But the Frenchman believes that the manner of their 3-1 win at Newcastle on Saturday shows that their fighting qualities - so evident last season - are returning.
Clichy told City TV: "The only thing we have been missing this year is probably a bit of spirit. From last season, people expect more from us - our fans, ourselves.
"Last season was a great season, but like the manager says, we have to put this behind us and start to work.
"This could be an example for everyone because the work-rate was unbelievable from the players up front to the defenders and Joe Hart. That's the spirit we have to have.
"We know the quality is there - we can score, we have seen it since the beginning of the season that we can score against any team, any time, but we just need this extra fighting spirit and on Saturday, we had it.
"We lost the game against Manchester United, a great team. From 2-0 down, we came back to 2-2 and unfortunately lost in the last minute to a free-kick.
"Of course it was a disappointment because we lost the three points, but there were plenty of positives during the game.
"One game is not the end of the world and we just wanted to stay focussed for this game (Newcastle), and now this game is over, we are going to think for next week.
"We are just going to take game after game and see how it goes."
