What exactly is a cultured left foot? Why are goalkeepers afraid of penalties when no-one expects them to be saved? Did Frank Haffey receive treatment for post-traumatic stress syndrome after letting in nine against England in 1963? Is a winter spectating at Pittodrie the best training for an Antarctic expedition?

In an attempt to get to the bottom of them, Alan Taylor, literary editor at "Scotland on Sunday", has commissioned essays from some of Scotland's finest scribes, including Barry Graham, Brian McCabe and Alistair Reid.
