Parkhead manager Wilfried Nancy has declared he is still "together with the board" and expresses belief that "we can turn things around" despite a concerning 3-1 loss to Rangers, which represents a sixth defeat in eight games.
The Frenchman hailed an "outstanding" first-half performance from his side, a period in which they took the lead through Yang Hyun-Jun and passed up several other clear chances.
However, their city rivals roared back in the second period, exposing the Celtic's defensive fragility with a double brace from Youssef Chermiti and a final strike from Mikey Moore.
This result sees Rangers move level on points with their rivals Celtic, who could end up six points adrift leaders Hearts depending on the evening result.
Speaking post-match, Nancy stated, "The result was disappointing because we merited a better outcome today, but again we required more goals."
"In the second half, we conceded three goals from set-pieces. It's tough to accept, but it's reality. This is not about the individuals or the game plan, this is about key instances."
"This is not about me, this is about letting down the fans because I know the meaning 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 turn around. If it was not the case, I would not talk like this. I truly believe we can reverse our fortunes."
He concluded by stressing, "The manager and board are together with the board."
Analysts Give Stark Verdict on Celtic's Situation
Former Scotland midfielder Michael Stewart offered a brutal analysis: "Unworkable position for Nancy. He looks like a broken man. The gap between the manager and the team is so obvious."
"It is not something that can continue and it should not have happened. The people on the board who facilitated this should be removed as well. Celtic are in an absolute state."
Former Celtic goalkeeper Pat Bonner pinpointed the issue: "The problems are not high up the pitch for Celtic, the problems are the shape at the back and the defensive qualities."
Former Rangers striker and coach Billy Dodds added: "As much as Rangers have done the correct things in this second half, Celtic have been just brutally bad."
"Celtic have just capitulated. 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 doesn't do that."
Supporters' Views: Understanding for Nancy But Growing Calls for His Departure
The post-match mood among the fanbase was one of frustration and demand for change.
Pete: First 45 minutes looked great, post half-time we looked like amateurs. Nancy has a single way of playing and can't adapt. Get him out now!
Iain: It's very painfully obvious that Celtic cannot play to Nancy's system. These players are not bad players all of a sudden. The answer is self-explanatory.
James: The board are wholly to blame. I feel sorry for Nancy as he should never got the job in the first place, but he'll be used as the fall guy. We don't have the players for his system.
Andy: Nancy has to go. I've been one of those wanting to give him a chance, but there is no progress. He has a formation that he won't change. We've been beaten by a poor Rangers team. Nancy must go.
