ADG
Because every ADG contest is an inherent goal-scoring opportunity, fouls by the defender or goalkeeper are assessed through the DOGSO framework. However, that framework must be adjusted because the attacker’s opportunity is always restored through a penalty kick.
To avoid excessive sanctions, careless fouls by the defender or goalkeeper are not automatically cautioned. The penalty kick is the primary deterrent and restores the goal-scoring opportunity lost through the offence.
Stronger sanctions still apply where the offence is unfair or dangerous. Holding, pulling, pushing, or any offence with no attempt to play or challenge for the ball receives a yellow card rather than the normal red. Reckless challenges remain cautionable offences, and excessive force remains a sending-off offence.
Handball sanctions remain strict just as they are in open play. Non-deliberate handball is punished with a yellow card, while deliberate handball continues to be a red-card offence.
In summary, ADG modifies only the sanctions that would otherwise become disproportionate because every contest is an obvious goal-scoring opportunity. Careless fouls are not carded, and holding, pulling, pushing or non-genuine challenges are reduced from red to yellow. Reckless fouls, excessive force and handball offences remain sanctioned in the same way as standard DOGSO incidents that occur within the penalty area.
| Offence | Standard DOGSO Sanction * | ADG Sanction |
|---|---|---|
Careless foul | None | |
Reckless foul | ||
Holding, pulling or pushing, or no attempt to play the ball | ||
Excessive force foul | ||
Non-deliberate Handball | ||
Deliberate Handball |
* Denying an Obvious Goal-Scoring Opportunity within Penalty Area
DOGSO Sanctions: Because every defender or goalkeeper foul in ADG results in a penalty kick, the goal-scoring opportunity is restored. This allows sanctions to remain proportionate while preserving strong deterrence against unfair or dangerous play.
