Attacking Strategy
Generally, you want to spread out on offense and become a compact unit on defense. On offense, use the entire field to break up the defense, creating gaps and spaces to attack.
The best way to open up spaces in the opposing team’s defense is to keep the ball moving. Let the ball do the work. Play it into the forward’s feet, and then have him or her lay the ball off to someone making a run through towards the goal or, if the forward is covered, lay it back to the midfielder, who plays the ball wide. The wide midfielder then tries to get a cross in, or switches the ball back to the other side where there is more space.
Your strategy, when you play the ball to the forward who is tightly marked, is to draw the defense into this player. Once the forward gets a touch on the ball and holds the ball up with a touch or two, the midfielder can get the ball back and pass to another player who’s now open, since the defense has collapsed around (or at least shifted their focus on) the forward. The pass can then be made behind the defense to get them chasing the ball with their heads turned.
