Final answer:
Keeper possession refers to when the goalkeeper has complete control of the ball in soccer. Charging into the keeper when he has possession is considered a foul.
Step-by-step explanation:
In soccer, the goalkeeper is the player designated to protect their team's goal. Keeper possession refers to the situation when the goalkeeper has complete control of the ball, usually by holding it in their hands or trapping it between their body and the ground. At this point, it is considered a foul for an opponent to charge into the keeper in an attempt to disrupt their possession.
For example, if the goalkeeper catches a high ball in the air or collects a loose ball rolling on the ground, they have gained possession. Once the keeper has established possession, opponents must give them space and cannot intentionally collide with them to try to snatch the ball.
However, it's important to note that there are certain situations where opponents may be allowed to challenge the goalkeeper, such as when the keeper drops the ball or when they release it from their hands and it is in play.
