After struggling to beat Intercity in the last round of the Copa del Rey, Barcelona will again face third-tier opposition.
Barcelona will face the lowest-ranked team left in the Copa del Rey after being drawn with Ceuta in the last 16.
Xavi's side will be huge favourites to reach the quarter-finals, with their next opponents propping up Group 1 of the Primera Division RFEF, Spain's third tier.
Nevertheless, Ceuta – who beat LaLiga's Elche in the round of 32 – will take encouragement from Barca's struggles in the last round ahead of welcoming the Catalans to Africa's north coast.
Ansu Fati's extra-time goal made it 4-3 and eventually sealed Barca's passage, but it was still alarmingly close to an upset for the Blaugrana.
