Lionel Messi was inspired as Barcelona beat Alaves to secure the Copa del Rey for the third year running and give coach Luis Enrique a winning send-off.
Enrique is leaving after three years in charge at the Nou Camp.
Ibai Gomez hit the post for Alaves before Messi scored his 54th goal of the season with a 20-yard curler.
Theo Hernandez bent in a free-kick to equalise, but Neymar turned in from close range and then Messi played in Paco Alcacer right on half-time.
