Alex McLeish was left to bemoan his side's defending in the 3-2 loss to Stoke.
Blues were sunk by a late Dean Whitehead goal after strikes from Keith Fahey and Cameron Jerome had cancelled out Stoke's two-goal lead, given to them by Robert Huth and Ricardo Fuller.
"It would have been a great point and I thought the way we were going at the time (of the equaliser), the momentum was with us," the Blues boss said.
"We were right on top at two each, and their third goal was a dog's breakfast of a goal. It was shocking.
"We have lost some uncharacteristic goals this season. The defenders have not been poor individually - we have still defended well and we saw Scott Dann and Roger Johnson battling against two big centre-forwards, a good 50-50 battle.
"But to lose the goal the way we did was soft to say the least."
