Town defender Luke Chambers finds it difficult to explain the team’s current form surge that has taken them to within two points of a coveted top six slot.
The stand-in skipper, who wears the armband when club captain Carlos Edwards is absent from the starting line-up, admitted: "It’s difficult to put my finger on it.
"I don’t think performances have been too different. We continue to do the same things but we have probably put together more sustained performances.
"We had been having 45 minutes of very good football, followed by a second half where we dropped off a little bit, and I think we have increased that to 60 or 70 minutes.
"Opposing teams are always going to have good spells but I think we have limited them and we look like we are asserting ourselves more and also taking our chances when they come along.”
The current run of form — three wins on the trot and four in their last five games — has boosted morale, although even players in a struggling team are usually quick to assure supporters that morale remains high even when results are not forthcoming.
But Chambers added: "Lads can say what they want but when you are down at the bottom it is always difficult to keep morale up.
"You don’t have three wins on the trot in the Championship very often — in my career I can’t remember it happening too many times — so we’ve got to enjoy it and hopefully make it four at Forest on Saturday.
"If we do people might sit up and take a bit of notice of us but we’re happy to keep going along the way we have all season. It’s still early days but I think we are going in the right direction.
"At the start of the season some people said we might have a chance and others wrote us off.
"We’re quite happy to stay down here in Suffolk, make it a long journey for teams to play us at Portman Road and make sure they go back with nothing in their pockets.”
