Juan Gualberto Casco Bogarín (born 12 July 1945) is a Paraguayan retired footballer who played as a midfielder, primarily in Spain.
Casco, who was described by Mundo Deportivo as quick and incisive in his play,[1] spent five seasons in La Liga with Elche, scoring 25 goals in 97 official matches for the club.[2] Casco scored twelve of the goals in the Copa del Rey, making him the club's third-highest scorer in that competition. He scored the deciding goal against Real Sociedad in the 1969 Copa del Generalísimo semi-final playoff,[3] leading the club to the final – its highest profile moment.[4] Casco played in the final, but was unable to prevent Athletic Bilbao from winning 1–0.[5]
