Barcelona manager Quique Setien has admitted his side remain haunted by the manner of their Champions League exits in the past two seasons.
La Blaugrana suffered a 3-0 defeat at the hands of Roma in 2017-18 after taking a 4-1 lead into the second leg, with Kostas Manolas's header seeing Barca bow out on away goals.
Last season saw the Catalan giants exit in similar circumstances after Liverpool produced a storming comeback from a 3-0 first-leg defeat to win 4-0 at Anfield, with Jurgen Klopp's side eventually going on to win the competition.
Looking ahead to the first leg of their last-16 tie with Napoli, Setien acknowledged that these defeats still linger in the minds of his players.
"The reality is that we've spoken very little about [the Roma and Liverpool defeats], although I'm sure they'll have it in their minds," Setien told reporters.
"Maybe it's not comparable. We've experienced incredibly tough games and I think the team is fine. The team is confident that we'll continue in this dynamic, I trust that we'll maintain the level that we've been giving for some time."
Barcelona's 5-0 drubbing of Eibar at the weekend saw them overtake Real Madrid at the top of La Liga, with Lionel Messi scoring four of Barca's five goals.
