Leicester boss Russell Martin said that changing managers will not bring a quick fix after supporters called for his sacking during the 3-1 defeat to Peterborough.
A section of home fans left the King Power Stadium at half-time after strikes from Owura Edward and Harry Leonard and Warren O'Hora's own goal gave Posh a 3-0 half-time lead in Robbie Savage's first league game in charge.
Emil Riis pulled one back after the break as the hosts racked up 24 attempts, but a lack of cutting edge up front, and soft mistakes at the back, consigned Leicester to a third league home defeat from four this season.
"I can't criticise them because they've seen another defeat and the goals we conceded," Martin said.
"I'm as frustrated as any of them, but if you think changing a manager is a quick fix then I'm not sure that's ever the way.
"We have to keep working. It's as simple as that. It's our job to turn the fans' energy ultimately."

The defeat left Leicester 17th, just a point above the relegation zone.
Martin added: "We're in their box way more than they're in ours.
"I think we create a lot more than they do, but they're really clinical, and defend the box with everything they have, and we don't.
"We're not clinical, and we give up goals that are unacceptable at any level.
"You have to suffer in a game of football and right now, when we have to suffer, we don't look like a team. We look like a group of individuals trying to do their own job, and you can't deal with big moments like that."
On the other side of the coin, the result extended Robbie Savage's fine start to life as Peterborough manager after a 4-1 EFL Trophy win over Ipswich Under-21s in midweek.
"I couldn't have dreamt of that going to bed last night," he said.
"The amount of chances we created through the whole game. They've had a few as well.
"They should have scored just after half-time, they could have scored again, Bassey [Alex Bass] made a great save and the game could have been six-all or seven-all.
"We played high, we played fast, we played dynamically, but also, at times when we had to suffer without the ball, they got into a great shape and a low block."
The former Foxes midfielder was given a mixed reception as Savage returned to the club where he made 204 appearances in a five-year stay.
"Some of the fans were great, some weren't, I don't mind that," he said.
"I don't really care anymore. I do the best for my football club. It's one of the greatest days of my life without question.
"I just can't believe I'm standing at the King Power, two-and-a-half years after I managed at step three in front of 400 people, and winning -- it's incredible."
