Bypass opposing players:
Pause game play, go to the options menu and choose "Side Select". Switch to the opposing team and resume game play. Get the ball with a defender or attacker, then hold R1 and shield it. Keep R1 held, and pause game play. Go to "Side Select" and switch back to your original team. Whenever that player gets the ball, he will shield it, allowing you to pass him and score.

Hint: Easy goals:
When you get the ball, try and get past the defenders by sprinting (tapping Triangle). When the goalie is going up to you, press X and the ball will bounce back off the goalie, allowing you to easily score a goal.

Glitch: 7 on 7 game:
Enter the training part of the game and set all the settings as desired. Go to "Training Game" and select "Offense". Now it will be a 7 on 7 game. You can remove the disc from the PlayStation2 and the game will still run, but without music.

Glitch: USA chants:
You can hear the voice of the fans and audience shouting "USA" "USA" "USA", in any league or match whatsoever even those that do not concern the USA.
