Gary Rowett was delighted with Birmingham's determination to come from behind and claim a superb 2-1 Sky Bet Championship home win over Sheffield Wednesday.
The Blues boss praised the courage and tenacity of his side to snatch the points after going behind to a Gary Hooper goal.
Clayton Donaldson converted an 80th-minute penalty and then Lukas Jutkiewicz grabbed an injury-time winner to down Wednesday.
Rowett later praised the brave performance of his team and in particular the way substitute Jutkiewicz was on hand to score the vital second goal.
The former Burnley striker was highly complimented for his match-winning display, with Rowett saying: "I was really pleased for him. There have been a lot of things said about him and his goalscoring record over the last season-and-a-half.
"He has had a very bad injury and most of his appearances have been coming on as a substitute. He is a real team player and it was a fine example of our squad. The players who came off the bench won us the game."
Rowett admitted that it was ominous when substitute Hooper gave Wednesday a 76th-minute lead.
It was Hooper who scored both goals for Wednesday last season to give the Owls a 2-1 win after coming back from a goal down.
Rowett admitted: "We owed them this result after what happened last season."
On this occasion it was Birmingham who had to battle back after Hooper's goal to produce a hard-earned win with Donaldson putting Blues back in the game from the penalty spot.
Rowett added: "There was some good play leading up to the penalty. Donaldson put the after-burners on with a real burst of pace and deserved the penalty.
"He showed some character with his penalty-taking record this season. With some of the ups and downs he has had this season to make it 1-1 was very satisfying.
"The way we worked hard when we were not playing well certainly gave us the opportunity to do what we did late in the game.
"The changes we made in terms of tactics gave us the chance to get back into the game. Against a team like Sheffield Wednesday you always have to ride out 15 to 20 minutes which I thought we did really well."
Sheffield Wednesday manager Carlos Carvalhal could not hide his disappointment with the result.
He said: "I do not remember one occasion when my goalkeeper Keiren Westwood had to make a real save before Birmingham's two late goals.
"This is why I am frustrated because in the game we created chances and didn't score.
"I do not want to comment about the penalty. It is a referee's decision."
Carvalhal dismissed concerns about Wednesday's away form as they have now gone 10 games on the road in all competitions without a victory.
He said: "I am very happy with our form. We are playing fantastic but not scoring. We again had five good chances against Birmingham.
"If we were not playing well I would be concerned. We play to win but we need to improve our finishing."
