Have you ever wondered what would happen (in a penalty situation), if a goal keeper just held his ground, springing up and down on the spot, dead central and didn't dive to either his left or right?
Obviously, the player taking the penalty wouldn't know the keeper wasn't going to dive. A lot of players (allegedly) wait to see which way the keeper is going to dive before they place the ball in the opposite side of the net.
I wonder if a tactic like that would be enough to put the penalty taker off, and cause them to sky it or miss the goal completely?
