Any football fan will know goalkeepers play a unique role in their team.
But their brain may also function differently to outfield players, a study suggests.
Scientists present some of the 'first solid scientific evidence' that keepers show 'fundamental' differences in the way they perceive the world.
This may help them make quick decisions based on 'limited or incomplete sensory information', and possibly the difference between conceding goals and keeping a clean sheet.
Keepers noted for quick reaction times who may benefit from this include David Seaman, formerly of Arsenal and England, Brazil's Alisson Becker of Liverpool and Germany's Manuel Neuer of Bayern Munich.
