Norwich bounced back from successive heavy defeats on the road in the Sky Bet Championship to record a much-needed second league win of the season.
They put consecutive four-goal reverses at Aston Villa and Millwall behind them by turning in a solid performance that brought a deserved reward.
The all-important goal came after five minutes, with Nelson Oliveira sliding the ball home from close range after Timm Klose had taken advantage of poor defending at a corner.
“It was important to have a day like this when you have a really good performance,” he said. “I though the win was fully deserved. We scored early on and then created a lot of chances.
“When you don’t take them it can be a bit of a struggle towards the end, with the long balls going into the box, but we coped with it well.
“I was pleased with the win and also with the clean sheet. We defended really well and they didn’t have many chances to score.
“In fact I can’t remember a clear chance – there were a couple of free-kicks from outside the penalty area, but nothing else.”
Farke was pleased with the way his side responded to the pain of a 4-0 defeat at the New Den.
“I was delighted with their positive attitude, the way they approached the game,” he said.
“The supporters were excellent too, what happened in our last game can’t have been easy for them.
“Sometimes when there are times of change at a football club it can be a bit of a roller coaster – things don’t always go the way you want them to do but today was excellent.”
Birmingham boss Harry Redknapp firmly believes his side will be challenging for promotion at the end of the season, despite winning just one of their opening six games.
“I am not a fool. I have been around long enough to know that I have got some very good players here,” he said.
“There’s is no way this team will be struggling at the end of the season. There is enough ability here to be right up there – remember there are still 40 games to play.”
There were six new signings in the Birmingham side and Redknapp added: “We managed to get a bit of work done on the training pitch but there was a bit of throwing them all in and seeing how it gelled.
“The one thing I do know is that I have got a better team now than I did two weeks ago.
“Today we dominated possession against a team who usually do that to the opposition but we lacked a cutting edge in and around the box.
“We just couldn’t make things happen. They scored early and that was basically that.”
