Barca have not won the competition since 2015 but finished second in the group stage and are among the favourites to lift the trophy.
Benfica have reached the final on seven occasions but have only lifted the trophy twice – in 1961 and 1962.
Barcelona coach Hansi Flick dismissed claims that his team have an “easy” path to the Champions League final, ahead of their last 16 clash against Benfica.
Should the Spanish giants progress from the tie, they will face either Borussia Dortmund or Lille in the quarterfinals.
Real Madrid, the record 15-time winners, as well as Atletico Madrid, Liverpool, Arsenal and Paris Saint-Germain are in the other half of the draw. Barcelona, who top the Spanish league by a point, could only meet those sides in a potential final.
“In this phase, there’s no easy game – every team deserves to be here at this stage, and I think Benfica too,” Flick told reporters on Tuesday. “Benfica is a fantastic team [and] we play in a great stadium and it’s really a special atmosphere there.
“Their [fans] push the team on a lot, supporting them, and it will be really tough tomorrow – hard work for us.”
Flick would not be drawn on who the tournament favourites are and which side would pose the most threat to Barca’s hopes.
“Always the next match. Benfica is for us the next difficult opponent,” the German coach said.
“It’s not good to [talk about] these things. We focus on the next match and the next match, and that’s a good way to do this.
“It always starts at 0-0, and you have to give everything… the other teams are doing really well and they always want to win against us.”
Barcelona beat Benfica 5-4 in Lisbon in a thrilling group-stage comeback.
Defender Pau Cubarsi said his team had to focus more to stop the Portuguese side, for whom Vangelis Pavlidis scored a 30-minute hat-trick.
“It was complicated… we gave up a lot of chances. We have to try not to concede goals,” said Cubarsi, who made his Barcelona debut in January 2024 and has rapidly become a key figure.
“We have to know how to manage games… this is a two-legged tie and we have to give everything from the start,” continued the 18-year-old.
“Each year, Barca should be competing for everything. For me, we are the best club in the world. This year, people say we have the best pathway in the tournament, but I don’t see it like that.”
