We'll leave it there for this live page, on what has been a remarkable afternoon in Glasgow.

Wilfried Nancy sacked after just eight matches and 33 days in charge.

They host Dundee United on Saturday, but who will be in the dugout, we do not know.

Until then, goodbye.

The big question now for Celtic is what on earth they do next.

Brendan Rodgers walked and Martin O'Neill would possibly be reluctant to take interim charge again.

Would Ange Postecoglou fancy another stint at Parkhead after his short stay at Nottingham Forest? Might Shaun Maloney step up?

As we mentioned earlier, will they now wait until the summer for a permanent appointment and hand someone the reins until the end of the season?

Neil Lennon and Scott Brown are both in jobs. Would managers without a tie to Celtic be keen to walk into such an obviously divided club?

Only time will tell.

Unsurprisingly, pictures of Martin O'Neill's goodbye to the Celtic support last month, following the narrow win against Dundee, are doing the rounds.

The feel-good factor had returned and a split support were united.

I was at Wilfried Nancy's long-awaited first win against Aberdeen 17 days into his tenure, and the drop in mood was monumental.

There were no big celebrations, no sigh of relief from the manager or any outburst of emotion. He was straight up the tunnel, too.

In the post-match interview, he was relatively flat. No different to pre-match when he was under enormous pressure.

Many have said, and questioned, if the Frenchman ever 'got' what it's like being a boss in Glasgow's fishbowl.

I think we now have the answer...

The signs were there right from the first team-sheet that things could go spectacularly wrong for Wilfried Nancy.

I remember scratching my head at his decision to field just three defenders for the visit of league-leaders Hearts.

Not just three defenders, either. An back three comprised entirely of left-footed players, one of whom - Kieran Tierney - is a more natural wing-back.

As for the wing-backs that day? Two forwards whose defensive attributes are not their best qualities: Yang Hyun-Yun and Sebastian Tounekti.

All subsequent selections looked a variation on a theme: players not deployed in their natural, favoured positions in a system the side didn't look like it fully understood.

Celtic were unable to stop conceding goals, which came as no great surprise given the roles players were being asked to fulfil. Luke McCowan as a wing-back. Anthony Ralston as a centre-back.

Wilfried Nancy was apparently not one for round pegs in round holes and it has cost him his job in just over a month.

In fairness to the Frenchman, not having a reliable striker also doomed his system to failure. The amount of glaring chances created but missed was another feature of his short spell in charge.

Celtic podcaster Tino Callaghan has been talking to BBC Radio Scotland in the past 15 minutes and calls the situation at Parkhead a "shambles".

"I was taken aback this afternoon," he said. "I thought if Celtic were going to pull the trigger, it would be after the game on Saturday.

"He's gone now though and the big question is - what next?

"I wonder if Martin O'Neill would step back in. Maybe Shaun Maloney would be more likely. It all depends if the club decide to bring in an interim or permanent manager. It's a shambles.

"A galvanising figure tends to bring everyone on board, but we did that a couple of months ago and now we find ourselves back in this position.

"There's so much going on off and on the park. It's such a crucial decision.

"Nancy's style is so unique and for any system like they to work, you need a full pre-season and a transfer window. It's almost as though he was doomed to fail. It's such a puzzling decision in hindsight."

Former Celtic goalkeeper Craig Gordon has had his say on Wilfried Nancy's dismissal.

The 43-year-old is currently in his second spell at Hearts but spent six years at Parkhead.

The Tynecastle club are six points clear of Celtic and Rangers in the Scottish Premiership table.

“It's a results business," he said. "It's never nice to see anybody lose their job. But from our point of view, it doesn't change anything.

“We'll just concentrate on ourselves. We've got a big job to do up at Dundee. And that's all from Heart's point of view that we'll be focusing on.

“I think whoever comes in, you know the size of Celtic. It's a huge club. They expect to win almost every single match.

“And when that doesn't happen, it's not an enjoyable place to be. For them, it's about starting again. For us, it's just about concentrating on what we've got to do.

“We won't be looking at anybody else outside of our own. We've got a big job to do and that's all we'll focus on.”

While much of the attention is on Wilfried Nancy's exit, many supporters will be just as - if not more - pleased and relieved at Paul Tisdale's departure.

The self-proclaimed "football doctor" was appointed the club's head of football operations in October 2024 and has rarely not been in the firing line.

It's widely believed Nancy was his recommendation, his choice and his appointment, which is why there has been even more attention on the former Exeter City manager... On top of the dreadful summer transfer window he presided over.

It didn't help being caught with his eyes closed when the camera panned to him in Nancy's first game against Hearts.

Its been a collective failure, and Tisdale played a colossal part.

What is interesting is that none of the Celtic squad, as far as I can tell, have posted anything on social media today.

Does silence speak louder than words?

So many people will look at the results of Wilfried Nancy’s tenure as being the reason for his departure. And for the most part they’d be right.

However, the manner of those defeats is what did for him in the end. A stubbornness to play a system his group was not equipped to, defensively passive and meek, while unconvincing in attack.

Leads were surrendered and against Motherwell they were thoroughly outplayed. Nancy relentlessly argued there was progress, but nobody else could see it.

You can only achieve culture change if you take people with you. What Wilfried Nancy was trying to do - significantly alter the side’s style from day one - required a minimum of two things: buy-in from the players and instant results.

The reason the Frenchman is now the shortest serving manager in the long history of the football club is that he clearly had neither.

In the end it all boiled down to yet another massive gamble from those running the club. A 33-day experiment - a grand leap of faith - which blew up in their faces in spectacular fashion.

Nancy wanted to play a certain way, in a certain formation regardless of whether he had players able to turn his vision into a workable reality.

Rather than use what he had to the best of their ability, he tried to shoehorn round pegs into square holes and his defence - using the word loosely - wasn’t able to stop conceding goals.

Nancy was a record-breaker. The first time ever a Celtic manager lost his first two matches, let alone four.

Six defeats from eight games. The opportunity to win the season’s first piece of silverware blown, after the interim-manager had taken care of Rangers in the semis.

Dry January is over for Sir Rod Stewart.

He's off to the boozer to celebrate Wilfried Nancy being relieved of his duties.

He also wants Martin O'Neill back until the end of the season and perhaps Robbie Keane to follow him in the summer.

Someone might want to let Rod know that Celtic aren't playing Dundee at the weekend, though. It's Dundee United.

We now face a scenario where the first four Old Firm games of the season will have be contested by a different pairing of managers for each game. Quite incredible.

1. Russell Martin v Brendan Rodgers
2. Danny Rohl v Martin O'Neill
3. Danny Rohl v Wilfried Nancy
4. (Likely) Danny Rohl v ???

Unless O’Neill comes back.

Or Rodgers...

We’ve never seen anything like it.

As calamitous as Wilfried Nancy's reign was in its own right, it was even worse given Martin O'Neill's uplifting interim stint which proceeded it.

The 73-year-old was brought in to steady the shaking ship Brendan Rodgers hopped off... This vessel has been sinking, though.

Can, and will, the Northern Irishman save the day - and potentially the club's season - again?

I'm sure his phone is buzzing...

It's been a really difficult period for Wilfried Nancy, going in there halfway through a season, losing six of his first eight games. It's a little bit similar to the Ruben Amorim situation at Manchester United but in a shorter period.

Nancy was fixated on changing Celtic’s style, going to 3-4-3, playing in one particular way. He just wasn't adaptable.

One major gripe from fans and pundits alike regarding Wilfried Nancy's short tenure was how he ripped up what was working under Martin O'Neill and tried to implement his 3-4-3 formation and unique tactics without a pre-season.

Players were shoehorned into unfamiliar roles and he didn't adapt, despite admitting before the Old Firm derby that he would ideally have several weeks to teach his players how to play his system.

O'Neill won seven of his eight matches; Nancy won two. Losing the League Cup final in his second week in charge didn't exactly help matters.

Russell Martin lasted 123 days, in comparison...
