Gain possession of the ball
When your opponent's goalie has the ball in his or her hands, stand in front of it and press the "kicking" ball button (either the Left Mouse Button, [Shift], or [Ctrl]) rapidly. If done correctly, you should have headed the ball into your control. Note: When goalie spins around to avoid you, follow the ball.
