If you have an 90 or better rated player on your team, make them the corner kick taker. If you hold down the C button until the meter is fully red, the ball will spin in toward the middle of the box. Then, while the ball is in the middle of the box, set up for a header. Do this by taping the A button. Then the ball will be headed at the goal. Make sure that you aim the arrow directly at the goal. When taking the corner, you must aim the ball at the goal so it will spin back for the header.
