Iron manager Russ Wilcox expressed disappointment at his side's second-half collapse in the 4-1 defeat at Chesterfield.
Paddy Madden had put his side a goal ahead just after half-time, but the hosts hit back with Eoin Doyle scoring a hat-trick before Sam Morsy's late strike."There were lots of pleasing aspects in the first half," Wilcox told The Iron Player.
"But we then fell away and seemed to crumble under pressure.
"It was the most disappointing period that we've had all season.
"We've gone from looking like a team that has quality and that was creating opportunities to a team that looked disjointed and mis-shaped.
"That's why we conceded the goals.
"I've told the players we need more winners in the camp. We need people to stand up and be counted when the going gets tough.
"We said before the game that Chesterfield would have a period of pressure - like every team has at whichever level.
"Their supporters got a massive lift from the first penalty, although they didn't score it.
"We just couldn't deal with that next period.
"We then started chasing the game and were all over the place in the last 15 minutes.
"It's disappointing that everyone with a Scunthorpe shirt on went home disappointed, because there were aspects that were pleasing.
"We played some terrific football at times, created some great opportunities and scored a fantastic goal.
"Rightly so though that is forgotten.
"To concede four in a second half period is so disappointing.
"In the last seven games we've had a clean sheet at half-time, so it gives us a base to work from.
"Chesterfield were in the same league as us last year and we're going away highly disappointed with our showing, particularly in the second half.
"I'm disappointed for the supporters. We had a fantastic following and they got right behind the team.
"Hopes were high after Paddy's goal but it all fell away too easily for me.
"I can swallow losing football matches, but not in that manner.
"I want my players to roll their sleeves up and graft right until the end.
"I didn't see that enough on Saturday and that's a concern.
"We will all be in on Sunday morning and we'll have a look at things.
"Then we'll move forward, because we have to quickly put this to bed and move on to Coventry City on Tuesday night."
