Liverpool captain Virgil van Dijk is expecting an even tougher test from Paris St Germain at Anfield than in the Parc des Princes last week.
On Wednesday they were dominated by the Ligue 1 champions in a way rarely, if ever, seen in recent seasons and were fortunate to snatch a 1-0 victory late on in their Champions League last-16 first leg.
Luis Enrique's side arrive on Merseyside knowing they have to score to stand a chance of progressing and Van Dijk believes that could make them even more dangerous.
"I think they are an outstanding team, a fantastic team, you can see the work rate they put in," he said.
"We obviously had a debrief after the game about it and you could see them, if they lost the ball, pressing all of them together and running all together.
"It's a big credit to the manager to put that work in and he made, in my eyes, a world-class team out of it.
"It will be tough on Tuesday and you will all see. I think anyone who before our game over there expected it to be a dominating performance from us I don't think they really looked at PSG throughout the season.
"We were prepared very well, obviously we could have done better in some ways, but we know that on Tuesday it is going to be as tough, maybe even tougher, because they will have to come and win.
"So it's down to us to be more than ready for a big night. We need everyone in that sense: all the players, staff, fans.
"Hopefully it will be a great night for us but it is going to be hard work because they are a world-class team and they showed it against us already."
Liverpool forward Diogo Jota has not scored a Champions League goal for more than three years and while he is keen to end that drought he insists he does not necessarily judge his contribution on goals alone.
It is an approach head coach Arne Slot has recently applied to fellow forward Darwin Nunez, although that did not excuse the Uruguay international a public admonishment when his work-rate dropped.
Jota, who has been plagued by injuries over the last few seasons, has only scored eight goals this season, with the last coming two months ago at Nottingham Forest.
His five career goals in the Champions League include a 2020 hat-trick against Atalanta so he has some improvement to do on that front.
"It's been a difficult season for me personally, I had a few complications throughout the season," he said ahead of the visit of PSG.
"These last couple of months matter the most when they decide things and I don’t feel I am at my best form at the moment but certainly by playing I will get there.
"Stats are a part of today’s game but they don’t say everything. I want to score, obviously, but that is not a factor which will impact my game tomorrow.
"If I don’t score but we go through I don’t mind a few more days into it (his Champions League drought).
"As long as you keep being useful to the team that is the most important. Sometimes it is not only the stats but the way you can connect with your team-mates and help defensively and in the end help the team get the win.
"That’s what I try to do every time I’m on the pitch."
