18 Football Facts That Surprise Even Big Fans

Think you know football? The world's game is so old, so global and so deep that even devoted fans keep discovering things that surprise them. Here is a collection of genuinely interesting facts about football's history, rules and culture — the kind of knowledge that makes you a better quiz teammate and a sharper footbadle player. Some you will know; we bet a few will catch you out.

On the laws of the game

1. Football's rules are governed by a body older than most clubs. The International Football Association Board, which decides the Laws of the Game, was founded in 1886 and still holds that authority today.

1. A match doesn't have to be 90 minutes. Ninety minutes is the standard, but the laws allow for added time, extra time and, in knockout competitions, penalty shootouts — and the referee is the official timekeeper.

1. You can't be offside from a throw-in. It is one of football's quirks: the offside law is suspended for throw-ins, goal kicks and corner kicks.

1. The penalty kick is younger than the game. Football was played for years before the penalty was introduced; the idea of awarding a free shot from twelve yards for a foul came later in the sport's development.

1. A goalkeeper picking up a back-pass is a relatively modern foul. The rule preventing keepers from handling a deliberate back-pass from a teammate's foot was introduced to speed the game up and stop time-wasting — older footage shows keepers scooping up back-passes freely.

On history and origins

1. Modern football was codified in England, when a set of standardised rules was drawn up in the 1860s to unify the many local variations of the game being played.

1. The word "soccer" is British in origin. It came from "association football" — the "assoc" was turned into "soccer" — and was widely used in Britain before becoming associated mainly with North America.

1. The oldest football clubs predate many countries' leagues. Several clubs around the world trace their origins to the nineteenth century, making them older than many of the competitions they now play in.

On the global game

1. Football is played in more countries than almost any other sport, and the international governing body has more member associations than the United Nations has member states.

1. The World Cup is one of the most-watched events on earth, with the final drawing a global audience in the hundreds of millions — a scale few other broadcasts ever reach.

1. Promotion and relegation make European football unusually open. Unlike closed-league sports systems, a small club can, in theory, rise through the divisions to the top flight — and a giant can fall.

On the culture

1. Shirt numbers once mapped to positions. In the traditional system, 1 was the goalkeeper, 2–6 the defenders and midfielders, and so on — which is why the number 10 became synonymous with the creative playmaker.

1. Squad numbers changed the game's romance. When leagues moved to fixed squad numbers, players kept the same number all season regardless of position, and iconic numbers became part of personal brands.

1. Derbies are about geography as much as football. Many of the fiercest rivalries are between clubs from the same city or region, where bragging rights are local and personal.

1. Stadium atmosphere is engineered. Features like steep stands, safe-standing terraces and roofs that trap noise are deliberately designed to amplify the crowd — German grounds are famous for it.

On the things that decide matches

1. Set pieces decide a huge share of goals. Corners, free kicks and penalties account for a significant portion of goals scored, which is why elite teams drill them so obsessively.

1. Home advantage is real but shrinking. Playing at home has historically boosted results, though the size of the effect has changed over time and varies by competition.

1. The best defenders age better than the best attackers. Because defending and goalkeeping rely so heavily on reading the game and positioning rather than raw speed, those players often perform at the top level for longer.
