Most explanations of the laws of football are either the official text, which is written for referees, or a summary so short it leaves out the part you were asking about. This page sits between the two. Every question below is answered properly here, and each one links to a longer piece if you want the reasoning rather than the rule.
It covers what happens on the pitch, how the competitions are structured, the administrative rules that decide who can play and what a club can spend, and the practical business of actually watching a match. Where a rule changed recently, the answer says so, because a great deal of what people believe about football law was true until fairly recently.
Decisions on the pitch
The laws that get argued about most, and that referees apply several times in every match.
Can a goalkeeper pick up a back pass?
Not if a team-mate deliberately kicked it to them, and not from a team-mate's throw-in. A ball deliberately headed, chested or kneed back is fine. The test is whether the pass was intended, not whether it was intended for the goalkeeper — so a miskicked clearance still counts, and a deflection off an opponent does not. Read the full explanation.
How does a penalty shootout work?
Five kicks each, taken alternately, then sudden death if the scores are level. Every eligible player must take one before anyone takes a second. A retake is forced when the goalkeeper leaves the line and saves it, or when encroachment changed the outcome — never when the kick was scored anyway. Read the full explanation.
What do the referee's signals mean?
Both arms sweeping forward is advantage. One arm straight up and held there is an indirect free kick, until a second player touches the ball. An arm pointed and dropped is a direct free kick. A point to the centre circle is a goal. A rectangle drawn in the air is a video review. Read the full explanation.
How is stoppage time calculated?
The referee adds time lost to substitutions, celebrations, injuries, cards, video reviews and deliberate time-wasting. Ordinary throw-ins and the walk to a free kick are not counted. The figure on the board is a minimum, and anything happening during the added period is added to it. Read the full explanation.
How does a VAR decision actually get made?
VAR may only look at goals, penalties, direct red cards and mistaken identity, and only intervenes on a clear and obvious error. Factual matters such as offside are decided by the video official; subjective ones are sent to the referee's own screen, because the judgement stays with the person on the pitch. Read the full explanation.
How many substitutes are allowed?
Five, but only in three windows excluding half-time, which is the clause that does most of the work. A concussion substitute is additional and does not count against either limit, so a club loses nothing competitively by removing a player who has taken a blow to the head. Read the full explanation.
How long does a football match actually last?
About one hour fifty-five minutes end to end for a league match, and closer to three hours for a knockout tie going to penalties. The ball is genuinely in play for roughly fifty to sixty minutes of that, which is why adding stoppage time changes the experience less than people expect. Read the full explanation.
Do away goals still count double?
No. UEFA abolished the rule across its club competitions, so a tie level on aggregate goes to extra time and then penalties regardless of where the goals were scored. Several other competitions still use it, generally those that cannot afford a third match. Read the full explanation.
How are referees appointed and assessed?
Officials climb a pathway level by level, and appointments are made centrally rather than by the clubs. Assessment is mostly about positioning, consistency of threshold and player management rather than a count of correct decisions, which is the largest gap between how officiating is judged inside the game and outside it. Read the full explanation.
Competition formats
How the tournaments are actually structured, including the parts that changed recently.
How does the Champions League league phase work?
Thirty-six clubs in one table, each playing eight different opponents, two from each of four pots. The top eight go straight to the last sixteen, ninth to twenty-fourth enter a playoff round, and the rest are eliminated with no consolation competition to drop into. Read the full explanation.
How is the Champions League draw made?
By software, because the constraint set no longer permits a hand draw. No club may face a side from its own country or more than two from any other, and a legal early pairing can leave a later club with no valid opponent — a dead end a person with a bowl of balls cannot see coming. Read the full explanation.
How do English clubs qualify for Europe?
Top four for the Champions League, sometimes fifth when the country earns an extra place through the coefficient. The FA Cup winners enter the Europa League and the League Cup winners the Conference League playoff, with places passing down the table when a cup winner has already qualified. Read the full explanation.
How do UEFA coefficients work?
A country's score is the points its clubs earn divided by the number it entered, averaged over five seasons. That division is why early exits cost more than deep runs gain, and the five-year window is why a league's standing usually describes a version of itself that no longer exists. Read the full explanation.
Does the FA Cup still have replays?
No. Ties are settled on the day throughout the competition, using extra time and penalties. The loss falls almost entirely on small clubs drawn away at large ones, for whom a home replay could fund a season — which is a handful of ties a year rather than a general transfer of money out of the lower leagues. Read the full explanation.
Why do clubs field weakened teams in the League Cup?
Because nothing requires them not to. The competition sets a minimum number of regular players, and it is low enough that nine or ten changes still comply. Setting it higher would be unenforceable, since any club told to field its first eleven can report injuries nobody can disprove. Read the full explanation.
How does the English football pyramid work?
Promotion and relegation connect every level from the Premier League down to regional leagues. The two genuine chokepoints are the step where full-time football becomes necessary and the single automatic promotion place out of the National League, which is the narrowest gate in English football. Read the full explanation.
How is the fixture list made?
By constraint solver, after every other calendar has been set. International windows, European dates and cup rounds are fixed first, and the league season is fitted into what is left. The scheduler has no model of which clubs are good, so a run that looks punishing in hindsight was unremarkable when it was drawn up. Read the full explanation.
Squads, transfers and money
The administrative rules that decide who can play and what a club can spend.
How does the transfer window work?
Registration is what the window governs, not negotiation. A deal needs the clubs to agree a fee, the player to agree terms, and the registration to be lodged — and international clearance has to pass through the world governing body, which is why deals agreed late in the day still fail. Read the full explanation.
What are the 25-man squad and homegrown rules?
A club registers twenty-five players over twenty-one, of whom at least eight must be homegrown, with under-21s unrestricted and unlimited. Homegrown means trained in the country for three years before turning twenty-one — not eligible for the national team, which is why the rule has done less than intended. Read the full explanation.
How do football loans work?
The parent club keeps the registration and the two clubs split the wages, with or without a fee. A recall clause has to be written in; without one the player stays for the term. Many loans are not about development at all, but about wage relief, a pre-agreed transfer, or a full squad list. Read the full explanation.
What are PSR and how do clubs lose points?
Profitability and Sustainability Rules cap losses across a rolling three-year period, with deductions for infrastructure, youth and women's football. The sanction is points because a fine would be paid by the same owner who funded the overspend, and the process is slow because a breach cannot be established until the final year's accounts are filed. Read the full explanation.
How is Premier League prize money split?
Three pots: an equal share of domestic broadcast money, merit payments by league position, and facility fees for televised appearances. The gap between consecutive positions is small. The gap between seventeenth and eighteenth is not, because relegation removes the central payment entirely. Read the full explanation.
Watching and following football
The practical questions about rights, timings and access that the rules above create.
Why do kick-off times change?
Mostly broadcast selection, announced in batches several weeks ahead. Policing and safety instructions override everything and arrive with less notice. European progress and cup draws rearrange midweeks. The 3pm Saturday slot barely moves, because it cannot be televised in the UK anyway. Read the full explanation.
Why do matches get postponed, and what happens to my ticket?
Weather, pitch condition, safety and unavailable squads are the four reasons. A ticket for a postponed match is normally valid for the rearranged date without any action, and refundable on request if you cannot attend. Travel and accommodation are not covered by anyone. Read the full explanation.
Which football is protected for free-to-air television?
A government-set list covering tournament finals and certain international matches, split into full live protection and highlights-only protection. Domestic league football is not on it, and every proposal to add it has been rejected on the grounds that it would reduce what the competition can distribute to clubs. Read the full explanation.
How do I watch the Premier League in 2026/27?
Sky Sports and TNT Sports between them carry every televised match, with no overlap. That leaves 113 of the 380 fixtures not shown live in the UK at all, almost all in the protected Saturday 3pm window. Highlights remain free to air. Read the full explanation.
How do away ticket allocations work?
Visiting clubs receive a set share of capacity, capped for segregation and policing reasons and distributed by a loyalty scheme. Published figures are rarely round because the safety officer removes rows first, and half-empty away ends are usually a returned allocation or a segregation buffer rather than indifference. Read the full explanation.
How do I follow a club from another country?
Start with the competition rather than a search engine, because rights are sold country by country. The 3pm blackout is a UK restriction and does not travel. Store fixtures with a time zone attached, since the clocks in different countries change on different weekends. Read the full explanation.
How do I follow a match without watching it?
Radio is effectively live, television is seconds behind, internet feeds can be minutes behind, and goal notifications are frequently the fastest of all. That ordering is why alerts spoil streams, and why the old trick of muting the television and turning up the radio no longer works. Read the full explanation.
How do I watch the Women's Super League?
A meaningful share of matches stay on free television and the rest sit behind a subscription, a split revisited every rights cycle. The league turned fully professional in 2018, and the deals since have balanced income against being watchable by an audience still forming the habit. Read the full explanation.
Why do international breaks exist?
Because release for official international windows is compulsory, and clubs cannot refuse. They may contest fitness through medical reports but cannot restrict how a player is used once released. Compensation covers tournaments rather than the routine windows where most of the travel and injuries happen. Read the full explanation.
