The European champions visit Anfield with a 2-0 aggregate lead for the second-leg of their quarterfinal.
Enrique said on Monday afternoon: . "It was only the first match. When you play this competition away against a team like Liverpool, there is only a two-goal lead. It will be difficult.
"There will be times of difficulty. That's the difficulty. It's a trap match. We believe we are superior, but sometimes that can change very quickly in football. You can concede a goal in the first half and that's another game. The key is to prepare for all matches in the same way. I have to prepare my players for difficulties.
"We seek to prepare for the match in the same way, regardless of the result. We are always looking to win. Trap match? We always seek to balance. This is a very tight result from what we have seen. You have to be ready for every moment of difficulty and there will be several.
"All the players are motivated.You have to find the perfect motivation. I'm sure we'll be ready. But we will suffer..."
