Liverpool captain Jordan Henderson insists his team are not worried by what Manchester United will throw at them at Old Trafford.
Jurgen Klopp's side take a 2-0 lead into the second leg of their Europa League last-16 clash having completely dominated their arch-rivals a week ago at Anfield.
Only the brilliance of United goalkeeper David de Gea kept the tie alive for United and Henderson believes a similar display from the visitors will be enough to book a quarter-final spot.
"We've got to prepare on what we want to do, focus on our game plan," he said.
"If we do that, it won't matter what Manchester United do. It's all about us. I don't think we can worry too much about what United do.
"Our main focus is on what we can do; energy levels, playing high-intensity football."
The comprehensive nature of last week's victory, the first United boss Louis van Gaal has suffered against Liverpool in his five matches against them since arriving in England, has boosted morale levels.
It was a win that suggests the players are starting to get to grips with what Klopp has been asking of them since taking over at Anfield in October.
However, Liverpool have to guard against complacency despite their advantage.
"It was a good night. Not only the result but the performance so we can take a lot of confidence from that," added Henderson.
"I think the last few weeks we have been building momentum. But it's only halfway. Hopefully we can finish the job off."
Meanwhile, Liverpool boss Klopp (above, left) has questioned the consistency of UEFA's disciplinary procedures after Marouane Fellaini was cleared of elbowing Emre Can.

The United midfielder clashed with the Germany international in the closing seconds of last week's 2-0 victory at Anfield.
Fellaini appeared to catch Can with an elbow to the face but the incident was missed by Spanish referee Carlos Velasco Carballo.
It was not mentioned by match officials in their report so there was no retrospective action from European football's governing body.
Klopp said he did not have an issue with that, but pointed out he was banned for one game in 2013 after being sent off in Borussia Dortmund's Champions League match in Naples.
UEFA's disciplinary committee subsequently increased the punishment to two matches.
"Surprised? No," said Klopp when asked what he thought of Fellaini's availability for Thursday's return leg at Old Trafford.
"What can I say? It was a situation with different views at the end. A lot of people at UEFA watched it and said it was a normal challenge.
"That is no problem. They gave me two games for my face in Naples."
