Barcelona knocked out Athletic Bilbao after a 3-1 defeat at Camp Nou (on 4-3 aggregate). It’s a good thing for the Catalan club because in this situation, the Blaugranas have reached the finals ten times and meeting Real Madrid in four of those cases.
Barcelona can only hope the streak continues as they progress into a higher stage in the Copa del Rey competition. The first time Barca won the Cup back to back was from 1951 to 1953 after winning Real Sociedad, Valencia and Athletic Bilbao in three consecutive season.
Athletic Bilbao being the second most successful club in the Copa del Rey have encountered Barca before the finals and lost out. After that, Barcelona always find their way to the finals. This has happened on ten different seasons.
Both Barcelona and Athletic Bilbao have met in 24 seasons in 41 games (including finals).
