Leeds manager Neil Warnock was left "embarrassed" after his team slumped to a 7-3 home defeat by Nottingham Forest.
Warnock hoping to inspire a Championship promotion push, but Leeds are 10th and let in seven at Elland Road for the first time ever.
"I'm quite embarrassed about the result," Warnock said. "You've got to be stronger mentally in certain areas to avoid results like that.
"I've learnt probably more tonight than I have in the other games."
The result leaves Leeds five points adrift of the play-off places with just one win from their last six games.
Robert Snodgrass slotted home an early penalty to put the hosts ahead but Forest hit back with a stunning strike from Adlene Guedioura.
The impressive Garath McCleary put them in front just before half-time and Dexter Blackstock further increased Forest's lead.
Two goals in as many minutes, from Luciano Becchio and Michael Brown, drew Leeds level but McCleary struck three times in the space of 15 minutes before Blackstock added a seventh.
"I don't think you learn much about your players when you're winning games," Warnock continued.
"I think you learn things when things go against you, who stands up and who you want in the trenches with you.
"In fairness some of them were just shattered. We're a bit thin on the ground, but I don't think the centre-backs played poorly, I just thought every shot was going to go in.
"We've fought back really well but the fourth goal was terrible, it was a Sunday League goal."
Forest boss Steve Cotterill, whose team are now seven points clear of the relegation zone, added: "It was a stunning game.
"I know we've won but Leeds United played their part as well. Our chances went in, but they played their part.
"I thought it was an outstanding game by both teams, we're very pleased with the three points more than anything else.
"But to play in the manner we've played, we've done that a lot this season and ended up losing 1-0 so maybe it's evened out a little bit."
