In the past Preston was famously successful, being the first winner of "The Double" in English football. In 1888/-89 Preston became the only team to go throughout an entire season unbeaten in both the league and FA cup – also with the record of never conceding a goal in the FA Cup. Arsenal, in 2003/-04, also managed to have an unbeaten season in the top flight (although Arsenal played 38 games to Preston's 22) but went out of the FA Cup at the semi-final stage. Wikipedia
