VAR in Europe’s Big Five Leagues: Latest Data, Errors & Trends

Back to contents ↑

Comparing VAR across Europe’s Big Five is harder than comparing goals, shots or league tables. There is no single public database in which the Premier League, La Liga, Bundesliga, Serie A and Ligue 1 report every review, missed intervention and corrected decision according to an identical methodology.

This analysis therefore prioritises official league, federation and rule-making sources. These include the Premier League and its Key Match Incident framework, the DFB and Bundesliga, Spain’s RFEF, Italy’s Lega Serie A, France’s LFP and Ligue 1 platforms, and the International Football Association Board.

Seasons, Competitions & Metrics

What the Data Can – and Cannot – Prove

The previous version of this analysis used precise Big Five percentage changes for penalties, red cards, added time and home advantage. Those figures have been removed because the underlying cross-league calculation could not be reconstructed from a consistent set of primary-source data.

The updated approach separates observed league outcomes from documented VAR interventions and labels historical comparison points by season or publication date rather than presenting them as timeless averages.

VAR remains an assistance system rather than a second referee who re-officiates every decision. For subjective incidents, intervention is still built around the clear-and-obvious-error principle or a serious missed incident within a reviewable category.

Factual elements such as offside are different because tracking technology can provide objective positional information. This explains why a marginal offside and a borderline penalty challenge can follow very different review processes.

Which Decisions Can VAR Review?

Why VAR Rules Differ Between Leagues

IFAB defines the international framework, but some measures are optional for competitions. Two leagues can therefore operate under the same Laws of the Game while using different practical VAR protocols.

The most useful comparison is not a league table declaring one VAR system “best”. The five competitions publish different levels of detail and operate with different intervention cultures.

Premier League

England provides the clearest public framework for measuring high-impact refereeing performance through the independent Key Match Incident Panel.

The rebound in 2025/26 prevents an overly simple conclusion that VAR accuracy automatically improves every year. The total remained below the first two KMI seasons, but progress was not linear.

Efficiency also improved. Reported VAR delay fell from around 64 seconds per game in 2023/24 to approximately 47 seconds in 2025/26.

England introduced semi-automated offside technology on April 12, 2025, primarily to improve speed, efficiency and consistency.

La Liga

Spain has moved increasingly toward technological integration and public refereeing explanation. The RFEF publishes review material around debated decisions, giving supporters more visibility into how individual incidents are assessed.

The biggest 2026/27 development is connected-ball technology in Primera División, integrated with VAR and semi-automated offside technology.

Sensor-based ball data can help establish the precise moment of contact with the ball. Combined with player tracking, that can improve the factual stage of an offside review.

Early 2026/27 La Liga results are not used here to make season-long claims because the sample remains too small.

Bundesliga

Germany provides one of the clearest examples of why league-wide outcome statistics should not automatically be described as “VAR effects”.

VAR was already mature in both seasons. The jump therefore cannot sensibly be explained by the existence of video review alone.

Historical DFB benchmarking also showed meaningful differences in intervention culture between leagues, with the Bundesliga, Serie A and La Liga at around 0.40 interventions per match in that comparison, compared with 0.27 in Ligue 1 and 0.23 in the Premier League.

Italy was one of the first Big Five leagues to implement VAR permanently, beginning in 2017/18. By 2025/26, video review was therefore no longer a new intervention but part of an established refereeing system.

These figures are useful context but should not be interpreted as direct VAR indicators. Once technology has been embedded for almost a decade, season-to-season changes increasingly reflect several interacting variables rather than an introduction effect.

France produced some of the most striking disciplinary and penalty fluctuations during 2025/26. Ligue 1 reported 32 penalties in only the opening seven matchdays, equivalent at that stage to roughly 0.51 penalties per game.

During the first part of the campaign, Ligue 1 also reported 68 attempted penalties with 45 converted, producing a conversion rate of roughly 66%.

France is especially interesting for transparency. In April 2026 the LFP tested live amplification of selected referee communication related to VAR, making information available to stadium spectators and broadcast viewers.

Premier League KMI Data

The Premier League offers the strongest longitudinal public dataset for analysing VAR errors because its Key Match Incident Panel assesses high-impact incidents independently of the match officials themselves.

The 2025/26 increase was driven primarily by missed interventions rather than an explosion in incorrect overturns. That distinction matters: a system can make fewer actively wrong changes while still missing incidents in which it should have intervened.

Why “VAR Accuracy” Is Difficult to Compare

Accuracy percentages can look definitive while measuring very different things. One figure may represent all key match incidents; another may measure only VAR interventions; another may include factual offsides; and another may count missed interventions as errors.

Penalties are often used as the simplest proof that VAR has changed football. The argument is intuitive: more camera angles reveal fouls that the referee could not see, so penalty numbers should rise.

In practice, the data is much less stable. The Bundesliga’s recent swing is the clearest example.

Bundesliga’s 2025/26 Penalty Spike

The obvious lesson is not that VAR suddenly became twice as aggressive. The technology and general review structure existed in both seasons.

More plausible contributing factors include the specific incident mix, refereeing directives, handball interpretation, holding at set pieces, player behaviour and the threshold at which the video assistant recommends an on-field review.

Does VAR Actually Cause More Penalties?

There are several mechanisms operating at the same time. VAR can detect previously missed fouls; players may change their behaviour because they know incidents are reviewable; handball or holding interpretations can change; and the natural distribution of incidents varies from season to season.

This is why a clean causal statement such as “VAR increased Big Five penalties by X%” is too strong without a consistently defined and controlled dataset.

Direct Red Cards

Red-card statistics are even more difficult to attribute directly to VAR than penalties. A league may record more dismissals because referees are stricter, because more serious incidents occur or because VAR detects offences that were missed in real time.

These figures do not support a universal “VAR reduces red cards” theory. Disciplinary outcomes remain strongly league- and season-dependent.

Second Yellows and the New VAR Rules

From July 2026, VAR can assist when there is clear evidence that a second caution which produced a red card was itself incorrect.

This is significant because an incorrect second caution has the same numerical consequence as an incorrect straight red card: the team plays with ten players.

How Long Do VAR Reviews Take?

VAR’s effect on match flow is often judged by the longest controversial review rather than the average impact across hundreds of matches.

Earlier in the implementation era, the DFB reported an average intervention duration of 83 seconds in its Bundesliga sample. That historical number is not directly equivalent to the newer Premier League delay metric, but it illustrates how review efficiency has become a formal performance target.

Perception vs. Measurable Delay

A 30-second check that confirms a decision is quickly forgotten. A three-minute review that cancels a winning goal becomes a defining memory.

The emotional cost is also different from pure elapsed time. Even when average delay falls, supporters may hesitate before fully celebrating because a possible offside review remains in the background.

Offside is where football’s VAR systems are becoming most technologically advanced. Instead of relying entirely on an operator to construct virtual lines manually, semi-automated systems use player tracking to identify relevant body positions and accelerate the process.

SAOT in the Premier League

The Premier League introduced semi-automated offside technology on April 12, 2025, beginning with Matchweek 32 of the 2024/25 season.

The system uses optical player tracking to support virtual offside-line placement and creates visual graphics for stadium and broadcast audiences. The league emphasised speed, efficiency and consistency rather than a change in the fundamental accuracy standard.

Spain’s Connected-Ball VAR System

Spain moved further for 2026/27. On August 13, 2026, the RFEF confirmed that connected-ball technology would be available in Primera División and integrated with VAR and SAOT.

Sensor-based ball information can help identify the precise moment of contact, one of the most important inputs for determining an offside position.

VAR and Home Advantage

One of the most interesting academic questions is whether video review reduces subconscious home bias. Referees working in a noisy stadium may be influenced by crowd pressure even without consciously favouring the home team.

Video review can theoretically weaken that mechanism because major decisions receive a second assessment away from the immediate emotional pressure around the incident.

However, changes in home wins, away goals or away points cannot be attributed to VAR alone. Tactical evolution, team quality, scheduling, substitutions, added-time policies and pandemic-era crowd restrictions can distort simple pre/post comparisons.

Monitoring and Deterrence Effects

VAR can influence behaviour even when no review occurs. Players know that violent conduct, holding, handball and penalty-area incidents may be replayed from several angles.

This creates two competing mechanisms. The monitoring effect means previously unseen offences can be detected. The deterrence effect means players may avoid some offences because they expect them to be detected.

Those mechanisms help explain why raw statistics can move in either direction. Better monitoring can initially increase sanctions; successful deterrence can reduce the underlying number of offences.

Referee Audio and Public Explanations

Accuracy alone has not solved VAR’s credibility problem. Supporters also want to understand what is being checked, why the referee has gone to the monitor and which interpretation produced the final decision.

Ligue 1 took an important step in April 2026 when the LFP tested live amplification of selected referee communication related to VAR.

The stated objectives included clearer explanation, improved understanding and a better spectator experience.

England has pursued the same goal through its Premier League Match Centre, public explanations and programmes such as “Match Officials Mic’d Up”, even though full live referee-VAR audio remains restricted.

Which League Is Most Transparent?

The Premier League currently provides the strongest systematic public error assessment through the KMI Panel. Spain increasingly publishes detailed incident reviews, while France has moved aggressively toward public referee communication.

The strongest conclusion from the latest evidence is that VAR has entered a second phase of development.

The first phase was adoption: deciding whether competitions should use video review and establishing protocols for goals, penalties, red cards and mistaken identity. Across Europe’s Big Five, that argument is largely over. VAR is institutionally embedded.

The second phase is optimisation. The key questions are now how often VAR should intervene, how quickly factual information can be established, how subjective thresholds should be applied and how decisions should be communicated to supporters.

The Premier League illustrates the accuracy problem well. Moving from 38 VAR errors to 18 in two seasons represented major progress, but the rebound to 25 in 2025/26 shows why a single percentage should never be treated as proof that the problem is solved.

Germany’s penalty data makes a similar point. A mature VAR competition almost doubled its penalty total from one season to the next. That volatility strongly suggests that refereeing outcomes are shaped by much more than whether a video assistant exists.

Spain’s connected ball and England’s SAOT show where technology has the clearest potential: factual tasks. Machines are particularly useful for answering “where was the player?” and “when exactly was the ball touched?”. They are much less capable of answering football’s most controversial question: “Was that contact enough for a foul?”

What should not be done in September 2026 is extrapolating from only a few rounds of league football. A handful of penalties, red cards or overturned goals can radically distort per-match rates at the beginning of a season.

VAR has changed elite football, but the latest Big Five data shows that its effects are less uniform than many headline statistics suggest.

The Premier League demonstrates that error levels can improve dramatically and then move backwards again. The Bundesliga shows that penalty frequency can almost double from one mature VAR season to the next. Ligue 1 demonstrates that disciplinary patterns can change sharply, while Spain is showing how sensor technology can increasingly support factual decisions.

That makes it misleading to reduce VAR’s impact to one claim such as “more penalties”, “fewer red cards” or “97% accuracy”. The technology interacts with refereeing philosophy, interpretation, player behaviour and competition-specific protocols.

What is clearer is the direction of travel. VAR is becoming more automated for factual decisions, more narrowly defined for subjective intervention and more transparent in the way decisions are communicated.
