Jurgen Klopp says Liverpool need to be braced for a ‘thunderstorm’ from Manchester City.
A place in the Champions League semi-final remains in the Reds’ hands after a 3-0 win over Pep Guardiola’s side in last week’s first leg.
Klopp also saw his players surrender a similar margin in the space of 45 minutes earlier in the competition when they were held to a draw by Sevilla.
And the Liverpool manager insists that November’s group stage encounter should forearm his players for a potential onslaught at the Etihad Stadium.
He said: “I don’t need to remind the players of a specific game.
“But I saw the game of City v United at the weekend. It was one of the best first halves I ever saw. It was like a thunderstorm.
“Then, in the second half, they change the game. After the first [United] goal, one team gains rhythm, another team loses rhythm.
“We can go through all scenarios – they score early, we score early, all that stuff – but it is not to plan like this. I can tell the boys ‘Score early!’
“But I’m not sure that really helps. We have to think about football – what we have to do, where we have to do it. This is half-time.
“It was the same at half-time in Anfield: the game is not over. We were in the lead, nothing else. Being in the lead is not winning.
“We are still in the lead but we didn’t win so far. We need a little bit more from this game.”
