Chris Sutton, the former Celtic striker, was on BBC 5 live this week talking Brendan Rodgers.
"The manager has to take responsibility - bottom line, too many players aren't playing up to the level, they aren't scoring enough goals and, for Brendan to come out and say he is alarmed, is alarming in itself," he said in reference to their 2-1 defeat to Kilmarnock on Sunday.
"It's an enormous couple of weeks for him.
"I am covering the League Cup game on Wednesday and it can all unravel really quickly."
Rangers, their bitter rivals led by Steven Gerrard, are above them in the table. It is their worst start to a campaign in 20 years.
Rodgers has done the double treble with the Hoops and completed an invincible season; you'd think that would buy him some time. It clearly hasn't.
Why is it all unravelling for the man who Swansea tried to bring back to South Wales in the summer of 2016?
Are we seeing a reflection of what happened in the final months at Liverpool, where everything that was once stable began to crumble around him?
A summer of discontent
Before we even look at this season, the summer has to be examined.
Celtic had an appalling transfer window - something Swansea City fans will empathise with - as Sutton points out.
Defender Dedryck Boyata dominated the summer; the Belgian was keen on leaving for Fulham but it all turned a bit ugly with reports suggesting the international refused to train.
"It is his responsibility more than anybody else's because he (Rodgers) let this situation, in my opinion, fester with Boyata," Sutton added.
"They royally messed up the transfer window. The Boyata stuff was really unsavoury. My feeling is they should have got rid of him.
"He downed tools and Celtic got knocked out of the Champions League by a bang-average AEK Athens team. If Boyata had played, there is a chance they would have gone through."
The Moussa Dembele saga also had a negative impact, the striker eventually joining Lyon for £20million, but the airing of dirty laundry in public gave Rodgers a headache he could have done without.
"You can't let your top striker move on without even having anyone to come in and replace him. We need three strikers." He left anyway, leaving Rodgers in an awkward position indeed.
They failed to land Swansea target Scott McKenna from Aberdeen also rankled. It was a disaster.
This season starts with a whimper
With six games gone, Celtic sit sixth on 10 points, with Hearts, Rangers, Hibs, Livingston and Kilmarnock above them.
The season maybe young, but they have dropped eight points already.
In Rodgers' first season, they dropped eight points across the entire campaign.
There is no question Celtic are in a pickle.
The same vibrancy hasn't been there this term and they have only scored six league goals.
For the first time in his Celtic career Rodgers is coming in for criticism. But the fact he himself is fanning the flames suggests there is a deeper issue at Parkhead.
He seems at loggerheads with the club's board over transfers; by and large he got who he wanted at Swansea but at Liverpool players were bought by committee. Friction came about as a result.
The signing of Daniel Arzani suggests there is a disconnect at the club. He was signed, but was not named in the Europa League squad list.
What has he said?
The lowest point of his Celtic career so far was the defeat last Sunday.
"When you are a huge club, the demand is to win," he told BBC Scotland .
"In the last couple of years we've done that really well and playing in a style that is synonymous with the club. It hasn't been the same but we have to work to make it better.
"It's a poor result for us but we have to go away now and take our medicine and get ready for Wednesday [a Scottish League Cup quarter-final trip to St Johnstone]."
When asked if Celtic fans should be alarmed, Rodgers replied: "Yes, I think they should."
The expert view
A big thing for any manager to admit, that.
Darren Cooney, of the Daily Record, picks up the story here.
"It could have just been candour, an acceptance two defeats and one draw from six games simply isn’t good enough," he said of Rodgers' Killie post-match comments.
"Generally, though, a manager of Rodgers’ calibre and intellect rarely makes off-the-cuff remarks.
"It is almost always considered, a message intended for someone. Indeed, when the Irishman was first asked the question by the BBC, there was a pause; a moment when Rodgers took time to answer to ensure his reply perfectly reflected his view.
"So when Rodgers said the fans should be alarmed, he meant it. To who it was directed at, however, is anyone's guess."
Defiant Rodgers
At his press conference on Tuesday, Rodgers came out swinging, rejecting claims from Kilmarnock man Kris Boyd that the Celtic dressing room was split.
The Irishman said: "When teams lose games the logic used to be and clearly still is, there is a split in the dressing room.
"Sometimes there is no plan B - that is another accusation. For us, we are very much unified as a club. We have set high standards but we are very much together.
"We've set such a high standard over these last couple of seasons. Yes, we haven't started as well as we wanted in our season but we are very much together.
"Kris is probably best suited trying to get himself into the Kilmarnock team to get playing and we will concentrate on our own job in here."
Rodgers had a message for the supporters.
"My message is I am privileged to be here," he said.
"I love my work here. I love my challenges here. I’m looking forward to the next stage of the season to show our fighting qualities.
"I take full responsibility for our two defeats.
"I made big changes for those games. Perhaps I made too many.
"At the moment we’re maybe short on our variety of play. But it’s my responsibility to take the team back to that."
What happens next?
Former Celtic striker Ian Wright says he wouldn't be surprised if Rodgers walked away now.
"I'm not sure what more, with all due respect to Celtic, he can do there now," he said.
"If he was linked away and he came out and said 'I feel I've taken them as far as I can, I've got two trebles', he could probably use that to say he wants a new challenge.
"You could see that happening and, no matter what you say, he can get teams playing well. He would be sought after."
Will Rodgers walk? As Wright states, he won't be short of admirers. Rodgers has his supporters in the Emirates boardroom and was mentioned before the Gunners appointed Unai Emery. West Ham, too, have been linked with his services.
Rodgers is a victim of his own success - he has set the bar so ridiculously high, how can he ever hit those levels again north of the border?
Whatever, he has a huge job on his hands in the here and now, as Sutton suggested.
He added : “Rodgers has proven he’s a top coach but this season has been poor. Standards have slipped on his watch, on and off the pitch. This needs to work as a wake-up call for Brendan. He has to show his worth once again.”
