Wolves boss Mick McCarthy blamed poor defensive play for his side's 1-0 home defeat to rock-bottom Portsmouth.
Pompey had lost their first seven Premier League encounters of the campaign but finally got off the mark thanks to Hassan Yebda's first-half header.
Wolves had chances to equalise after the break but Paul Hart's side rode their luck to claim a vital three points.
A dejected McCarthy admitted after the game: "It's a disappointing day. I didn't think there was a great deal in it until their goal went in and of course that has a huge bearing on it and they had the better of the first half.
"I don't want to talk too much about whether we should have had a penalty because it sounds like I'm bemoaning my luck and I'm beleaguered and all that.
"If we defend a corner properly and the second ball that comes in then it isn't so much of a big deal and if it's 0-0 then maybe I'd discuss the decisions that didn't go our way.
"If it's a penalty then he should give it and I've seen it and it looks like a penalty but there's no point me speculating on it.
"We're coming off with a defeat because we didn't defend properly. We weren't outplayed, we just didn't do the basics properly.
"We played well in the second half and had a number of opportunities we should have done better with. They've done the basics and stopped us scoring but we didn't manage that with them."
