Jurgen Klopp said Villarreal can expect a much tougher time when facing Liverpool at Anfield ahead of Thursday's Europa League semi-final second-leg clash.
The Reds fell to a 1-0 defeat at El Madrigal in the first leg last week, but their boss expects the support of their fans to spur his players to give a much better account of themselves.
Klopp insists the club are undeterred in the challenge despite conceding Adrian Lopez's stoppage-time winner, claiming his men still have every chance of making the final.
"They [Villarreal] scored a goal in the last minute so if they hadn't celebrated something would have been really wrong," the German told reporters before the match.
"The only thing I thought in this moment was 'half-time'. Nothing happened. They have to come to Anfield.
"I am still feeling this, so the feeling is we are halfway through and I know how difficult it is. I sense the chance more than I am afraid of something - so let's try."
A win at Anfield would be the second time in as many Europa League ties that Liverpool have come from behind to win in front of their home fans after they edged Klopp's former club Borussia Dortmund in the quarter-finals.
And Klopp revealed he was in awe of the atmosphere genereated by the club faithful, adding: "I don't have enough words for this.
"It's one of the things in life you cannot buy. Feelings things like this are special. These moments when you really know we are all together.
"It's not only the crowd in the stadium. I saw a few videos of our fans celebrating our fourth goal [against Dortmund].
"I don't want to make it too big. It's only football, I know. But it's a moment for the whole Liverpool world and fans around the world. Everyone will watch it."
