[4] His first La Liga match occurred on 29 September 1974 in a 3–0 away loss against Valencia CF and, in the 1976–77 season, as the Lions reached the final of the UEFA Cup and the Copa del Rey,[5] also finishing third in the league, he totalled 29 goals in 46 official games; in the latter competition, over a 12-year stint at the San Mamés Stadium, he reached the 20-goal mark twice.

[4] Dani helped Athletic to back-to-back titles in his later years (1983–84),[3] although he was only a fringe player in the latter campaign – ten matches, three goals – due to the emergence of another youth product of the club, Manuel Sarabia.

He would be further pushed down the pecking order after the first-team promotion of Julio Salinas, and eventually retired in June 1986 at the age of 35, having scored 147 league goals from 302 appearances.

[4] Dani's total of 11 goals in European competition stood as a club record for 25 years, until passed by Fernando Llorente in 2012.

[8] Dani represented his country at both the 1978 FIFA World Cup and UEFA Euro 1980, respectively scoring against Austria and England (2–1 defeats and group-stage exit in both cases).
