Las Palmas' third appearance in European competition came with the 1977–78 UEFA Cup, where they defeated FK Sloboda Tuzla of Yugoslavia in the first round before falling to the English side Ipswich Town. Under the management of Miguel Muñoz, and with players such as Argentines Miguel Ángel Brindisi, Daniel Carnevali (the first to arrive in 1973), Carlos Morete and Quique Wolff, the club also reached their first final of the Copa del Rey in that year, losing on 19 April to Barcelona at the Santiago Bernabéu Stadium (1–3).
