But if the Reds need any inspiration ahead of Sunday, they need look no further than their performance for the first half-hour that day.
Incredibly, Pep Guardiola's side have dropped just four points all season, and their quality of football has been admirable. The French worldwide joined United in 2006 from Monaco for £5.5 million, and despite having a nightmare on his debut against Liverpool he would go onto become one of Sir Alex Ferguson's most trusted lieutenants.
"Spain made a big step forward with the national team and the clubs 10 years ago when the journalists talked about what happened before and after the game on the pitch", he said, in an observation that was later challenged by a member of the Spanish press corps in Manchester.
While Moreno himself was experiencing a rich vein of form before his unlucky injury, it wouldn't make sense for Andy Robertson to make way for the Spaniard given that he has been in superb knick in the last month, helping the Reds win some crucial games.
"He [Klopp] is letting Emre Can go at the end of the season. The records are there to be broken".
Liverpool defender Virgil van Dijk admits he is flattered by his world-record £75m price tag but insists that does not mean he will stop working for his place in the team. Liverpool's energetic play and pressing could be enough to topple City, who themselves have struggled against the press in recent weeks.
Van Dijk views £75m price tag as 'a big compliment'
Across all competitions, Liverpool are actually on a better run than Manchester City in the last 17 games. That is our target, and to show courage. "You have to win these kind of games".
This Newcastle side are vulnerable at home and the longer a game goes on the more likely they are to concede.
"If you can get in between the lines and at the two (City) centre halves, which I feel we can, then there are chances and goals there".
"Gabriel was in Barcelona yesterday with Dr Cugat".
If we continue on anywhere close to the current trajectory, the league will be all but wrapped up sooner rather than later, affording Guardiola the golden opportunity to rest key players before the semis and quarters of the Champions League.
