Remember, a goalkeeper cannot pick up a backpass or they will give away an indirect free kick!
Tell your players they must NEVER pass the ball back to the goalkeeper between the goalposts.
ALWAYS pass to the side so that if the goalkeeper misses their kick, the worst that can happen is your team gives away a corner.
Make sure your players always pass to the goalkeeper’s strongest foot. A left footed goalie doesn’t want the ball on their right foot with an attacker charging at them.
This means you must let all your players know if your goalkeeper is right or left footed!
