Samuel Saiz scored his sixth goal of the season in the first half and substitute Stuart Dallas rammed home a low finish in the final minute to make sure of the points.
Victory lifted Leeds top of the second tier for the first time since the opening day of the 2004/5 season, but the boss is not getting carried away.
“It's just a situation at the moment,” he said. “If you tell me it's the last game and we're in that position I would be happy, proud and all that you can say about that.
“But right now, don't give me anything. It puts a bit more pressure on the team because everyone now wants to beat Leeds.”
And the manager was happy to take the win despite the fact his charges were not at the top of their game.
“The performance was not the best, but if you still take the three points you have to be proud,” he added. “What we have done until now is a high level.”
