Defending Copa del Rey champions Barcelona became the first team to retain the trophy since 1998 as they defeated Sevilla 2-0 after extra time in the final.
Barca were the last team to clinch back-to-back Copa del Reys, which they did under Bobby Robson and Louis van Gaal's guidance, though they had to dig deep to make it a domestic double in 2016 having played for more than an hour with 10 men following Javier Mascherano's first-half dismissal.
The La Liga champions stood firm against the Europa League victors, who were back in action following Wednesday's win over Liverpool in Switzerland, and when Ever Banega's red card levelled up the numbers ahead of extra time, Barca had the staying power.
