I had goalkeeping trials for Brighton and Southampton, did ok and would have been offered a place if I had not had a motorcycle accident and broken my leg !
Couldn't heal them in 6 weeks in those days, anyway I'm only 6ft.
My figure came from a page called 'the shortest goalkeepers in football', there were a couple at 5 ft 8 ins on it as well, never heard of them but one played for PSG.
