Instructions
Remove most of the Aurochs, the default team you play with, except for Wakka. He plays for no money and will never leave your team. There are better players, but because he plays for no money and is loyal, he is worth keeping. Find players with better stats, which is not hard.
Equip Nap Techs level two and three. Pass the ball around to all of your players. The other team will not be able to attack you. With 30 seconds left, go in for the score.
Use the invisible shot. You can score a goal every time if you aim slightly to the left of the goal while keeping out of the goalkeeper's circle.
