Football Substitutions Rules: How Many and When

History of Substitutions

The concept of substituting a player mid-match seems so fundamental to modern football that it is difficult to imagine the game without it. Yet for the first 72 years of organised football, there were no substitutes. If a player was injured, their team played with fewer players — a rule that persisted until the 1965-66 season.

The first substitute in English football was Keith Peacock of Charlton Athletic, who replaced an injured teammate in a Second Division match against Bolton Wanderers in August 1965. The rule allowed only one substitute per match, and the substituted player could not return. The rule was introduced initially as a welfare measure — the Football League recognised that forcing teams to play with 10 men after an injury was unfair, particularly in an era when tackling was far more physical and protective equipment minimal.

The 1966 World Cup was the first international tournament to permit substitutes, with each team allowed one. The first substitute in World Cup history was Soviet Union goalkeeper Lev Yashin, who replaced the injured Anzor Kavazashvili in a group match against Italy. Yashin, the legendary "Black Spider," was 36 years old at the time and making his fourth World Cup appearance.

The rules evolved slowly. Two substitutes were permitted from 1988, and three from 1995. The increase to three reflected the growing physical demands of the modern game and the expansion of professional squads. Each increase was driven by the recognition that football had changed — faster, more athletic, and more demanding than the game of the 1960s and 1970s.

The Five-Sub Revolution (2020)

The COVID-19 pandemic of 2020 was a global catastrophe, but it accelerated one of the most significant rule changes in football history. When football resumed after the lockdown, clubs faced an unprecedented fixture congestion. The 2019-20 season had been suspended for three months, and the remaining matches were crammed into a six-week period. Domestic leagues were followed immediately by European competitions, with minimal pre-season preparation for the 2020-21 campaign.

FIFA approved a temporary increase from three to five substitutes to protect player welfare. The rule was optional — each competition could decide whether to adopt it. The Premier League initially adopted five substitutes for the remainder of the 2019-20 season but controversially voted to return to three for the 2020-21 season. The vote was 13-7, with smaller clubs arguing that five subs benefited the bigger clubs with deeper squads.

The debate raged through the 2020-21 season. Managers like Jürgen Klopp and Pep Guardiola argued passionately for five subs, citing increased injury rates and player burnout. Smaller clubs like Burnley, Crystal Palace, and Newcastle argued that the change tilted the playing field toward wealthier clubs. The Premier League's annual general meeting in June 2021 voted to maintain three substitutes, but the issue refused to go away.

In March 2022, the Premier League finally voted 18-2 to adopt five substitutes permanently, effective from the 2022-23 season. The change was driven by mounting evidence of player fatigue and injury, the approach of a winter World Cup in 2022, and growing isolation of the Premier League as the only major competition still using three subs. The vote was a victory for the top clubs and a defeat for smaller clubs who had fought the change for two years.

Current Rules by Competition

Premier League

Teams can name 9 substitutes from the 2024-25 season, up from 7 previously. Five substitutions are permitted per match, to be used in a maximum of three stoppages (excluding half-time). The rules allow substitutions to be made at half-time without counting toward the three stoppage limits. Unused substitutes can still be brought on at any stoppage during the match.

UEFA Champions League

The Champions League permits five substitutions per match with three stoppages. The bench size is up to 12 substitutes for the 2024-25 season under the new format. UEFA also permits a sixth substitute in extra time — each team receives an additional substitution during the 30-minute period.

FIFA World Cup

The World Cup allows the largest benches, with 15 substitutes permitted per match. Five substitutions are allowed during regulation time with three stoppages, plus a sixth in extra time. If a team has not used all five substitutions during regulation time, they receive an additional substitution in extra time, for a maximum of six total.

FA Cup and EFL Cup

The FA Cup allows five substitutions with three stoppages, matching the Premier League rules. The EFL Cup also uses five substitutions, though earlier rounds have smaller bench sizes due to squad registration rules. The EFL Trophy, a competition for lower-league and academy teams, permits rolling substitutions — players can be substituted on and off freely, similar to friendly matches.

Substitution Protocol

The substitution procedure is governed by Law 3 of the Laws of the Game. The substitute must wait at the halfway line and cannot enter the field of play until the player they are replacing has completely left. The departing player should leave at the nearest point on the boundary unless the referee instructs otherwise. Failure to follow this procedure results in a yellow card for the substitute.

The electronic substitution board, introduced in the Premier League in 2011, displays the numbers of the departing and entering players. The board replaced the traditional wooden board and flags used previously. The substitute enters the field at the halfway line, regardless of where the departing player left the pitch. This rule was introduced in 2016 to prevent substitutes from running onto the field in dangerous areas or at distances that would delay the restart.

The referee must be notified of the substitution before it takes place. The fourth official coordinates substitutions, ensuring they occur during a stoppage and that the departing player has left the field. Substitutions made without the referee's permission — "unauthorised substitutions" — result in a yellow card for the offending player and potentially for the manager.

Concussion Substitutes

Concussion substitutes were introduced in 2021 following mounting evidence about the long-term dangers of head injuries in football. The International Football Association Board (IFAB) approved permanent concussion substitutions, allowing teams to make an additional substitution (not counting toward the five regular substitutions) when a player has a suspected head injury.

The protocol is designed to remove pressure on medical staff. If a player shows symptoms of concussion, they can be substituted immediately without using one of the team's regular substitutions. The substitute is permanent — the concussed player cannot return to the field, even if they are later cleared. This encourages teams to err on the side of caution when dealing with head injuries.

The Premier League trialled concussion substitutes in the 2020-21 season before adopting them permanently. The trial included the "additional permanent concussion substitute" rule, where each team could make up to two concussion substitutes per match. The system was praised for prioritising player welfare, though some managers complained that the rule could be exploited by teams seeking tactical advantages.

The issue of head injuries has become increasingly prominent in football. Research by the University of Glasgow found that former professional footballers were three and a half times more likely to die from neurodegenerative diseases. High-profile cases, including the dementia-related deaths of World Cup winners Nobby Stiles, Jack Charlton, and Gordon Banks, have raised awareness of the issue. Concussion substitutes are seen as a crucial step toward protecting players from the long-term consequences of head trauma.

Tactical Substitution Strategies

Substitutions in modern football are tactical weapons as much as welfare measures. Managers use substitutions to change formations, introduce fresh legs, and exploit specific weaknesses in the opposition.

Early substitutions — made before the 60th minute — typically indicate tactical problems or injuries. A manager may substitute a player who is struggling against a specific opponent, change formation in response to the opposition's approach, or replace a player on a yellow card to avoid a red card. The 30th-minute substitution, once rare, has become more common in modern football, particularly when a manager recognises that their tactical plan has failed.

Impact substitutes — attacking players introduced to change the game in the final 20-30 minutes — are the most celebrated substitution strategy. The concept of the "supersub" — a player who consistently scores or creates goals when coming off the bench — is one of football's most valuable assets. Ole Gunnar Solskjaer, who scored 29 goals as a substitute for Manchester United, is the most famous supersub in the Premier League era. His stoppage-time winner in the 1999 Champions League final remains the most famous substitute impact in football history.

Arsène Wenger's 70th-minute substitution policy was legendary at Arsenal. Wenger frequently introduced impact substitutes at exactly 70 minutes, believing this was the optimal time to exploit tired defences. The strategy produced numerous late goals, with Arsenal scoring more goals in the final 20 minutes of matches than any other Premier League team during Wenger's tenure.

Defensive substitutions — bringing on a defender or defensive midfielder to protect a lead — are common in the final 10-15 minutes. The introduction of fresh defensive players can shore up a tiring defence, disrupt the opposition's rhythm, and waste valuable time. Critics argue that defensive substitutions encourage negative football, but managers defend them as pragmatic game management.

Most Famous Substitutions

David Fairclough, Liverpool's "supersub," scored 18 goals as a substitute for Liverpool between 1975 and 1983, including crucial winners against Everton and Saint-Étienne. Fairclough's ability to change games from the bench made him a Liverpool legend.

Ole Gunnar Solskjaer's 1999 Champions League final goal is the most famous substitute moment in football history. Solskjaer came on in the 81st minute and scored the winner at 93:17, completing Manchester United's treble. He later became Manchester United manager, partly on the strength of his status as a club legend.

Xabi Alonso's introduction for Liverpool in the 2005 Champions League final was a tactical masterstroke by Rafael Benitez. Alonso, who had been injured, replaced the ineffective Dietmar Hamann at half-time. His presence in midfield transformed Liverpool's performance, and he scored the equalising penalty in the 3-3 draw before Liverpool won on penalties.

Mario Götze's winning goal for Germany in the 2014 World Cup final came from a substitute. Götze replaced Miroslav Klose in the 88th minute of extra time. In the 113th minute, he controlled André Schürrle's cross on his chest and volleyed past Argentina goalkeeper Sergio Romero. The goal secured Germany's fourth World Cup title. Götze was 22 years old and had been on the pitch for just 25 minutes.

Julian Alvarez's role for Argentina in the 2022 World Cup was unconventional. The 22-year-old started the tournament as a substitute but became a starter after scoring crucial goals from the bench. His performance against Croatia in the semi-final, when he scored two goals and won the penalty for Lionel Messi's opener, demonstrated the value of impact substitutes in tournament football.

Future Changes

The future of football substitutions includes several proposed changes. Sin-bin substitutes — temporary substitutions for players sent to the sin bin — are being trialled at grassroots level. Players sent to the sin bin for 10 minutes would be replaced temporarily, avoiding the numerical disadvantage that currently penalises teams for dissent or tactical fouls.

Temporary substitutions for head injuries have been proposed as an alternative to permanent concussion substitutes. Under the temporary substitute system, a player with a suspected head injury would be replaced for 10 minutes while medical staff assess them. If cleared, the player could return. If diagnosed with concussion, the substitution would become permanent. The temporary system is used in rugby union and has been proposed for football.

The possibility of unlimited substitutions in youth football has been discussed by IFAB. The proposal would allow rolling substitutions in youth matches to maximise playing time for developing players. The rule would not apply to professional football but could be adopted by youth academies and grassroots competitions.

Electronic substitution boards, already used in the Premier League and Champions League, will become mandatory across all FIFA competitions. The FIFA Quality Programme now certifies electronic substitution boards, ensuring consistency across competitions. The boards display the player numbers, the type of substitution, and the stoppage number, providing clarity for players, officials, and broadcasters.

The substitution rule has come a long way from Keith Peacock's pioneering moment in 1965. From one substitute to five, from permanent to temporary, from welfare measure to tactical weapon — substitutions have transformed football. The next evolution, driven by concussion awareness and player welfare concerns, will continue to shape the game for decades to come.
