Wolves manager Mick McCarthy has hit out at his side's defending in their 2-0 defeat to Birmingham on Monday.
The visitors were handed the initiative when Lee Carsley was given his marching orders for a reckless challenge on Chris Iwelumo.
However, it was the home side who forged ahead when Cameron Jerome capitalised on hesitancy by Wayne Hennessey to open the scoring.
It did not get much better for Wolves after the break, with Garry O'Connor jumping on Christophe Berra's headed back-pass to clinch the points.
McCarthy actually felt Carsley's dismissal hindered his team's efforts, but was primarily disappointed with the mistakes by Wolves' defence.
"We didn't deserve much more than we got to be quite honest," he told Sky Sports.
"I'm disappointed with both goals. Both mistakes. The first one certainly, it was abysmal defending by us.
"We haven't done ourselves any good in terms of defending there.
"There's lots of things I'm not happy about, decisions prior to it, but I end up moaning about it don't I, so our part in it was the biggest bit that cost us.
"I didn't want (Carsley) to go off. It's not ruined the game for Birmingham. It's ruined it for us. After that there weren't too many decisions we got.
"Having scored the goal when they did they were allowed to sit back. Poor, poor game for us."
Iwelumo was stretchered off after being scythed down by Carsley, and McCarthy says it is too early to say whether he will miss any playing time.
"He's got a sore knee," he continued. "We've not been able to assess it properly yet."
