The Reds boss leapt to the defence of his team after their underwhelming performance in the game at the Etihad Stadium in Manchester, where City produced an impressive display.
Speaking to Sky Sports, Klopp explained: "If you want to lead the story in the direction that we were not focused on that game, then do it.
"I saw a brilliant attitude. I saw fight. We didn't behave like somebody who became champions a week ago."
The one-sided game was only Liverpool's second defeat of the Premier League season.
However, Klopp thinks that with City's quality, the loss shouldn't be considered a huge surprise.
He said: "If there is a team in the world that can smash us like this, it is probably City - but we will come again. We lacked fluidity, that's for sure. And in some 50-50 situations they were quicker than us in mind.
"They used their chances and we didn't. City are incredible. I've seen their games - they haven't played a bad game all season. Even when they lost they still played really good football."
