Like Manchester City, the Reds boss Jurgen Klopp decided to make five changes to the starting lineup, and this reduced their usual attacking threat.
"The result is tough but we have 90 minutes and in football anything can happen".
City were eliminated last season in the last 16 by Monaco and it would be a disappointment for them to fail to make the last four after such a dominant season domestically. Pep Guardiola's side were at one stage holding a comfortable 2-0 lead, but they appeared to switch off in the second-half where United pounced with three goals in the space of 16 minutes.
"The most important thing for us is a clean sheet because if they score we have to score five". We need a strong mentality and we need goals.
"What we have done this season is fantastic and we have a chance to go through in the Champions League".
The Brazilian made the claim in City's press conference on Monday, with compatriot Danilo having accused Manchester United of the same at the weekend. "It could be missing chances but at the end of the day they scored three goals, we scored two and that's all that counts".
"Our fans will be together with us, and we are going to fight to the end". We all know about Pep, best coach in the world.
"But, if we are not able to cope with that psychologically, it will be a good lesson for the future". The way they play every single game shows what we want to do.
Greater Manchester Police will keep a firm eye on the tunnel and will immediately deploy extra officers to the scene should there be a build-up of City fans waiting for the Liverpool players.
"We've got a 3-0 advantage at half-time so it's down to us not to sit back and be on the front foot".
Manager Jurgen Klopp will issue an injury update when he faces the media at lunchtime.
