The French defender says the squad are prepared, relaxed and focused, but accepts Lyon represent a very difficult hurdle to progress to the Champions League semi-finals.
“Of course it would be massive for the Club to win this competition and we are going for it,” Laporte said.
“I think the team is prepared because we have trained since the beginning, thinking of every single game.
“We prepared for the Champions League like the manager said. We are focused on this competition.
“Hopefully, we can beat Lyon tomorrow. We are prepared and believe we can win the Champions League.
“Tomorrow we have to fight and this is what we have to do - compete and fight until the end. We have to be ready for the fight.
“Lyon are like the other teams that are here - a tough side. They have a lot of good players, but we have to be focused on ourselves.
“We know they have talented players and we have to focus on the game and not concede mistakes.
“In simple terms, we have to try and score more goals than them. That’s what I can say now.”
And Laporte admits he is looking forward to playing a French side – and hoping he can replicate the goal he scored against them last season when City drew 2-2 in a group stage clash in Lyon.
“It’s always special when you play against a team from your country,” said Laporte.
“I am excited to play against them. I remember when I scored against them last time we met. Hopefully, if I play I can do it again and we can go to the next stage.
“As I say, we have to fight until the end and try to win the game and then take it from there. We are ready.”
