In total, he made 65 appearances and scored 31 goals for the national team.

His specialty was corner kicks; gaining a reputation for often trying (and succeeding) to convert them directly.

Others touted him as "the best non-professional player in Europe" (professionalism was not allowed in Germany in the 1930s).
