Soccer is a ball sport in which two teams compete with the goal of scoring more goals than their opponents to win the game. Game time is usually two 45-minute periods, plus overtime and, if necessary, extra time and/or penalty kicks. A team usually consists of eleven players, one of whom is the goalkeeper. The ball may be played with the whole body except the arms and hands; Mainly it is kicked with the foot. Only the goalkeeper (inside his own penalty area) - or the field players when taking a throw-in - may touch the ball with their hands.
The success of soccer is based first of all on its simplicity. The expenditure of means and equipment is relatively low (see e.g. street soccer), which made it very popular in many developing countries, and it is easily understood or even taken for granted by newcomers and spectators. Second, comparatively few goals are scored, which increases the value of a goal and makes the games more exciting, since superior or better-placed teams cannot win as often or be determined as winners early as in other ball sports. However, these peculiarities are counteracted in recent times by more complicated regulations (including changes to the offside rule) and in top-level soccer ever greater (technical) effort (including the video evidence) should lead to a "fairer" soccer.
Football originated in the second half of the 19th century in Great Britain and spread to continental Europe and other continents from the 1880s and 1890s . It is considered the world's most popular team sport. Unlike other sports (such as handball), top clubs in soccer usually developed only in large cities, which can boast the very elaborate infrastructure with recently increasing demands.
