Barcelona striker Luis Suarez has said his team do not have to "go crazy" as they attempt to turn around a 4-0 Champions League deficit against Paris Saint-Germain on Wednesday.
Barca are looking to become the first team in Champions League history to overturn a four-goal margin from the first leg after they were thrashed at the Parc des Princes.
Some impressive recent results mean they go into the game at the Camp Nou believing they are capable of producing a comeback.
But Suarez, speaking at a news conference on Tuesday, warned: "The game will last 95 minutes and we must be patient. We have to be aware of that.
"Obviously we need to be ambitious, too, but not desperate. We don't need to go crazy in the first few minutes.
"No one wants to turn the tie around more than us, but we need to be calm. We want to go down in history."
A PSG goal could kill Barca's hopes of a comeback given that Luis Enrique's side failed to score an away goal in Paris.
But Suarez remained defiant and said: "A PSG goal could be decisive, but not necessarily -- it depends on the moment.
"We're aware of the quality they have but they know we're capable of doing a lot of damage with the ball."
Suarez said turning things around would provide "a spectacular show for the world," and said that if anyone could accomplish the feat, Barcelona could.
"It is difficult -- but nothing is impossible," he added.
"If there's a team that can score four, it's Barcelona. The beautiful thing about football is that every few days you have a chance to pick yourselves up."
Luis Enrique echoed the comments made by Suarez.
"Ask me after the game," he said. "It's not over until it's over."
