Jordi Alba scored seven minutes into extra time and Neymar sealed the victory late to give Barcelona a bad-tempered 2-0 win over Sevilla for its second straight Copa del Rey title on Sunday.
After a 0-0 draw in regulation time, Alba found the net with a low left-footed shot into the far corner after a superb long pass into the area by Lionel Messi.
Neymar closed the scoring in injury time to give Barcelona its 28th Copa trophy.
Barcelona clinched its 24th Spanish league title last weekend.
Barcelona played with 10 men from the 36th after defender Javier Mascherano was sent off with a straight red card. The Catalan club also lost Luis Suarez with a second-half injury.
