Liverpool boss Jurgen Klopp has declared Manchester City the "best team in Europe".
Liverpool host City on Sunday.
"This is a really special game every year and you have to be your best version, and only then, you have a chance," he said.
"We have to play a proper football game to have a chance but it's Anfield. We are really looking forward to it.
"They [City] are probably the best team in Europe at the moment. Last weekend they played Chelsea and everyone was talking about how good they are, which they are, but City were clearly better that day.
"We have to win the game and score goals but we have to defend at the absolute highest level to stay in the game and make sure the goals we score make the difference."
Klopp added: "They lost against Paris-Saint Germain and straight after the game I said they will probably strike back. But they don't have to as I have since watched the game and they played a really good game.
"They didn't use their chances and PSG scored, but when you think of PSG's quality and the way Man City dominated them, it tells you a lot about their quality."
