Campbell did put up a decent fight for the number 1 jersey, playing in all but four games of the 1913–14 campaign, and he was between the sticks for the 1914 FA Cup Final at the Crystal Palace ground on 25 April. The game finished disappointingly for Liverpool, in a 1–0 defeat to Burnley. The match was to be the last to be played at this venue and it was played in front of a reigning monarch for the very first time, George V. Like many footballers of his era, Campbell's career was interrupted for four years due to the First World War, however upon his return to the game in 1919 he found himself once again number 1 for Liverpool. He stayed there until April 1920, when he played what turned out to be his last game for the club.
