Daniel Farke says a two-week break from domestic action has allowed for a full reflection on the Sky Bet Championship season so far as Norwich City prepare to host Birmingham City.
The Canaries come up against Harry Redknapp's men on Saturday, a fortnight on from a 4-0 defeat at Millwall.
"It's been good to judge things in a neutral and objective way," Farke told the media on Friday afternoon.
"We want to improve and fight back after such a setback. This season has been a bit of a roller-coaster so far but we expected that a bit in the early stages.
"It's been a big change and you can't just press a button to make it okay. When you have a setback, you need to stand together.
"The guys on the pitch need the support but we have to perform."
City's boss believes Blues will provide a stern challenge, given the extent to which they have altered their squad in recent weeks.
"Harry Redknapp is a really experienced coach, Farke added.
"They've signed 14 new players since August 21. That means they have a new style.
"We need patience. It will be hard to create chances against them. In defence, I want an attitude where you give your life to defend your goal.
"I want this attitude always. We've spoken about that and are looking forward to the game."
