North End were the original ‘Invincibles’ having gone through the Football League’s inaugural 22-game campaign in 1888-89 without tasting defeat. While they did it at a time when the game was still in its infancy, their record around that period was astounding. Preston won 42 successive games in 1887-88 and, during the following season, the ‘Invincibles’ also completed the double by winning the FA Cup without conceding a single goal.
