Arthur was a forward who made over 50 League appearances for Liverpool just before the First World War. He had a good goals-per-game ratio and was the club's highest scorer in the 1912-13 season, when he netted 15 times from 28 matches.
He also scored a hat-trick in the F.A. cup that year with three of Liverpool's four goals in a fine 2nd round victory away to Arsenal. But he neither played nor scored as regularly the following season, just two goals from 10 games.
Despite the outbreak of war, the 1914-15 League season was completed and Metcalf added another 7 goals to his career total. Although he never played competitive League football for Liverpool again, Arthur was a prolific scorer for the club in the local Lancashire leagues that were arranged to replace the national divisions.
