For years Oxford United and Accrington Stanley were two clubs, inextricably linked by history, who had never played each other. Of course, all that changed last season when Accrington visited the Kassam Stadium to play out a 0-0 draw in League Two (neither side has ever scored against the other yet). On Saturday, Accrington make their second visit and now seems as good a time as any to revisit the circumstances in which the two clubs came to be joined in the history books.
