One person on the left side of the pitch (can also be another position) and this person has to shoot as many balls at the goal as possible within 1 minute (or longer).
The rest of the players collect balls and one of them plays the balls to the ball.
Shooting the link-up in succession.
Keep track of how many times the player has scored.
When you have shot, you must walk backwards to your position. Keep changing until everyone has been there.
Variation:
Different ways of approaching (i.e. slightly inwards or outwards etc.)
Different shots (underhand throw, bend throw, out of the way, etc.)
