i hate writing this its sounds so big headed
i shoot for the top corners and almost always score my penalties
even if the keeper guess's right it always goes in (ive missed a 4-5 from putting it wide or hitting the post
i got this from relentless practice, and also i curl the ball with the inside of my left foot, so most of the time it looks like a pretty sick penalty... with power and curl and accuracy
if i'm taking a second penalty against the same keeper i have a deception trick:
i set the ball down, take a good long look at the keeper and shape as if i'm gonna curl the ball to the left post, but instead i kinda clip the ball with the edge of my foot closest to the heel and the ball skids (pretty quick) into the right bottom corner.
works like a charm if you really shape your body to shoot in the left corner... but if the keeper gambles and dives the right way (you look like a plonker)
and if i'm taking a third:
i set the ball down, slowy track straight back a few steps STARING the keeper down, during my run up i never take my eyes off him even when i strike the ball (with my instep low for one of the corners) i never take my eyes off him. i sometimes even wait for the keeper to dive or shift his weight one way then put the ball in the other corner. you would be surpised how intimadated some keepers get, but it has to be well rehearsed so you don't scuff the shot. a handy little trick is to imprint your support foot-print beside the ball (so you don't even have to watch the ball
alot of people say 'don't shoot high'
they say this is because its alot easier for someone to put the ball off target completly when shooting high... like it doesn't matter which way the keeper dives if the ball goes over the bar... its logical but if you have confidence that you will score in the top corner then try it!
