Manager Jurgen Klopp hopes Liverpool can carry the confidence from their 2-1 Premier League win over Aston Villa into Wednesday's Champions League quarter-final return against Real Madrid, where they will need to be "perfect."
Defender Trent Alexander-Arnold scored a stoppage-time winner as the champions fought back to beat Villa and end a dismal run of six league defeats at their Anfield home.
They have work to do to reach the semi-finals of Europe's elite club competition after losing 3-1 at Real in the first leg of their quarter-final last week, but Klopp backed his side to build on the performance against Villa.
"Whatever we can... we'll take. That's clear. We need a perfect performance on Wednesday if we want to have a chance only - just for a chance," Klopp said.
"I think the way we played and the way Real played there, it doesn't look promising but the good thing is we can play better. That would change the game already, but we have to. Real don't come here and think they're already through. It'll be a tough one, but we'll give it a try I can promise - and that's the only thing we can say."
Ollie Watkins fired the visitors ahead with a shot which squirmed through goalkeeper Alisson on 43 minutes.
Liverpool equalised when Mohamed Salah headed into an empty net after Emiliano Martinez parried Andy Robertson's cross, before Alexander-Arnold's late strike clinched the points.
