Barcelona sailed comfortably into the Copa del Rey quarter-finals thanks to a second-half splurge of goals in Thursday's 5-0 win over third-tier Ceuta.
The Blaugrana started slow at Estadio Alfonso Murube, but ultimately had few issues in sealing a place in the last eight.
Robert Lewandowski scored twice in the second half, either side of goals from Ansu Fati and Franck Kessie, to ensure Barca's progression was routine enough, with Raphinha having put the visitors ahead before the interval.
LaLiga leaders Barca are well in the hunt for a domestic clean sweep after their Supercopa de Espana victory over Real Madrid.
Despite naming a side littered with top-tier talent, Barca did not impose themselves as well as might have been expected throughout the first half.
The visitors struggled for clear-cut opportunities despite posting an overwhelming 69.8 per cent possession figure.
It was a piece of individual brilliance that unlocked their hosts four minutes before half-time, when Raphinha curled beyond Tomas Mejias.
Barca doubled their lead five minutes after the break, when Kessie picked off a wayward pass deep in Ceuta territory to set Lewandowski up for an easy finish.
Fati capped a fine solo run with a deft touch to put Barca 3-0 up, with Kessie turning from provider to scorer as he headed in from Raphinha's cross seven minutes later.
Lewandowski got his second in the 90th minute, drilling low into the corner to cap off an emphatic win after Kessie, Fati and Jordi Alba had gone close.
