Villarreal v Liverpool: Jurgen Klopp warns Reds to be wary of a backlash in Champions League semi-final

Despite a two-goal advantage, the Reds will have to be ready to suffer in the second leg.

They will go for us, so we have to be ready to play a top game.

The Reds have won European titles six times.

They will try to play more football than we did in the first game.

We have to be ready to suffer and my only concern is what we do. In football matches, it is possible to go 0-1 down or whatever, but to give the game the right direction.

If they have the first shot on target, the crowd goes up, each challenge, the crowd goes up and that is how it is.

• Go straight to all the best Liverpool content

In addition to Origi, centre-back Ibrahima Konate, Thiago Alcantara and Fabinho, and forward Mohamed Salah are all expected to feature after being rested.

Roberto Firmino will not travel with the squad to Spain because of a foot injury.

The Reds have already won the Carabao Cup, played in the FA Cup final and are one point behind Manchester City in the league.

Since the turn of the year, the side have lost only three times and been behind for only 69 minutes.

With all these things during the season, we must have done something right, said the German.

The problem in our job is that everything is perfect until the next game starts on the wrong foot.

'We need to play a perfect game' - Emery

After beating Manchester United in last season's Europa League final, Unai Emery's team qualified for the European Championship and have eliminated both Juventus and Bayern Munich on their way to the last four.

With four league matches remaining, the Spanish side are only seventh in La Liga, nine points adrift of fourth-spotted Atleti Madrid in the final European spot.

If they don't win the title this season, it's very likely that they won't play in the competition in 2022-23.

Emery admitted on Monday that they need to play a perfect game.

We need to find our excellence in certain things and maybe achieve something no-one has achieved, which is this kind of comeback.

We will try to find some weak spots, something that no-one has done this season.
