The affable Australian, brought in by owner Evangelos Marinakis to replace Nuno Espirito Santo on September 9, is already hanging on to his job by the coat-tails.
That's despite Marinakis' ringing endorsement of the appointment.
Forest's ringing endorsement of Postecoglou
“We are bringing a coach to the club who has a proven and consistent record of winning trophies," he was quoted as saying at the time.
"His experience of coaching teams at the highest level, along with his desire to build something special with us at Forest, makes him a fantastic person to help us on our journey and achieve consistently all our ambitions."
And yet, just 27 days later, there are genuine question marks over his suitability in the role owing to the fact that he's yet to win a match.
A 3-0 loss in his opening fixture at Arsenal wasn't really a surprise, but a 3-2 loss at Swansea in the Carabao Cup a few days later - despite being 2-0 up at one point and still leading 2-1 going into second-half stoppage time - saw eyebrows raised.
A 1-1 draw with Burnley at Turf Moor would normally be seen as a creditable point, but another opportunity missed to grab all three heaped further pressure on the manager.
A late goal from Antony salvaged a 2-2 draw for Real Betis in the Europa League before an incredibly disappointing home reverse against Sunderland and another in Europe (2-3) vs Midtjylland.
Will Newcastle game be Postecoglou's last?
Newcastle away was never likely to be the game in which Postecoglou broke his duck, and the subsequent 2-0 loss brought up a record of P7 W0 D2 L5.
What makes it even worse is that in the Premier League only (since the Australian took over), Forest are 20th of 20 teams in terms of goals scored (one), losses (three), points (one), clean sheets (zero), errors leading to shots (five) and shot conversion rate (2%).
They're only one place better off for goals conceded from set-pieces (four) and shots on target faced (22).
The question that really needs to be asked, however, is whether Forest would be showing their worst side if they were to dispense with Postecoglou's services during the international break.
27 days and counting...
At the time of writing, he is still three days away from the record of the quickest managerial tenure in Premier League history, which is currently held by Sam Allardyce when he attempted to keep Leeds up in the top flight in May 2023 and failed.
In the space of 30 days, he'd been and gone out of Elland Road. Les Reed's 40-day tenure at Charlton between November and December 2006 is the next quickest, though he at least amassed four points in that time.
It's clearly regrettable that the Australian hasn't been able to get things right straight off the bat, but to be considering sacking a manager less than four weeks into a rebuilding job is surely an indication of how short-sighted the club are being.
Is Marinakis' ego to blame for Forest's problems?
That's particularly the case given the wording in the initial announcement of his appointment:
"His desire to build something special with us at Forest, makes him a fantastic person to help us on our journey."
Does Marinakis genuinely believe then that within 27 days, Postecoglou has gone from being "a fantastic person" to persona non grata?
Isn't this potential culling of a progressive and forward-thinking manager who needs time - and money - to shape things as he would like more of a reflection of Marinakis' ego?
An ego which saw the outrageous behaviour last season when the owner walked onto the pitch to berate Nuno.
Who would replace Postecoglou?
Whilst it's clear that Forest can't contemplate going down - and were the status quo to continue for some while, there would be a genuine cause for concern - Postecoglou hasn't yet been given a single transfer window to bring in his own players.
He is trying to make the best of what he has with players who, it's largely forgotten, ended up getting Nuno the sack because they weren't performing.
In May 2025, for example, Forest lost to Chelsea, West Ham and Brentford, and drew with Leicester and Crystal Palace.
Were Marinakis to bow to public opinion and fire the Australian, has he thought about who he would bring in? And who would want to come to a club with an owner who has such a trigger finger?
Ange remaining philosophical
From the manager's point of view, he remains philosophical.
"It is a struggle, it is a fight, it is what we do. It does not worry me, that is why I love what I do," he said after the Newcastle defeat.
“If people want to make an assessment on me after three and a half weeks, there is nothing I can do about that. I had the option to have been sitting on a couch watching the game today and not been in the middle of it. I would much rather be here. I love a fight."
One way or the other, a fight is exactly what's awaiting Postecoglou now...
