Liverpool are 3-0 up on aggregate following the first-leg victory at Anfield last week as they eye a place in the semifinals of the Champions League for the first time since 2008.

However, Klopp said sitting back and hoping to see out the tie with City is not option due to the attacking strength of the Premier League leaders.

"We are here to not concede and to score to win the game. There is no other plan," Klopp said.

"It is not about coming through. We know that if you get passive against City, you don't have to come. If you are active and good, you have a chance.

"If we concede a goal, nothing changes. We are still in the lead. It is all about doing the right things, staying in the mood where we can bring in our strengths. Playing in the right spaces, defending in the right spaces, attacking them in the right spaces.

"It would be the same if they were 3-0 up. It wouldn't change anything. Just defending against City is not the solution. That is why we shouldn't try it."

If Liverpool score once on Tuesday, City would need to score five to go through.

Liverpool, though, have already surrendered a three-goal lead in Europe this season as they drew 3-3 with Sevilla in November. They were also beaten at City 5-0 in September when Sadio Mane was sent off in the first half.

"Of course we are different," Klopp said. "When we lost here 5-0, it was clear already that City is a fantastic team. We conceded one goal, we had our chances, then the red card.

"It is different, it should be different, we are longer together. Things are better tuned. It shows us that these kind of things are possible but we don't need that information.

"We have to be at our best but that is how it should be if you want to go to the semi-finals of the Champions League. It's what I said to the boys before the first game.

"It is not about coming through somehow. Be at your best: you can still be beaten. That's possible. But then you know the other team was better and it wasn't because of you. So let's try and be at our best. Then we will see where it leads us to."

City enter Tuesday's game on the back of a 3-2 defeat to rivals Manchester United that saw them miss out on the chance to secure the league title.

Instead of focusing on City's collapse after half-time, Klopp was more concerned with the attacking play from the hosts in the opening 45 minutes that, he felt, warranted more than a 2-0 lead at the time.

"It was one of the best first halves I ever saw. It was like a thunderstorm," Klopp said. "Then in the second half one goal changed the game. City have still conceded the least goals [in the Premier League]. They don't have these problems a lot.

"It is bad that it happened in the game before our game because maybe they have had time to address the problem.

"Our boys deserve a lot of respect for their performance from the first game. Now let us play and enjoy and we will see what happens in the second game."
