Leeds' Daniel Farke:
"We have had some electrifying performances in the home games with many goals, but this was our most mature performance of the whole season.
"Cardiff is always a difficult place to go, to be in so control of the game from the first to the last second makes me pretty happy.
"We kept them totally quiet in their possession and we dominated the ball in a fantastic manner.
"We probably should have scored a few more, but the win was never in doubt and I was especially pleased with the control we had.
"Sometimes when you are so dominant in the first half with a 2-0 lead you are too comfortable and sit back a bit too much.
"But it's important we stayed with the foot on the gas and pressed them high.
"Cardiff is by far the best side in terms of set-pieces in this league, so it's important you keep their game from your goal.
"You have to press them high and make sure the ball is in their half and that you are really accurate in your possession.
"I like the mentality. I've criticised them in the last away games when we've had setbacks - penalties denied and red cards - and found it difficult to grind out a result.
"But we were really on it and showed resilience. It was nice to watch our football, it was pleasing on the eye."
Erol Bulut was blunt and to the point
"I am not in a good mood, this team can give much much more.
"We didn't expect to lose a game like that. We know Leeds are a strong team but my players respect them too much."
