• Barcelona have been in the round of 16 every year from 2004/05 onwards, winning 13 of those 15 ties. They lost two of the first three ties, most recently against Liverpool in 2006/07, but have won their last 12 – recording a home victory in all 12 ties. They have never lost a round of 16 tie when playing the second leg at home.

• Both those previous last-16 ties ended in defeat against the eventual winners; Real Madrid beat Napoli 3-1 home and away in 2016/17, five years after Chelsea turned round a 3-1 first-leg defeat in Naples with a 4-1 extra-time success in the return.
