Birmingham manager Wayne Rooney:
"We knew coming here would be a tough game. Cardiff are a team who stay in games and nick to nick three points.
"In the first half we took the ball and made it difficult at times for Cardiff. They had moments, especially at set-pieces - Cardiff are the best in the league at set-pieces - so we struggled at times with that but thankfully we got the goal before half-time.
"I was more pleased with the second half. We didn't give them any chances and we didn't look like conceding a goal and had two or three really good chances.
"I'm really pleased with the performance but it's been a difficult few weeks for everyone result-wise, so tonight it was important to get the result. I'm delighted for the players."
