Setup. A 10 by 10 metre square of cones. Passers stand on the sides, one defender in the middle. Feet only, no gloves.
How it runs. Passers keep the ball away from the defender with two touches. A pass that splits the defender is worth two. If the defender wins it or it leaves the square, whoever lost it swaps into the middle. First to ten passes wins the round.
Make it harder. One touch when it is on. Then make the square smaller. Then every third pass must be with the weaker foot.
With 4 keepers. Three passers and one defender.
