The official FIFA soccer rules explain that every game is played between two teams, each containing not less than eleven players and not more than fourteen players including the coach. All youth clubs play with up to nine players, except in the case of junior national teams where only five are allowed.
It is important to keep in mind that in youth soccer tournaments a smaller number of players is permitted than in a professional game. As a consequence, the rules will usually be more lenient than in a professional game. In many cases you are not allowed to kick the ball with both feet, although the referee will still whistle for foul play. Another rule is to have one player on each team, including the goalkeeper, and the opposing players must be lined up in a manner that is familiar to you.
Soccer is very much a spectator sport, as the majority of the action takes place away from the spectators and camera lens. Consequently, there are some very specific rules that must be followed for the game to be played in accordance with the soccer rules.
As previously stated, there are many instances where a player can receive a yellow or red card for foul play. The following is a brief list of what can cause a player to receive a card in soccer:
Foul-Kicking: A player who is unable to control his stick when he kicks the ball can receive a card for foul-kicking. This may be done from behind the goal line, or from above the halfway line.
Dangerous-Playing: If a player who is in an offside position starts dribbling the ball towards the center circle the other players can be cautioned if they are deemed dangerous-playing. The player will receive a caution and have to be withdrawn from the game.
Kicking the Ball When Your Team is Ahead: A foul can be given out if a player kicks the ball while the opponents are behind the goal line or in their own goal. This can also be done from behind the goal line.
Fouls are given out based on the severity of the offence and can be divided into two categories; fouls and cards. A foul is a rule violation, while a card is given out as a penalty to the player for repeated fouls or when the game has been stopped due to foul play.
Foul-Kicking: A player who cannot control his stick while kicking the ball can receive a card for foul-kicking. This can be done from behind the goal line, or from above the halfway line. It is also possible for a goalkeeper to be sent off during a match for this reason.
Dangerous-Playing: If a player starts to dribble the ball towards the center of the field, the opposing player can be cautioned. If a player is spotted to be in an offside position he can be sent off for dangerous-playing. This will result in a player being replaced and a penalty awarded to the other team.
If a player receives a card, he can receive more than one card. The first card will result in a red card for violent conduct while the second card can result in a yellow card, a warning card, a red card, or a suspension.
A yellow card will result in a player not being allowed to take part in any further play and another will be given out to the same player at the beginning of the next match. A yellow card is also suspended for a certain amount of time, so the player must wait until it has been served before he can join in any more play.
The second card is generally given out for simulation, which is the second most serious violation in terms of foul play. simulation can occur when a player is seen to deliberately try to lose the ball by pushing or kicking the opposing player.
