The Hungarian Izidor Kürschner-Szűcs, usually known as Dori Kürschner (or Dori Kruschner in Brazil) was one of the coaches who contributed to the evolution of the modern game in quite a subtle way. Even though he died in 1941, his greatest contribution to football probably came after 1937. As coach of Flamengo he changed the way Brazilians thought about tactics and formations, setting the stage for later triumphs.Kürschner played for MTK Budapest from 1904–1913. This was a succesful period for the club, who were coached by Jimmy Hogan from 1914.
MTK won the Hungarian League in 1904 and 1907–08, and the cup 3 seasons in a row (1910-12).
A left half or centre half, Kürschner made his international debut for Hungary in 1907. He won 5 caps over the next 4 years, never being a regular . Kürschner commenced his coaching career in 1918 with MTK.

1924 Switzerland (National team)
Switzerland were coached by a Technical Commission made up of 3 members, each representing one of the regions of Switzerland (east, central and west).
