Paul Lambert insists the 2-1 loss to Arsenal has done little to dent the confidence and belief in the claret and blue camp.
Lambert called the defeat at The Emirates "harsh" as his side played with gusto throughout.
And he says he won't need to pick his players up because the performance level was so high in an engaging contest in the capital.
He said: "The belief is there. We have been playing well for a number of weeks.
"We should have seen the game through at Everton and West Brom and we should have got something in the Newcastle game after the second half.
"The West Ham win then gave us a massive lift.
"We have been beaten today. But with the performance, we will take great heart from it.
"The confidence is there, that's for sure. And we are playing well enough. The way they are playing is a very, very high level.
"If we can keep playing like that? I don't need to rebuild the confidence after that. But I haven't for a number of weeks now. The confidence is there.
"The team were excellent against Arsenal. I don't think we deserved to get beat.
"We looked a threat throughout the whole game. In the first half we should have scored. But the way the lads played, I couldn't fault them.
"I thought they were excellent throughout.
"I felt we should have scored more than one goal. And I thought we should have been in front at half-time. I thought we were unlucky to be down.
"But we came out in the second half and went again - and got the equaliser. The equaliser was a brilliant finish, from a fantastic counter-attack.
"I then thought the one when Christian went through, he maybe should have slipped Andi in. A bit more care and we maybe would have got another one.
"But we certainly didn't deserve to lose the game."
Meanwhile, Lambert revealed Ron Vlaar [calf], Darren Bent [foot] and Shay Given [strain] all missed the game through injury.
He will assess them in training now ahead of the Man City game.
