Lee Clark hailed the Blues rearguard following his side’s narrow win at Ashton Gate.
Blues were in control for large periods of the contest, but Bristol City remained a threat throughout, particularly in the second-half.
The visitors had a couple of chances to put the match beyond the Robins, although it was Sean O’Driscoll’s men who looked the more likely to score at times.
Clark told bcfc.com: “I thought the back four were fantastic tonight because I don't think we particularly passed the ball as well as we can. I think we got sloppy at times and we didn’t really see the game off the way we should have.
“But I just said to the players ‘when you come away from home and keep a clean sheet, 1-0 isn’t too bad a result.’”
Birmingham hold one of the best away records in the npower Championship, having lost just once on the road in 2013.
And whilst encouraged by such a run, Clark wants to see his team produce that form at St. Andrew’s as well.
He added: “We just need to play on the front foot and we need to start games properly and not give teams two, three-goal head starts. We don’t do that away from home. We obviously did that at Hull and we got well beaten but that was the only blip.
“At home, I know you’ve got to entertain in front of your fans but you’ve still got to keep it tight. We do lots of things late in the game so the longer the game’s still in the balance, we’ll give ourselves a greater opportunity to win, because our fitness levels and the amount of goals we score in the last 30 minutes of games is one of the highest in the division.”
