Parkhead manager Wilfried Nancy has insisted he is still "in unison with the board" and expresses belief that "we can turn things around" despite a damaging 3-1 defeat to Rangers, which represents a sixth defeat in eight games.
The French manager praised an "outstanding" first-half display from his side, a period in which they went ahead through Yang Hyun-Jun and spurned a number of opportunities.
Yet, their city rivals fought back after the break, capitalising on the home side's defensive fragility with a double brace from Youssef Chermiti and a third strike from Mikey Moore.
This result means Rangers move level on points with second-placed Celtic, who could end up six points adrift leaders Hearts subject to the evening result.
Speaking post-match, Nancy stated, "The result was disappointing because we deserved more today, but again we needed more goals."
"In the second half, we conceded three goals from throw-ins. It's difficult to accept, but it's reality. This is not about the individuals or the tactics, this is about key instances."
"This is not about me, this is about letting down the fans because I know the significance of this game. I can appreciate the frustration, but I also saw what we're able to do."
"I believe we are really close, there are many things that can be improved. If it was not the case, I would not speak like this. I really believe we can turn things around."
He finished by reiterating, "The manager and board are together with the board."
Former Scotland midfielder Michael Stewart offered a harsh analysis: "Untenable position for Nancy. He looks like a defeated man. The gap between the manager and the team is so stark."
"It is not something that can carry on and it should not have occurred. The people on the board who allowed this should be shown the door as well. Celtic are in an complete disarray."
Former Celtic goalkeeper Pat Bonner pinpointed the issue: "The problems aren't high up the pitch for Celtic, the problems are the shape at the back and the ability to defend."
Former Rangers striker and coach Billy Dodds remarked: "As much as Rangers have done the correct things in this second half, Celtic have been just brutally bad."
"Celtic have just collapsed. Something has to change, there is no doubt."
Former Celtic striker Chris Sutton summed up: "We've seen this movie before with Nancy's Celtic."
"You can score, but you've got to defend. This team don't do that."
The post-match mood among the fanbase was one of anger and demand for change.
Pete: First 45 minutes looked promising, post half-time we looked like a pub team. Nancy has one way of playing and can't react. Get him out now!
Iain: It's very clear for all to see that Celtic cannot play to Nancy's style. These players are not bad players all of a sudden. The answer is obvious.
James: The board are wholly to blame. I feel sorry for Nancy as he should never been appointed in the first place, but he'll be used as the fall guy. We lack the players for his system.
Andy: Nancy has to go. I've been one of those hoping to give him a chance, but there is no improvement. He has a formation that he refuses to alter. We've been beaten by a poor Rangers team. Nancy must go.
