How does the Premier League work? A complete guide

The Premier League is a 20-club competition where each team plays 38 matches and the bottom three are relegated. The rules governing the league go deeper than a simple points tally: tiebreakers can decide titles, the homegrown quota shapes squad building, and European qualification shifts based on cup results. Understanding these mechanisms is the difference between following the league and truly knowing it.

The mechanism

Every club plays 38 matches - one home, one away against each opponent. A win earns three points, a draw earns one. The table is sorted by points, then goal difference (goals scored minus goals conceded), then goals scored, then head-to-head record between the tied teams. If those four tiebreakers fail to separate teams and the position decides the title, relegation, or European qualification, a play-off at a neutral venue is used. That has never happened in the Premier League, but the rule exists.

Squad rules are often misunderstood. Each club must submit a 25-player squad for players over 21. At least 8 of those must be homegrown - defined as having been trained in England or Wales for three years before turning 21. Players under 21 do not count against the 25, which is why clubs stockpile young talent. The rule aims to protect domestic development, but it also creates a market for English-trained players who might not otherwise start.

Substitutions changed in 2020. Teams now make five subs per match, but they can only use three windows (plus half-time) to make them. This rewards deep benches and tactical flexibility. Managers can change shape late, but they cannot break the flow by making five separate stoppages.

European qualification follows a standard structure: the top four enter the Champions League league phase. Fifth place and the FA Cup winner go to the Europa League. The League Cup winner goes to the Conference League play-off. If a cup winner already qualified via league position, that place passes down to the next highest league finisher. Additional Champions League spots can be earned through UEFA coefficient performance, which rewards the strength of the league as a whole.

Fantasy Premier League (FPL) is a layer of complexity for fans. Each manager picks a 15-player squad with a 100.0m budget, maximum three players from any club. Scoring differentiates by position: a goalkeeper or defender gets 6 points for a goal, a midfielder gets 5, a forward gets 4. An assist earns 3. Clean sheets are worth 4 for a goalkeeper or defender, 1 for a midfielder. The bonus points system (BPS) awards 3, 2, or 1 extra points to the top three performers in each match based on a composite score. Captain scores double. A transfer beyond the free allowance costs -4. Yellow cards cost -1, red cards -3, own goals -2, penalty misses -2. Goalkeepers get +1 per three saves and 5 for a penalty save. Every two goals conceded costs a goalkeeper or defender -1. The system rewards defensive solidity from the back and attacking output from forwards, but the bonus points can overturn raw goal contributions.

History and evolution

The Premier League was founded on 20 February 1992, when the 22 First Division clubs broke away from the Football League to negotiate their own broadcast deals. The first season was 1992/93 with 22 clubs. That was reduced to 20 in 1995/96, where it has stayed. The reduction meant fewer matches but higher quality, and the league's global appeal grew with the influx of broadcast money.

The homegrown rule was introduced later, partly to comply with UEFA regulations and partly to protect the England national team. The substitution rule changed from three to five in 2020, initially as a COVID-19 measure, then made permanent. The tiebreaker system has remained largely unchanged, though the play-off option has never been triggered.

Edge cases

Tiebreakers matter most in tight seasons. When Manchester City won the title in 2012 on goal difference, the Premier League had to rely on its second tiebreaker because points were level. Had goal difference also been equal, goals scored would have decided it. If that had failed, head-to-head. The system is designed to be exhaustive, but it is not perfect. A play-off would be a one-off match at a neutral venue, likely at Wembley, and would be the highest-stakes game in the league's history.

Relegation is decided by the same tiebreakers. In 2020, Bournemouth went down on goal difference with 34 points, while Watford stayed up on goals scored. That is brutal, but the rules are known before the season starts.

European qualification edge cases: if the FA Cup winner finishes in the top five, the Europa League place passes to the next highest league finisher. If the League Cup winner finishes in the top six, the Conference League place passes down. The additional Champions League spots via coefficient are rare but have given England four or five spots in recent years.

FPL edge cases: a player who plays 59 minutes gets 1 appearance point; 60 minutes or more gets 2. A goalkeeper who concedes two goals loses 1 point, but a clean sheet plus saves can still yield a high score. The bonus points system is opaque to many managers, but it rewards defenders who make tackles, interceptions, and passes. A defender who scores a goal and keeps a clean sheet can hit 15 points if they also get bonus.

Key takeaways

• The Premier League has 20 clubs playing 38 matches each, with 3 points for a win and 1 for a draw.
• Tiebreakers are points, goal difference, goals scored, head-to-head, then a play-off for critical positions.
• Squad rules require a 25-man list with at least 8 homegrown players; under-21s are exempt.
• European qualification: top four to Champions League, fifth plus FA Cup winner to Europa League, League Cup winner to Conference League, with possible extra spots via coefficient.
• FPL scoring rewards defenders and goalkeepers more for goals and clean sheets, with bonus points added from BPS.

FAQ

How many teams get relegated from the Premier League? Three teams are relegated to the Championship each season. Two are automatically promoted, and one via the play-off.

What happens if two teams are tied on points at the end of the season? The tiebreakers are goal difference, then goals scored, then head-to-head record. If still level and the position decides the title, relegation, or European qualification, a play-off match at a neutral venue is used.

How many substitutions are allowed in a Premier League match? Five substitutions per match, but they can only be made in a maximum of three windows (plus half-time). This was increased from three in 2020.

What is the homegrown rule? Each club's 25-player squad for players over 21 must include at least 8 players who have been trained in England or Wales for three years before turning 21. Under-21 players are not counted in the 25.

When Arsenal finish in the top four, they qualify for the Champions League. Liverpool have used the homegrown rule to develop academy talents like Trent Alexander-Arnold. In FPL, a player like Mohamed Salah scores 5 points for a goal, but a defender scoring the same goal gets 6. That is the kind of detail that separates casual fans from those who truly understand the league.
