Never Lose
When playing the game, and the other team is ahead, pause the game and go to controller select, and select the other team. Then continue the game only when you get the ball score in your (the other teams goal the one you want to lose.) net. Then when your real team has enough goals to win, switch back to your team. But make sure you switch back to your team before the time runs out (you will lose.).
