This small sided drill is something that you will be able to do if you are fortunate to have some outfield players. It is a good drill when you have a full team as all positions will benefit from it.

The basic drill
1) Starting from GK2 (the bottom of your picture) they should pass to the red player who are trying to score into the goal defended by the yellows and GK1
2) When you pass it out to the wing and it is past the cones the defending team is not able to tackle the winger. The wingers job is to either deliver a cross for the attackers to try and score or cut inside the cones to create a 3 on 2 scenario
3) Once the ball goes out of play or the keeper saves it the drill is then repeated and it is now the reds turn to defend
What is it helping?
This drill primarily replicates having a shot against you however given you are organising your defence it should improve your communication skills. If the ball is crossed in instead of a shot taken then coming for the cross will benefit your handling.

Make the drill harder
– Having one more attacker than defender means that the attackers are more likely to get a shot away and therefore test the keeper.
