The role of the goalkeeper in football is uniquely specialised and typically players develop as keepers at a later age. In the youngest age groups, keepers can be uninvolved in the game for long periods, which can be uninteresting and means they are not part of the team for long periods of the game. The role of the goalkeeper has changed in the modern game, they need to be capable to act in the game as “sweeper” who can kick a ball, control a ball and build up the game without using their hands. Most goalkeepers have played for many years as field players before deciding to become goalkeepers.
