Place a collection of balls in a corner.
The players, each with one ball, form a line at the centre of the court facing the goalkeeper.
The goalkeeper runs down to the corner, picks up a ball, passes it to the first player in the line and runs back
to the goal. The player receives the ball and shoots when the goalkeeper has reached the crease.

Versions:

• Place a ball collection in the other corner too and let the goalkeeper pick each corner every other time.
