Due to several time-wasting techniques which were used by goalkeepers, such as bouncing the ball on the ground or throwing it in the air and then catching it again, in the 1960s, the Laws of the game were revised further, and the goalkeeper was given a maximum of four steps to travel while holding, bouncing or throwing the ball in the air and catching it again, without having to release it into play. The FIFA Board later also devised an anti-parrying rule, saying that such deliberate parrying for the purpose of evading the Law was to be regarded also as holding the ball.
