One of the most outstanding and influential players in the early years of the American Soccer League, Brittan came to the United States from the London club Chelsea. There he had shown a great deal of potential that was never realised, and after his career had been interrupted by illness, and the outbreak of World War One, he moved to the United States. At first he played for Bethlehem Steel and then in the first year of the ASL led a Bethlehem/Philadelphia combination, playing as Philadelphia, to the championship. In that season Brittan led the league in scoring with 24 goals in 17 games. After that one season Brittan's potential as a leader was quickly recognised by the new Fall River owner Sam Mark and before the start of the 1922-23 season Brittan signed for Fall River. With Brittan leading the attack the Marksmen won the ASL championship in the 1923-24, 1924-25 and 1925-26 seasons and in 1924 the Marksmen also won the U.S. Open Cup.
Played 17 American Soccer League game for Bethlehem Steel in 1921-1922.
Brittan was inducted into the Soccer Hall of Fame in 1951.
