To easily win without trying, pass the ball to the goalie by running into him, then pass the ball to another teammate close by. Then, give back the ball to the goalie once again. He should pick up the ball constantly whenever you keep this up. Do a regular pass or a lob pass when you are about to get hit by something, or simply run out of the way if you are going to be tackled. Wait until the time runs out and you should have won the match without engaging in any difficult field battles. Note: You must score at least one goal first for this trick to work. Also, if your CPU opponent has a power-up item, you can waste it by staying near to the goalie's end of the field while just simply waiting until the CPU attacks you with it. For maximum effectiveness, play only a two minute game, or you can use cheats such as turning off power-up items, Bowser attacks, and not allowing Super-Strike goals. The CPU's difficulty level also plays another major role.
