Set up field like diagram. Three blue attackers attempt to set up in the red half, trying to move the ball forward and score. Red defenders get compact and stay compact to prevent blue from building up and creating chances on their goal. Red pressure/cover/balance in attempt to win the ball back and work it wide, passing up the field through gates. After 30 seconds, coach may release extra player from either team to simulate midfielder getting back to help defense or midfielder coming up the field to help the attack.
