Barcelona shrugged off Hercules 7-0 to win 8-1 on aggregate in their Copa del Rey round-of-32 tie on Wednesday at the Camp Nou.
Summer signing Paco Alcacer scored his maiden goal for the club, while Lucas Digne, Ivan Rakitic, Rafinha and a Arda Turan hat trick completed the rout of the overmatched Segunda B side.
And it was the French left-back who put Barca ahead in the 37th minute with a calm, poked finish after collecting a loose ball in the box.
Rakitic added Barca's second from the penalty spot on the stroke of half-time after Fernando Roman fouled Turan in the box.
And Barca poured it on after the break, with Rafinha and Turan scoring within the first 10 minutes of the reset.
Alcacer collected his long-awaited first goal in the 73rd, and Turan added two more strikes in the final five minutes to cap the easy win.
