How to take a penalty kick

A scientist who has analysed memorable World Cup games over the past 50 years has discovered that the trick to scoring a penalty in this year's World Cup is to aim for the top corner. From Reuters:

Using biomechanics to calculate the absolute reach of a goalkeeper diving to try to save a penalty, Bray has identified an area near the posts and in the top corners where the goalkeeper cannot reach as the "unsaveable zone".

"If a player were to place the ball in those regions which are 28-30 percent of the goal area there is not a sniff that the goalkeeper can do to get across to them," explained Bray, from the University of Bath in England.
