While facing one or two other players, do an over the head beat. Before you catch the ball, pass it to a nearby teammate. In the middle of the pass, hold X to usually confuse the goalie and score. If you do not have any nearby teammates, just hold X when the ball is in the air to shoot.
Note: This trick requires the advanced move where you hold White + Black and press the Right Analog-stick Up/Right. To make an easy goal with this move, you must be near the goalie and running. Most angles work, but it is best to run at him straight on. When you are close enough, perform the advanced move. It will say that the move is blocked, and the goalie will rush to the floor. However, your player will already push it over the keeper's head and into the net. This usually works about 85% of the time and requires some practices.
Go to the "Game Modes" screen, then choose your team. Go to "Head Start" and set it as desired. For example, if you want to win by five goals then choose "Head Start 4+" so that you will only have to score one goal to win.
