McLeish upset with Birmingham defensive gifts
"It was Christmas come early for Bolton today," McLeish lamented.
"We were well in the game when Bolton scored and I thought we had a little bit of the pressure in their half for a change.
"They obviously dominated territorially but the last 20 minutes was pretty hard to take."
McLeish added: "The lads came in and held their hands up and apologised, but saying that they know in the Premier League the standards are that mistakes should be very rare - and it's got to be a right few games before they make another.
"I spoke to the players but it's private and always will be.
"I can't fault their effort, but the gifts must affect the rest of the team."
