Dundee manager Barry Smith says his side’s display in the 3-1 defeat to Aberdeen was ‘as poor as we’ve been all season’.
A hat-trick from Niall McGinn gave the Dons all three points with Mark Stewart scoring what proved to be a consolation goal for the hosts.
Smith admitted he got his team selection wrong but refused to accept that his side will finish bottom of the SPL table at the end of the season.
He said: "That's as poor as we've been all season. I've got to be honest about that.
"But I'll hold my hands up and admit that I got it wrong with my team selection.
"There were a lot of tired legs after the Celtic game so personally I should have looked at it.
"In hindsight, I should have changed it because it was a demanding game where the boys really put in so much effort.
"I'm not talking about individuals. It's over and I will learn from it for sure.
"We looked tired and that didn't help us on the day."
In their final game of 2012, the Dark Blues have taken 12 points from their 20 SPL games so far this term.
Smith added: "We were not at it all day - simple as that.
"I thought maybe there was a spell during last five minutes of the first-half when we started to get into things a little bit.
"We're obviously never happy getting beat but it doesn't matter if it is December, January or whenever.
"We want to win as many games as possible but we just didn't do enough today which was the disappointing thing.
"Our confidence will be dented after this performance which is understandable.
"But make no mistake the spirit will remain the same.
"It's always been good and that will never change as we have a right, good dressing-room atmosphere.
"We've been in difficult situations before and come through them so we just have to stick together and try to do the same again.
"We've got a lot of strong characters in the dressing-room who will be fighting for everything.
"We've got another big game coming up at St Johnstone in midweek which we'll get up for and get ready to go again."
