France’s Karim Benzema struck a hat-trick as Real Madrid hammered Barcelona 4-0 at Camp Nou to reach the Copa del Rey final on Wednesday, progressing 4-1 on aggregate.

Vinicius Junior opened the scoring just before the break as Carlo Ancelotti's side mounted a spectacular comeback from their one-goal semi-final first leg deficit, with Benzema adding a second-half treble, reports AFP.        

Los Blancos trail their arch-rivals by 12 points in La Liga and were beaten by Barca in the Spanish Super Cup final in January, but triumphed here to reach the Copa final for the first time since 2014, where they will face Osasuna.

"It was a complete game -- when you play a complete game, you win 4-0 like that," said Ancelotti.

Madrid turfed out the record 31-time cup winners with a muscular performance on a spiky night in Barcelona, where they also ended a demoralising run of three consecutive Clasico defeats.

Barcelona's Sergi Roberto said letting in Vinicius' goal on the stroke of half-time was a huge blow.

The Catalan said defeat would not damage Barcelona's title bid in the final weeks of the season.
