A kickoff is the method of starting a football game or restarting it after a goal is scored. It is taken at the center part of the soccer field. During a kickoff, both teams must be on their own halves and only the kicker and the receiver can be inside the center circle (the big circle on the middle of the soccer field).
Rule 8 of the FIFA Laws of the Game determines the start and restart of play. According to the highest governing body of football, a kickoff restarts a play:
Before the start of a soccer game, the referee tosses a coin. The team that wins the coin toss is given the privilege to take the kickoff or choose their half of the field. If they choose which half they play, the other team will kick off and vice versa. The team that did not kick off will do so at the beginning of the second half. After a goal, the kickoff is given to the team that has been scored against.
Players should follow a set of rules when they kick start a match. Below is the procedure:
Yes, a player may attempt to score a goal after the ball is touched by the kicker. (See video)
An indirect free-kick is given to the opposing team if the kicker touches the ball twice before it is played by another player.
The kickoff has to be repeated for any other infringement of the kickoff rule.
