Leeds boss Marcelo Bielsa said:
"I did not get the preparation right because I knew about Cardiff City's strengths and we didn't resolve it.
"We knew how dangerous they are in the air and from set-pieces. Set-pieces are crucial in this division and Cardiff made us pay in that area today.
"Some of our attacking play was the best I have seen from Leeds and It is difficult to explain the result. There is no way we should have drawn that game."
Cardiff City manager Neil Harris said:
"It's a hard one because Leeds were obviously better than us and as bad as we were at times defensively to give away really poor goals, I can't do anything but praise my players.
"The character in the group, the desire in the group, the ability in the group to come back and score goals is first class.
"So I'm a very happy manager with a point and I'm very pleased with the thought process of the team to come from behind. However, for us to move forward we've got to be better than we are at the moment. We're conceding cheap goals.
"Lee Tomlin's goal was a brilliant finish, he has got great ability and that moment got us back into it. I have got 11 points from my six games in charge so I am really pleased with that return. The message is getting across and the confidence is growing."
