He also managed Olympique de Marseille for six seasons and earned eight caps with the Hungary national team.

In June 1926, Nat Agar, owner of the American Soccer League’s Brooklyn Wanderers, signed Eisenhoffer.

[5] In 1928, the ASL initiated a struggle with the United States Soccer Federation for control of football in the U.S.

This conflict, known as the "Soccer War" led to the USFA declaring the ASL an "outlaw league".

When that happened, Eisenhoffer had already played eight games in the 1928–1929 season, but then jumped to the New York Hakoah of the fully recognized Eastern Professional Soccer League.

New York Hakoah won the 1929 National Challenge Cup with Eisenhoffer scoring one goal in the first leg victory over St. Louis Madison Kennel.

[citation needed] Eisenhoffer left the U.S. and returned to Austria where he signed with Hakoah Vienna.
