Ole Gunnar Solskjaer faces the toughest period of his Manchester United career so far as the calls for his sacking intensified following their humiliating 5-0 home defeat to Liverpool on Sunday.
The Norwegian has faced pressure in the past, but nothing like this as his team were put to the sword in their biggest game of the season - with Jurgen Klopp's men racing into a 4-0 lead at the break.
Pundits have been having their say on Solskjaer's future all season long, with United guilty of some poor results before their hammering at the hands of Liverpool.
But the manner of the latest defeat has left even the most conservative of pundits admitting his time could soon be up.
Sportsmail examines the views of football's biggest pundits and what they think should be done on the future of Solskjaer.
STAY
Gary Neville
By far Solskjaer's biggest cheerleader having played alongside him, Neville has not been afraid of criticising the Norwegian this season but has stopped short of calling for his sacking, saying he will never demand for any manager to lose his job.
Before the Liverpool thrashing, Neville was adamant that he would not give into pressure from fans and suggest that Solskjaer deserved to be sacked.
'I've got Manchester United fans on my social media all of the time saying, "Gary, he's your mate. You won't call him out,"' he told Sky Sports last week.
'No, I won't. I won't call Steve Kean out, or Arsene Wenger at Arsenal. I'm not going to come on this show 11 years later and ask for a manager to be sacked. It's never going to happen. He's a club legend. He's my team-mate. I actually like him a lot.
'Manchester United have failed with two previous managers who have been world class. I think they persist until the end of the season.'
After witnessing United fall apart against Liverpool, Neville was thrown into a back and forth debate with fellow pundit Jamie Carragher over his defence of Solskjaer as he refused to change his view and insists the club will 'hold their nerve' due to the current ownership set-up.
'If this was in the immediate post-Sir Alex Ferguson era, Ole would be under massive pressure tonight,' he added after the clash at Old Trafford.
'But I think the club will hold their nerve. I don't think they have planned for a new manager this season. I think they will sit with him until the end of the season. There will be a massive outcry from fans and media that Ole should be sacked and I can understand that after that game. It was a monstrously bad day and it takes some recovery from.
'But I think this club is a lot more stable in terms of the ownership - I think now might be the time for them to communicate with the fans if they are going to back the manager for the next six to eight months, which I think they will.
'They have said they believe in the projects even though there will be some bumps. Ole says they are close. I am not convinced because I look at those players and the other teams are really good and Man Utd are nowhere near as good. I want to see a structured, organised performance. I believe the club are stable and will not sack the manager but they have to get back on the bike.'
Bryan Robson
Unlike Neville, former Manchester United midfielder Bryan Robson never played alongside Solskjaer but stressed it was 'not the time' to swing the axe on the boss.
The former Red Devils captain admitted the result against Liverpool was 'embarrassing' but pointed out that making a change wouldn't necessarily work and that there were a lack of suitable alternatives.
'This was embarrassing but you can't say it hasn't been coming,' he said in his column for Sportsmail.
'The pressing game that United have tried to adopt just isn't working. The players are not adjusting to whatever Ole is asking them to do and the system needs to change.
'The best performances from this team in recent seasons have come from being compact, strong defensively and hitting teams on the counter attack.
'But it's not the time to sack Ole. I do believe he will keep his job. It's easy to clamour for the manager to go after such a painful defeat but change now causes more upheaval.
'The club have found that changes every couple of years just don't work and who do you replace him with? I'm not sure there's a candidate who can make such a significant difference without causing major disruption again.'
GO
Jamie Carragher
Liverpool legend Carragher had cutting words for Solskjaer in the build up to the game with his old side - saying United needed a 'better manager', although the Norwegian dismissed it as mind games to help his beloved Reds win.
But speaking after the 5-0 loss, Carragher bickered with Neville about Solskjaer and reiterated his view and said he honestly felt that Solskjaer - while praising the job he had done so far - was 'not good enough' for the Man United post.
'I think Ole has done a good job but to take on Klopp, Tuchel and Pep, Manchester United need a better manager,' he told Sky Sports.
'I wasn't saying that on Monday in a disrespectful way, I feel for Ole - that will be the darkest day in his career.
'I don't want to get involved in a slanging match, I know Ole said something back and rightly so.
'I'm not comfortable saying someone should be sacked - but we are comfortable saying Fred is not good enough or Scott McTominay is not good enough so I do not feel too bad saying Ole Gunnar Solskjaer is not good enough.
'Manchester United should have the best in class - the best managers and coaches in the world. If you have Ole as the manager you should have someone like Carlos Queiroz as the assistant coach.
'You cannot have people learning on the job who have never been at the club of that size. They have got Mike Phelan but I do not think he's a coach, there's Michael Carrick and Kieren McKenna, they have never coached anyone in their lives.
'You have got to have someone who has been there and done it. You cannot be learning on the job at Manchester United.'
Chris Sutton
Former Blackburn and Celtic striker Chris Sutton believes Solskjaer has run out of time to prove he still has the quality to lead United to silverware and said it was a matter of time before he was axed.
Sutton has previously been downbeat on United's chances of challenging for the title and believes the signing of Cristiano Ronaldo has hindered the team, and now thinks Solskjaer is on the chopping block after failing to produce with three high profile signings given to him this summer.
'We've stuck up for Ole Gunnar Solskjaer but he's been there for almost three years now,' Sportsmail's Sutton told BBC Radio 5Live.
'And with the signings at the start of the season you were thinking they have to challenge for the title, but I really don't see any other way. He has to go, surely?'
Micah Richards
Another Sportsmail columnist in Micah Richards, who played for United's bitter rivals Man City for many years, was reluctant to say Solskjaer should be sacked but admitted he looked 'out of his depth' after the Liverpool defeat.
He suggested the club will soon be forced to make a decision on Solskjaer's future if things did not continue but urged United to take action either way.
'He has such a legendary status at the club so it was always going to be difficult when things come to this,' Richards said.
'It has to be down to the coaching and some of the things were ridiculous, basic mistakes. They don't know when to press or when to drop deep and it looks like Ole does not know what to do.
'They need to back him and say he will go to the end of the season or bring someone else in.
'I feel sorry for him, looking at a person who has this legendary status but he looks a bit out of his depth. If that can't be resolved they need to move forward.'
Jason Cundy
The talkSPORT host and former Chelsea defender had already called for Solskjaer's sacking last month after suffering a 2-1 defeat against Young Boys, with the unfancied Swiss outfit scoring in stoppage time in their Champions League match-up.
Cundy did not hold back on Solskjaer and his tactics, calling him 'clueless' and questioning why he failed to make changes after going down to 10 men, despite the opposition tinkering with their system.
'That there shows he's utterly clueless,' Cundy told talkSPORT.
'That performance, the team shape… they went down to 10 men, yes, but come on. They went to five at the back and he didn't change it.
'They were getting overrun in the middle of the park. Poor Fred, Paul Pogba and Bruno Fernandes. I've got so much sympathy for them, they had no help, they were getting passed around.'
Cundy said he would pull the trigger now if he was on the Manchester United board and suggested former Chelsea boss Antonio Conte as a successor.
'It exposed Ole, it did badly. I'd sack him. We know what's coming, don't we? You've got Antonio Conte out there…
'Who's the better manager? There will be a stage in the season where they'll be like "I wish we did it earlier".
On the fence
Paul Merson
Former Arsenal midfielder and Sky Sports pundit Paul Merson took issue with Solskjaer after their defeat to Young Boys last month and insisted that Chelsea boss Thomas Tuchel, Man City boss Pep Guardiola or even former United boss Jose Mourinho would have won the game.
He didn't call for his sacking but believes Solskjaer lacks the ability to make big calls in pivotal games.
'This is why the jury's out on Solskjaer. Seven defeats in their last 11 Champions League games, that's a phenomenal record.
'He panicked. If I put Tuchel in charge there, Guardiola or Mourinho, Man United do not lose that game. Man United win that game.'
Merson was left baffled by Solskjaer's failure to introduce Mason Greenwood and accused him of 'people pleasing' after the arrival of Ronaldo at Old Trafford.
'Greenwood is on the bench, he has to come. I'm not even a manager anymore, and I know that. If I know that, why doesn't he know that?
'I worry, because it seemed to me it was people pleasing. He kept Ronaldo on for a long, long time in the game. Put Greenwood up front and you can counter attack.
'Man United have not been playing well. They should have got well beaten at Wolves.
'Against Newcastle last week, at 1-1, it was heads or tails. And then they go and get beaten by a pub team in Champions League football terms.
'You've got to be tactically good enough to say "right, I need to change things".'
Peter Crouch
Sportsmail's Peter Crouch, who went up against Solskjaer in his Liverpool days, also made the comparison between the Norwegian and his managerial rivals Tuchel, Guardiola and Klopp, insisting United would 'work harder' if any of those three were in charge.
Just like Merson, he claimed Solskjaer was afraid to 'upset players' and said the team lacked a manager who was going to be strict and haul people off when showing a poor attitude.
'I think if Pep and Klopp are in charge of this (United) team, I think the front four would work a lot harder, no way they would get away with it,' Crouch told BT Sport. 'Don't think Ole will upset players.'
'I see body language on some players that under Pep and Klopp they would be hauled off. Arms thrown recently, that I don't like, needs to be nipped in the bud, those two would have made sure it was.
'David Silva and Kevin De Bruyne were the two hardest working players when City pumped us in a game a while back, I don't see that at United.'
'Ole has come from Cardiff and Molde, managing Manchester United, unfortunately they do not have a manager of the experience of Pep, Tuchel, and Klopp.'
Paul Scholes
He is never afraid of giving his opinion or a stinging attack on his former side United but Scholes has so far resisted the opportunity to call for his old team-mate's head.
Scholes believes Solskjaer can turn United's fortunes around but said he would have to take responsibility for the Liverpool thrashing and admitted the team's set up for the match was 'not quite right'.
'It was a humiliating day for everyone involved with the club: the fans especially, the players worse I suppose and the manager worst of all.
'He will feel responsible for that. To be fair, I think when you're playing against a team like Liverpool, the way the team was set up wasn't quite right.'
The legendary midfielder said Solskjaer's only hope was to keep fighting and find a way to 'galvanise' the team, starting with the next trip to Spurs.
'Can he turn it around? I hope so. We played with Ole for years and he's a resolute character.
'He came out fighting and at the end of the day it's only three points. You don't get anything more, you don't get anything less.
'It's a little bit embarrassing but now he's got to try and galvanise the team and try and find a way forward.'
