The 1970s represented a decade of highs and lows for Real Betis. League form varied wildly and the club spent the period alternating back and forth between the top two divisions. The highlight was the successful Copa del Rey campaign in 1977? Its foundation laid in the first game by coach Ferenc Szusza, who led the club from 1971 until 1976, and finished under coach Rafael Iriondo. This successful cup campaign would mark the club's first win in the competition and its first major honour since 1935. The resultant European campaign brought a famous opening round win over Milan.

This was also a decade that saw Betis legends made with many of the most loyal and longest-serving players in the club's history making their debuts, including Francisco Bizcocho, Jose Ramon Esnaola, Antonio Biosca, Julio Cardenosa and the great Rafael Gordillo.
