1. If the attacker attacks with the ball at the defensive half-court, the defensive player kicks the football into his own goal in the process, and the attacker scores.
2. If the attacker kicks a direct free kick, such as the goalkeeper's ball (usually caused by the opponent's foul), the ball kicks into his own goal, and the goal is valid, and the opponent scores.
3. If one player makes an indirect free kick, which is usually caused by the other player kicking the ball out of the baseline, and the goalkeeper kicks the ball into his own goal at the kick-off, then the goal is invalid.
4. If one side throws a foul ball directly into its own goal, the goal is invalid.
Extended data:
Generally speaking, the football that scores an own goal for the opponent is an own goal.
Score one point
The goal score is that the whole ball crosses the goal line from between the goalposts and under the crossbar, and it has not violated the rules of the game before.
Kick a free kick
Generally, when an offensive player is fouled by a defensive player, he will kick an indirect free kick where the foul occurs.
However, the attacker got an indirect free kick in the opponent's goal area and kicked it from the goal area line closest to the foul and parallel to the goal line.
