Barcelona coach Luiz Enrique and striker Luis Suarez have both expressed confidence that the Catalans are capable of overturning their 4-0 first leg loss against Paris Saint-Germain in Wednesday's second leg round 16 UEFA Champions League tie at the Camp Nou.
Both Enrique and Suarez spoke during Tuesday's pre-match press conference ahead of the clash.
Barcelona must create history by scoring five goals without conceding to qualify for the quarter-finals of this season's competition.
A brace from Angel Di Maria and a goal each from Julian Draxker and Edinson Cavani led PSG to a memorable first leg win over the 2015 champions.
Enrique, who will step down as Barcelona coach this summer, however called on fans who will be at the Camp Nou to make the stadium uncomfortable for PSG.
"We're in good form. We have to be optimistic, and we are," Enrique said.
"Camp Nou needs to be like a pressure cooker, ready to explode."
On his part, Suarez said: "A game that generates many expectations, a nice challenge for us.
"Difficult but not impossible. If any team can get four or more goals, it's Barça.
"We have the confidence, soul and enthusiasm to achieve a comeback. We will fight right to the end."
