Lee Clark was delighted with his side after seeing them beat Leeds 1-0 on Saturday afternoon.
The victory, courtesy of a second half Hayden Mullins goal, saw Blues overtake the Elland Road outfit in table and move into tenth spot.
Clark elected to go with the same formation that had served Blues on their travels in recent months, with Nikola Zigic as the loan striker.
"I don’t like to call it 4-5-1, personally I like to call it 4-3-3 because our wide men are playing so high up the pitch," said the Blues boss. "It’s a tough one because I believe when you’re playing at home you play on the front foot and try and get two strikers on the field but over the last few weeks in terms of results and performances it’s given me a lot to think about in terms of playing this formation.
"It was a terrific win because it was a very tough game. Brian (McDermott) has come in and done a very decent job and has done the job I expect of him because he’s a good manager. They’ve been playing really well in the games he’s had. They pass the ball around; they’ve got good movement, but I'm delighted with the three points and the clean sheet."
It took until the 71st minute for Blues to break the deadlock after Mullins pounced to fire home Nathan Redmond's parried shot.
"We played really well in the first half," he said. "A couple of the younger boys were unfortunate with long-range efforts. We passed it with purpose and we created opportunities and I was really pleased. Just after half time Leeds started dominating the possession a little bit and we got a little bit sloppy, but then we got the goal and I think we kicked on from there. The last ten minutes or so we had other chances to kill the game off.
"I'd said to the players if it was still 0-0 after an hour or so that we had lots of match winners both on the field and on the bench. We’ve got good fitness levels in the latter part of games and we’ve been very impressive in terms of scoring, so it always gives you an opportunity to go and win."
Explaining the decision to start Mullins instead of Callum Reilly, Clark explained: "I’ve just been told it’s his 550th league start. He’s very experienced and that’s why I plumped for him ahead of young Callum Reilly. I just thought the way Leeds were playing and the way they’d changed with the new manager, I just wanted to get a bit of an older head in there to look after Diouf or McCormack who can pop into those little areas to receive the ball."
