Luis Enrique believes if Paris Saint-Germain can score four against Barcelona, “we can score six times against them” ahead of the second leg.
Trailing 4-0 from the first leg at the Parc des Princes, the Barca boss believes his side have the capabilities of mounting a remarkable comeback win in the tie.
"There are 95 minutes left and lots of things can happen,” Enrique told his pre-game press conference.
“I go into the game with a positive mood. We have to do everything really well, both in defence and in attack. PSG are a really good side.
"Of course, lots of things have happened since the first leg. We have improved and have put in some good performances. We are optimistic by nature and convinced of what we can do.
"If a team can score four times against us, we can score six times against them. We have seen that before this season.
"My optimism does not mean I have unbreakable faith. We have not been in a situation like this before, but I have faith in the team.”
