Svend Aage Castella (15 March 1890 in Copenhagen – 28 November 1938 in Copenhagen) was a Danish amateur football (soccer) player, who played for 13 games and scored one goal for the Denmark national football team.[1]
Castella played his entire career with Copenhagen club KB, with whom he won several Danish football championships. He made his Danish national team debut in October 1911, and was a part of the Danish team at the 1912 Summer Olympics. He was an unused reserve player for the duration of the games, and was not awarded with a medal, as Denmark won silver medals in the 1912 football tournament.[2]
