2 cones are placed just behind the goal circle line with at distance of about 3 meters between them.
The CR is placed 1 meter in front of the goal circle and between the cones.
A defender is placed in front of CR, facing CR.
A helper is placed at the 9-meter line.

The CR must move from side to side with fast movements - and not be pressed into the goal area by the defender - and then quickly set in a screening.
When the screening is set the helper bounces the ball to CR and CR shoots/passes the ball to the goalkeeper.
The goalkeeper returns the ball to the helper and the exercise continues.
The defender must face CR all the time.
