"It's just not good enough," he said. "Just frustrating because we've done it now in the last three first halves and fundamentally that lands on my shoulders.
"It's just infuriating. And the goals are just... they're not even schoolboy goals, they're just really poor goals to give away.
"Then (in the) second half, we have a little bit more confidence (Huddersfield were taking it easy by then).
"We know what we're capable of doing and we fell well below the standard that we set.
"I ain't going to dress it up. Fundamentally, that falls on me. Whether that's team selection or I can't manage a football club, I give my all every day.
"I know what's needed, I know where we need to get better. We're going to have to do a lot of business in January. How that looks, I don't know, but I'm fully committed to the cause, the staff are fully committed and when we perform to the levels we're capable of doing, we're a good team.
"However, today and in a few first halves we've just given schoolboy goals away.
"I've been first to say that when we don't get to those levels, that is on me and that is on me today.
"Teams come here and take three points off us and are miles better than us. I'm the first to say we couldn't live with them, we couldn't stop them, the goals were great goals, yada, yada, yada. That wasn't the case today, we beat ourselves."
And on the anger of the fans, he said: "I get like this.
"Listen, I'd boo. I ain't going to sit here and say it was good. I'd boo, I get it.
"But throw that at me, don't throw that at players. We'll get back to the football club we should be. There's a number of things I ain't going to openly talk about here that need to change and move on, and for this club to move on.
"We'll get there.
