Assistant referee (association football) An assistant referee is a match official in association football who supports the referee by judging offsides, fouls near touchlines, and other incidents while patrolling the touchline. They assist in enforcing Laws of the Game established by the Fédération Internationale de Football Association and work within teams including the referee (association football) and fourth official at domestic and international competitions such as the FIFA World Cup, UEFA Champions League, and English Football League.

Role and Responsibilities

Assistant referees are responsible for signaling offsides, indicating when the ball has left play, and assisting with incidents the referee cannot see during matches organized by bodies like CONMEBOL, UEFA, CONCACAF, AFC, and national associations such as the The Football Association and Deutscher Fußball-Bund. They also assist with substitution procedures governed by tournaments like the UEFA European Championship and inter-club competitions such as the FA Cup. In elite competitions such as the Premier League and La Liga, assistant referees often collaborate with additional assistant referees appointed by organizations like the European Club Association. Responsibilities extend to observing conduct related to disciplinary procedures under rules set by International Football Association Board and reporting incidents for retrospective action by disciplinary committees like those of UEFA and FIFA.

Signals and Equipment

Assistant referees use standardized signaling devices and equipment including flags approved by IFAB, electronic communication systems supplied by manufacturers used in competitions like the FIFA Club World Cup and UEFA Europa League, and positioning tools recommended by national associations such as the Scottish Football Association. Flags are used to signal offside, fouls, and substitutions, while headsets provide constant links to the referee as used in World Cup qualification matches and UEFA Champions League fixtures. At elite levels, technology like Video Assistant Referee systems, goal-line technology endorsed by IFAB and implemented in tournaments such as the FIFA World Cup and Premier League complements traditional equipment, though assistants retain primary duties for on-field observations.

Offside and Decision-Making

One of the assistant referee's principal duties is adjudicating offside under Law 11 as maintained by IFAB. This requires judging position relative to opponents such as the last outfield player and goalkeeper, as seen in matches involving clubs like Real Madrid CF, FC Barcelona, Manchester United F.C., and national teams including Brazil national football team and Germany national football team. Decision-making combines visual acuity, anticipation, and cooperation with the referee and VAR teams used in competitions like UEFA Euro 2020 and FIFA World Cup 2018. When uncertainty arises, protocols from organizations like FIFA and UEFA provide for VAR review or referee consultation, as occurred in high-profile fixtures such as UEFA Champions League Final matches and World Cup qualification play-offs.

Positioning and Movement

Assistant referees maintain touchline positions to keep level with the second-last defender, a technique taught by bodies like The Football Association and Deutscher Fußball-Bund and practiced at stadiums including Wembley Stadium, Camp Nou, and Old Trafford. Movement patterns involve diagonal runs, sprinting during transitions, and aligning with plays in competitions under the jurisdiction of CONMEBOL and AFC. Proper positioning is emphasized in referee development programs run by confederations such as CONCACAF and national federations including Royal Dutch Football Association to improve accuracy in leagues like Eredivisie, Serie A, and Bundesliga.

Communication with Match Officials

Assistant referees communicate through flag signals, body language, and radio headsets, coordinating with referees, fourth officials, and VAR teams managed by organizations like IFAB and FIFA. Effective communication protocols are integral in high-stakes tournaments such as the FIFA World Cup and UEFA European Championship, where assistants liaise with match commissioners and refereeing committees from UEFA and CONMEBOL. They may also file match reports to disciplinary bodies including national associations and continental confederations following incidents in competitions like the FA Cup and Copa Libertadores.

Appointment, Training, and Qualifications

Appointments are made by refereeing committees within bodies like FIFA, UEFA, CONMEBOL, and national associations such as The Football Association and Brazilian Football Confederation. Training programs include fitness testing, Law of the Game seminars, and practical assessments used by organizations like Deutscher Fußball-Bund and Royal Spanish Football Federation for leagues including La Liga and Bundesliga. Qualifications range from grassroots certification overseen by county associations in countries like England and Scotland to elite FIFA badges awarded to officials serving in FIFA Club World Cup and World Cup tournaments.

Notable Historical Developments and Rule Changes

The role evolved from linesmen to assistant referees following IFAB decisions and shifts in competitions such as the introduction of additional assistant referees in UEFA competitions and adoption of VAR in FIFA World Cup 2018. Rule changes by IFAB affecting offside interpretations, signal protocols, and substitutions have shaped modern practice in leagues like the Premier League and tournaments like the UEFA Champions League. High-profile incidents in matches involving teams such as AC Milan, Liverpool F.C., and national teams like Argentina national football team have prompted amendments to guidance for assistants.

Controversies and Criticism

Assistant referees have faced scrutiny over missed offside calls and disputed decisions in fixtures such as UEFA Champions League Final matches and international qualifiers, drawing criticism from clubs like Manchester City F.C. and national federations such as Brazilian Football Confederation. Debates about the accuracy of human judgment versus technology have involved stakeholders including IFAB, FIFA, broadcasters such as Sky Sports and BBC Sport, and players from clubs like Juventus F.C. and Paris Saint-Germain F.C.. Controversies have led to proposals for expanded VAR use and changes to assistant referee training advocated by refereeing committees within UEFA and national associations.
