Easy goals from halfway
When you start a match, change controls to the other team and hold [Keeper Rush] for the goalkeeper to rush out and get the ball. Pause game play while still holding [Keeper Rush] and change back to your side. The other goal keeper should keep rushing out and slide tacking you. Shoot from halfway and you should get a goal. Also for laughs, sometimes the goalkeeper grabs the ball meters from the box and nothing happens.
