Collective replacement and management of offensive and defensive space

On a half-field, set up 2 small goals with cones on each side of the center circle. Place 5 attackers and 4 defenders with a goalkeeper.

The attackers must try to score in the large goal and the defenders in the small goals. The defenders must make at least 3 passes before they can score. The attackers must play quickly, with a maximum of 2 touches. 

Change players every 3 minutes.

Explain clearly to the defense the defensive transition when losing the ball: the defender closest to the ball will press the attacker while the others track back into their zone or mark one of the attackers.
