Treble is used in association football to refer to a team winning three trophies in a single season. Honours usually considered to contribute to a treble are the top-tier domestic league competition, domestic cup competitions and continental tournaments; although this depends to some extent on the structure of the football pyramid in a country. Trophy competitions which consist of a single match or a two-leg match (e.g. the FA Community Shield, the Recopa Sudamericana, UEFA Super Cup and FIFA Club World Cup) are generally not counted as part of a treble.

Two phrases sometimes used are a 'continental treble', which involves winning at least one continental trophy, and a 'domestic treble' - usually the domestic league and two secondary tournaments.

This kind of treble consists of a club winning their country's top tier league and a major secondary competition (The Double), in addition to the continental championship, all within a single season.^{[citation needed]} This was first achieved in 1962 by Santos, winning the Campeonato Paulista (state league), Taça Brasil (national league) and Copa Libertadores (continental tournament). Santos remain the only South American club to have achieved this treble. Most countries in the region do not have a domestic cup to enable a domestic double.^{[citation needed]}

Association football, more commonly known as football or soccer, is a sport played between two teams of eleven players with a spherical ball. At the turn of the 21st century, the game was played by over 250 million players in over 200 countries, making it the world's most popular sport. The game is played on a rectangular field of grass or green artificial turf, with a goal in the middle of each of the short ends. The object of the game is to score by driving the ball into the opposing goal.

In general play, the goalkeepers are the only players allowed to touch the ball with their hands or arms (unless the ball is carried out of play, where the field players are required to re-start by a throw-in of the game ball), while the field players typically use their feet to kick the ball into position, occasionally using their torso or head to intercept a ball in midair. The team that scores the most goals by the end of the match wins. If the score is tied at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout, depending on the format of the competition. The Laws of the Game were originally codified in England by the Football Association in 1863 and have evolved since then. Association football is governed internationally by FIFA - Fédération Internationale de Football Association (English: International Federation of Association Football), which organises the FIFA World Cup every four years.

Football refers to a number of sports that involve, to varying degrees, kicking a ball with the foot to score a goal. The most popular of these sports worldwide is association football, more commonly known as just "football" or "soccer". Unqualified, the word football applies to whichever form of football is the most popular in the regional context in which the word appears, including association football, as well as American football, Australian rules football, Canadian football, Gaelic football, rugby league, rugby union and other related games. These variations of football are known as football "codes".

Various forms of "football" can be identified in history, often as popular peasant games. Contemporary codes of football can be traced back to the codification of these games at English public schools in the eighteenth and nineteenth century. The influence and power of the British Empire allowed these rules of football to spread, including to areas of British influence outside of the directly controlled Empire, though by the end of the nineteenth century, distinct regional codes were already developing: Gaelic Football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage. In 1888, The Football League was founded in England, becoming the first of many professional football competitions. In the twentieth century, the various codes of football have become amongst the most popular team sports in the world.
