4 attacking players keep switching the ball (each transfer has to go via both link players).
Only one defender is only allowed to go out and defend when the attackers have received the ball.
If the attacking team switch the ball the defender has to pass the ball to the other defender who has to stop the ball before then being allowed to defend against the wing player.
The aim is for one of the wingers to dribble the ball through the grid on the side line and then cross the ball to the opposite winger coming in.
The defenders are only allowed to defend in the grid once the winger has entered the square on the wing.
The wingers have to receive the ball in their grid before they can run with the ball down the wing.
If they can get past the defenders grid without being challenged they can cross the ball to the opposite winger coming in to head the ball.
