Refereeing decisions are among the most closely examined moments in modern football. A penalty can change the direction of a match, a red card can alter the balance between two teams and a disallowed goal can become the defining talking point long after the final whistle. Few areas of the game generate as much debate as officiating, particularly since the introduction of VAR.
**Former Premier League referee Dermot Gallagher has spent years examining those difficult moments, offering explanations based on the laws of the game and the perspective of an experienced match official. His Ref Watch analysis has regularly focused on penalties, handball incidents, red cards, offside decisions and VAR interventions. Recent Sky Sports coverage has continued that tradition, including analysis of a controversial Erling Haaland goal in the Manchester derby. **
Why Refereeing Decisions Attract So Much Attention
Football is a sport in which a single decision can have enormous consequences. Unlike many other sports, scoring opportunities are relatively limited, meaning an incident inside the penalty area can have a major influence on the final result.
A referee may have only a fraction of a second to decide whether a challenge is legal, whether contact warrants a penalty or whether a player has committed an offence serious enough for a sending-off. Television viewers, meanwhile, can watch an incident repeatedly from several different angles.
This difference in perspective is one of the reasons refereeing decisions are so difficult to evaluate. A decision that appears obvious from a replay may have been far more difficult for the referee to interpret in real time. Gallagher’s analysis often highlights this distinction, explaining the information available to officials at the moment a decision is made.
Dermot Gallagher’s Refereeing Perspective
Gallagher’s experience as a former Premier League referee gives his analysis a particular focus. Rather than simply discussing whether supporters agree with a decision, he examines the relevant laws and the factors an official is expected to consider.
**His assessments have covered some of the most controversial incidents in English football. In one earlier Ref Watch analysis, for example, Gallagher examined penalty claims, red-card situations and offside decisions while explaining why different incidents require different interpretations. **
That approach is important because refereeing is not simply about deciding whether contact occurred. Officials must determine whether contact constitutes a foul, whether a player has gained an advantage, whether an offence has denied a goalscoring opportunity and whether VAR has sufficient grounds to intervene.
The Growing Influence of VAR
Video Assistant Referee technology has fundamentally changed the way major decisions are reviewed. Before VAR, an official’s decision was generally final once the match continued. Today, certain incidents can be reviewed through multiple camera angles and slow-motion footage.
VAR was introduced to reduce clear and obvious errors, but its use has also generated a new category of controversy. Supporters now debate not only the original decision but also whether VAR should have intervened, whether the correct images were used and whether the review process took too long.
**Gallagher has previously examined some of the most difficult VAR situations in the Premier League. His analysis has included incidents where he believed VAR intervention was appropriate and others where he felt the original decision should have remained untouched. **
The technology has therefore not removed refereeing controversy. Instead, it has changed the nature of the debate.
The Difference Between a Referee and VAR Decision
One of the most important aspects of modern officiating is understanding the different responsibilities of the referee and VAR. The referee remains the primary decision-maker on the pitch, while the VAR reviews specific incidents under defined circumstances.
VAR is not intended to re-referee every moment of a match. Its role is generally associated with major incidents such as goals, penalties, direct red cards and cases of mistaken identity.
That distinction explains why some incidents are reviewed while others are not. A controversial foul in midfield may remain the referee’s decision, while a potential penalty can trigger a review if the relevant criteria are met.
Gallagher’s analysis frequently demonstrates how these boundaries affect decisions. His explanations help show why an incident that looks questionable to supporters does not automatically qualify for a VAR intervention.
Penalty Decisions Remain Particularly Difficult
Penalty decisions are among the most debated calls in football because they can directly determine whether a team receives a major scoring opportunity. The challenge for referees is distinguishing between genuine fouls, normal physical contact and situations where an attacker may have exaggerated contact.
**Gallagher has previously described penalty decisions as involving several possible outcomes, including awarding a penalty, penalising a player for simulation or allowing play to continue. His analysis of Aston Villa’s penalty claims against Liverpool, for example, focused on the competing interpretations of contact inside the area. **
The position of the referee is also critical. An official may have a clear view of one part of an incident but be unable to see contact occurring on the opposite side of a player. VAR can provide additional information, but it does not automatically make every interpretation straightforward.
Understanding Contact Inside the Box
Not every physical collision inside the penalty area is a foul. Football involves contact, and referees must determine whether a player has committed an offence according to the laws of the game.
This is where slow-motion replays can sometimes create confusion. A replay may make a challenge appear more dramatic because the movement is isolated from the speed and context of the original play.
Gallagher’s experience is useful in explaining why referees consider factors such as distance, speed, positioning, the direction of a challenge and whether the defender actually makes a legitimate attempt to play the ball.
The context surrounding an incident can therefore be just as important as the contact itself.
Handball and the Difficulty of Interpretation
Handball decisions have consistently generated controversy because supporters often focus on whether the ball touched a player’s arm, while the laws require officials to consider additional circumstances.
The position of the arm, the player’s movement, the distance between the ball and the player and whether the player has made their body unnaturally bigger can all influence the decision.
**Gallagher has previously analysed handball incidents involving several Premier League clubs, explaining how different arm positions can produce different outcomes. In one Ref Watch discussion, he contrasted an incident where a defender’s raised arm created an advantage with another where an arm was positioned close to the body. **
These examples demonstrate why handball decisions cannot always be reduced to a simple question of whether the ball touched the arm.
Red Cards and Serious Foul Play
Red-card decisions carry enormous consequences because a sending-off leaves a team with ten players. Referees must therefore assess challenges carefully, particularly when a player’s studs, speed or point of contact creates a risk of serious injury.
**Gallagher has frequently assessed red-card incidents. His previous analysis included a challenge involving Nathan Collins of Wolves against Manchester City, where he considered the defender’s use of his studs and the point of contact when evaluating the decision. **
The distinction between a yellow and red card can depend on several factors. A referee must consider whether the challenge uses excessive force or endangers an opponent, rather than simply determining whether contact was made.
This is another area where replay footage can provide valuable information but also create debate. Different angles can reveal details that were difficult or impossible for the referee to see in real time.
Offside Decisions and Marginal Calls
Offside remains another major source of controversy, particularly when a goal is ruled out because a player’s position is marginal. Modern technology can identify extremely small differences in positioning, but the application of the law still requires interpretation.
A player being in an offside position is not automatically an offence. The player must generally become involved in active play according to the relevant provisions of the law.
**Gallagher has previously explained how a player can influence an opponent without touching the ball. In a Tottenham-Crystal Palace incident, for example, he discussed the importance of whether Harry Kane’s position affected the defender’s ability to challenge for the ball. **
These situations demonstrate that offside decisions are about more than drawing a line across the pitch.
The Latest VAR Debate Around Haaland
**Recent Ref Watch coverage has again highlighted the continuing importance of VAR. Sky Sports reported in September 2026 that Gallagher and former Coventry striker Jay Bothroyd examined the controversial decision involving Erling Haaland’s winner against Manchester United. **
The incident became another example of how VAR decisions can dominate the conversation after a major match. When a goal is reviewed, supporters often expect technology to provide an indisputable answer. Yet interpretation can remain part of the process even after multiple replays.
Gallagher’s role in such discussions is to examine the decision through the framework available to referees and VAR officials. That perspective can help separate disagreement with an outcome from questions about whether the correct procedure was followed.
Why Slow Motion Can Change Perception
One of the most interesting aspects of refereeing analysis is the effect of slow-motion video. A challenge that happens at full speed can look completely different when slowed down.
At normal speed, the referee must interpret movement instantly. Slow motion allows viewers to identify the exact moment of contact, the position of a player’s foot and the reaction of the opponent.
However, slowing down an incident can also exaggerate certain elements. A player moving naturally at speed may appear to have deliberately extended a leg when the movement is examined frame by frame.
Experienced referees therefore consider the full-speed incident alongside replay evidence. The objective is not simply to find the most dramatic frame but to understand what actually happened.
