My advice is to follow the player until he pauses to kick, and then shoot. Trying to follow the ball is actually harder. Follow the player. Another pointer is to stay behind the goal area, because the action will often be coming toward you. Shhoting from the touch line is a little harder, but I have some good shots from there too. (I'm assuming manual focus here.) __________________________________________________ Do You Yahoo!? Send instant messages & get email alerts with Yahoo! Messenger. http://im.yahoo.com/
