2 or more balls
6 or more players

Setup:
2 players in each corner of the goal line.
2 players at the top of the penalty area.

Player 1 will pass to the player at the top and goes to the other side of the field to defend player 3 who receives the ball from the top.

From here the play is 1 on 1.

Put the emphasis on the defense of the defender.

Defender goes to the top of the penalty area.
Offense becomes defense.
And the passer goes to the other corner.
