Barry Ferguson blamed his side’s lack of self-belief for Saturday’s 3-1 defeat at Leicester.
The Seasiders stunned the King Power Stadium as David Goodwillie gave them a half-time lead following a battling, backs-to-the-wall display.
Ferguson set his side up to be tough to break down, a plan which was working well until Ruyad Mahrez’s wonder-goal brought the Foxes level just past the hour.
And it was his side’s reaction to that equaliser which worried Ferguson most.
“We did well until they scored, then we felt sorry for ourselves,” the boss said.
“Once the goal went in, we dropped far too deep and encouraged them to come on to us. After that there was only one team in it.
“It’s just a mentality thing. It annoys me that once we concede a goal, that’s it.”
Ferguson opted for a 5-4-1 formation for the first time in an attempt to frustrate Nigel Pearson’s Championship leaders, who had won 12 of their previous 14 games.
And despite some lucky escapes early on, it looked as if Ferguson’s tactics were going to work.
He added: “They did what I asked of them in the first half down to a tee. I know we rode our luck a couple of times but we played the high line well.
“I made it clear at half-time that we had to be the same again. But the guy scores a wonder-strike and then we think, ‘Leicester are a great team – we’d better stand off them a bit.’ That’s not what I want.
“We sat too deep and I cannot shout any more from the sidelines. I cannot tell them any more.
“It doesn’t bother me if it’s Barcelona or Real Madrid we’re playing. Leicester are a good team and are top of the league, but there’s nothing to be scared of and we showed that in the first 60 minutes.”
Late goals from Wes Morgan and former Pool striker Kevin Phillips won it for the home side but there were plenty of positives for Ferguson’s men.
Results elsewhere in the relegation battle went Pool’s way, with Yeovil and Barnsley both losing, and Millwall and Charlton playing out a goalless draw.
It means Pool remain nine points clear of the bottom three but Ferguson was far from happy.
“I have been trying my hardest,” he said. “At times I have thought we were getting there and then I have been knocked down again.
“We have to be able to handle the pressure because we are still a million miles away from being safe.”
“And we’re getting closer and closer to the end of the season.”
