Nottingham Forest goalkeeper Lee Camp says that team spirit under previous manager Steve McClaren was the lowest he has ever known in his career.
Since McClaren quit in early October, Camp says that new boss Steve Cotterill has lifted the mood a great deal.
Camp told BBC Radio Nottingham: "I think morale was as low as I have ever experienced in the changing room.
"The manager has come in and has got morale back up. He is full of beans, he is lively and it has helped."
Forest won just two of their first 11 league fixtures this season - but then won their first two games under Cotterill before suffering their first defeat, at home to Hull City on Saturday.
And Camp, an ever-present as the Reds reached the Championship play-offs for the second consecutive season under Billy Davies last term, now admits that the atmosphere around the City Ground at the start of the season was not good.
"For whatever reasons there was a lot of negativity around the place which seeped into the changing room," he said.
When asked what had changed under Cotterill, Camp added: "A lot of it comes to morale. We are set up different, we have a different tactic and then there's the intensity of the manager.
"I think there is a bit of a fear factor back in there now and players are at it.
"For whatever reason, it didn't work under the previous manager and the approach is similar to when we've had success."
