Having already become the first Celtic manager to lose his first two games in charge, Nancy, who previously head coach of Columbus Crew in Major League Soccer, has now become the first since the legendary Jock Stein in 1978 to lose four games in a row.
It appears the majority of Celtic fans can see no way back for the Frenchman, with parallels being drawn with Russell Martin's ill-fated shot spell in charge of city rivals Rangers this season and unfavourable comparisons to interim manager Martin O'Neill.
George: Does Wilfred Nancy have any understanding of the Celtic fans and their expectations? They are not stupid, but saying there are improvements with the team performance is just condescending to say the least. I just hope the pain doesn't continue for too long for the fans.
George: Listening to Wilfred Nancy is depressing. How is this an improvement? Sad to see this happening to Celtic - embarrassing.
George: As a neutral, I've listened to Nancy's post-match interviews and all I can think about is Eric Cantona's seagulls and sardine trawlers speach. Absolute nonsensical.
Hugh: Did the Celtic manager spout all these nonsense phrases at the recruitment interview and the board sat back saying this sounds amazing? Time for manager to go and recruitment and board to be cleared out.
Matt: He says we lost the game in three minutes? Must've been the three minutes it took someone to decide on his appointment. What a mess.
Toby: It wasn't "three minutes". It was a poor manager who doesn't know how to take responsibility for his team. He better be sacked!
Ross: This is lunacy of the highest order from the people in power at Celtic. What top team in Europe is playing 3-4-3, let alone any team in Scotland? Why do they think it would work? Only because one of their mates on the otherside of the world was having limited success with it.
Kevin: Wilfried, I hope you read this. You have a pool of players worth 10 times that of the majority of the rest of the Scottish Premiership. We don't need your madcap arrogant tactics of failure and promises of tomorrow. You are being shown up by managers who understand how to play tactically to their resource strengths. Go somewhere else if they will have you.
WottsamattaU: These fans saying these players aren't good enough. Just over 10 days ago, they'd won seen out of under under Martin O'Neill, including their firsst win away in Europe for 20 years. Bullying directors who've never played football are the problem but don't care as long as their bonuses are paid every week on the millions in the bank. Nancy is a cheap option - manager from MLS saving money yet again. He's worse than Russell Martin, but directors won't kick him out like Rangers did because that would confirm they were wrong. Celtic won't win anything under Nancy with his Connect 4 board game, but the directors know Celtic fans will turn up to watch the grass grow.
James: I'll stick up for MLS here, seeing as how it seems to be a fun topic to look down on it. That is a league miles above ours in terms of quality and finances. The Celtic job is to Nancy what the Rangers job was to Martin - too big for him.
Harry: What on earth were this club (not one that I support) doing appointing this man who is without top-league managerial experience? I know Martin O'Neill didn't want a longer-term commitment, but given his experience and managerial career, why didn't they try to keep him until the end of the current season?
John: Goodbye Lawwell. Now goodbye Nancy. Get this idiot out now. He is destroying our club. I cannot take any more of this. This is breaking my heart to see my famous club in tatters. He's destroying my Christmas.
Dave: Sorry, the manager has to go. Never mind sticking with your man, you cannot give him transfer money to spend.
Kevin: Nancy has lost the dressing-room. No way back. He must go now. Bring back O'Neill for the rest of the season and take stock. The board must accept they messed up and we move on.
Sndrew: Martin O'Neill won seven of eight. Nancy has lost every game. Is that the players? Or the coach?
Gary: Nancy is Celtic's Russell Martin. The similarities are incredible and the end is also gonna be similar.
Tim: Bring back Martin O'Neill - only solution. Yer man from USA is never gonna work. Three at the back didn't work at Manchester United and won't work at Celtic. Wise up.
Hugh: How can the players be blamed when they haven't a clue what the manager is trying to do? The same players won seven out of eight and would do so again with Martin O'Neill at the helm.
Dan: I think Celtic need to think about getting an interim manager in to steady the ship before matters get worse. Martin O'Neill anyone?
James: Nancy must go. Hasn't got a clue. Bring Martin O'Neill back before it's too late. Lost four games, 10 goals against, three for, says it all.
Mark: Why, oh why did the Celtic board not cancel the appointment of Nancy when they could see what an amazing job Martin O'Neill was doing? Only makes the situation worse when O'Neill disclosed on media he would have stayed. MLS is not the same and Nancy has no proven experience at this level. Simple answer - get O'Neill back and make it a permanent contract.
Sul: Don't think Martin O'Neill has unpacked yet. Good job, as he may be needed soon again.
Gus: I would normally say give a new manager time. But Martin O'Neill managed to give an average squad an edge. It's hubris from Nancy to change everything that O'Neill achieved in his first games and expect success. Sack Nancy and beg O'Neill to come back for the rest of the season. It's the only way forward.
Billy: We have went from being in a fairly comfortable position to a salvage job. This is not the time to bring in an idealist who looks completely out of his depth. How long will the board leave it before they act? Maybe they will wait until we are in third place and too far behind. Tough decisions have to be made before it's too late.
Hugh: I just hope Martin O'Neill is on a plane from London to Glasgow just now.
Matt: I'm really hoping for a "Sacked In The Morning" episode on BBC with Wilfried Nancy. It'd be box office stuff.
