Parkhead manager Wilfried Nancy has insisted he is still "together with the board" and expresses belief that "the team can turn things around" despite a concerning 3-1 loss to Rangers, which marks a sixth loss in their last eight outings.
The Frenchman hailed an "exceptional" first-half performance from his side, a period in which they took the lead through Yang Hyun-Jun and passed up a number of clear chances.
However, their city rivals fought back after the break, capitalising on the Celtic's defensive fragility with a two goals from Youssef Chermiti and a third strike from Mikey Moore.
This result sees Rangers draw level on points with their rivals Celtic, who could find themselves six points behind table-toppers Hearts depending on the evening result.
Addressing the media, Nancy commented, "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 the situation. This is not about the players or the tactics, this is about key instances."
"This is not about myself, this is about disappointing the fans because I know the significance of this game. I can appreciate the disappointment, but I also saw what we're capable 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 truly believe we can turn things around."
He concluded by reiterating, "The manager and board are together with the board."
Former Scotland midfielder Michael Stewart offered a brutal take: "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 facilitated this should be shown the door as well. Celtic are in an absolute state."
Former Celtic goalkeeper Pat Bonner identified the problem: "The problems aren't high up the pitch for Celtic, the problems are the organisation 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 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 sentiment among supporters was one of anger and calls for change.
Pete: First 45 minutes looked great, after the break we looked like amateurs. Nancy has a single 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 system. These players are not poor 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 scapegoat. 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 refuses to alter. We've been beaten by a mediocre Rangers team. Nancy must go.
