Hayden Mullins netted the only goal 19 minutes from time and the new Elland Road manager said: "I thought we should have got something out of the game.
"When it was 0-0 we were on top and then they scored from nothing.
"When I arrived at the club I put my reputation on the line and to make sure Leeds remained in this division. So far, as I am concerned, it is job done.
"Everyone must be going in the same direction. If that occurs at this club you have a major chance.
"I think we have to talk about who needs to come in. If we can add to the squad with good quality players we should progress.
"Leeds were in trouble when I came in. I am delighted with the boys. They played two games at home and we won them both. They were pressure games."
