Easy Goals
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.

When you get a corner kick, aim it to the teammate nearest to the goal post (For example, a right corner, the person on the right goal post), then press [Maximum Pass] to him. When the ball gets to him, aim the shot pressing [Up] or [Down] then press [Shoot]. You will get an easy goal from the corner every time. The shooter must have a shot and accuracy ability that is high; the person should play on the right midfield when you are playing 4-4-3 (For example, use Zidane - Real Madrid).
