Paul Jewell admitted his Ipswich side lack the confidence to see out matches after being held to a 2-2 draw against Huddersfield at Portman Road.
The Tractor Boys fell behind to Adam Clayton's strike but turned the game on its head thanks to goals from Luke Chambers and Michael Chopra.
However, James Vaughan levelled 10 minutes from time before the same player spurned an opportunity for the Terriers to take all the points when he saw a penalty brilliantly saved by Scott Loach.
"When we get into a winning situation we haven't got that air of confidence to see games out," said Jewell. "That's been the case for a while.
"We've lost two games in the last week - one heavily and one to a team in the league below us - and the question marks were there.
"But we showed plenty of guts and played some decent football. It was important to get something out of the game.
"We know we need to improve defensively, though, and there was a 10-second passage of the game that summed us up - we hit the inside of a post and then the ball went straight up the other end and they won a penalty. That can't be right."
Huddersfield boss Simon Grayson was pleased with a point despite the missed penalty.
He said: "It was an open game and there were plenty of chances for both teams. We could have won it and could have lost it.
"We had an opportunity to win it right at the end, with the penalty, but I'd have settled for a point before the game. We still wanted to win it, even at 2-2. We could have got bodies behind the ball and shut up shop but that's not my philosophy. I'm sure both managers will have been happy with a point."
