Liverpool boss Jurgen Klopp said Manchester City's back-to-back defeats showed they are "human beings" but acknowledged his side will have to be "at our best again", despite holding a 3-0 advantage from their Champions League first leg victory at Anfield.
"We are not thinking about who is favourite," he said.
"It is better than I expected but you all know there is still a lot of work to do."
City thumped Liverpool 5-0 in their Premier League match at Etihad Stadium on 9 September.
Referencing that game, Klopp said: "The quality of City was clear.
"We all know about Pep - best coach in the world. It was clear they would be outstanding but there is no perfect football team in the world.
"They have it most consistently, that is why they will be champions, but we know they can concede goals."
