Despite the Australian landing Spurs' first trophy of any description in 17 years, his 'reward' was being told to pack his bags by chairman, Daniel Levy, a decision that's left Micky van de Ven baffled.
Strange decision to sack Ange
"I think many of the players got along with him (Postecoglou) well, and of course he is the first coach who has brought success to Spurs in a long time," he told reporters after a recent Netherlands game.
"That also shows that he has a certain quality. That also means that he has a winning mentality, 100%. From that, you would of course say that it is strange that he was fired."
Strange indeed.
The Dutchman's injury, along with those of many of his teammates, undoubtedly contributed to Tottenham's poor season in 2024/25, where they had a below-par win percentage of just 35.6% in all competitions.
If Levy can't accept the extenuating circumstances of last season and just sees them as an excuse, it says more about the chairman than his manager.
Postecoglou brought a recognisable style to Spurs
Take the best players out of any team and the effect is exactly the same, but at least Postecoglou can go with his head held high. The Europa League triumph can never be taken away from him or his players.
37 defeats as well as 37 wins from his 86 games in charge is ultimately what Levy will have based his decision on. 139 goals conceded is likely to have played a part too.
No matter that Postecoglou brought a recognisable way of playing back to the blue and white half of north London.
Frank has certainly made his mark over in west London, with his Brentford side consistently confounding the critics.
Despite having one of the smaller budgets in the Premier League, and having sold one of their best players recently in Ivan Toney, the Dane still seems to be able to get the maximum out of his Bees squad.
However, in the four seasons they've been in the English top-flight, Brentford have never finished higher than ninth (24/25 - 10th, 2023/24 - 16th, 2022/23 - 9th and 2021/22 - 13th), which begs the question as to whether he really is the right man to replace Postecoglou.
Brentford's results haven't been great
In the same two season period as the now former Spurs manager, Frank also lost on 37 occasions but won just 28 games.
The 134 goals that Brentford conceded was only five less than the Lilywhites, whilst the 132 goals that Brentford scored across 23/24 and 24/25 is 21 less (153) than Ange's side managed.
Though Frank's win percentage in 24/25 was 41.9%, so better than Postecoglou's, last season it was just 23.8% compared to Spurs' 51.2%.
With the greatest of respect to the Dane, Brentford and Brondby too, he's never managed in the Champions League or at what could be termed a 'big' club.
He comes across well in interviews and it's clear he can manage big personalities, but is he really that much better than the last few managers that Daniel Levy has hired and fired?
A further issue is which backroom staff he brings with him.
It's understood that Justin Cochrane's name has cropped up during talks over the position, a man who is currently part of Thomas Tuchel's set-up with England.
After the recent debacles against Andorra and Senegal, that's hardly an exciting appointment either, should Cochrane continue to form part of the negotiations.
Frank finds life "easy" at Brentford
In a recent interview, Frank noted that; "I think that there's a part of me that thinks that, one day, maybe I need to try something different. Is that a bigger club, Champions League, different challenge? I don't know."
He also went on to say that he likes his social life and doing things away from Brentford, and having built things up at the club including the processes and ways of working, it was "easy" compared to having to effectively start again somewhere else.
At the time of the interview, weighing up the two options was clearly something on his mind, but with the Tottenham opportunity being placed in front of him, it's seems that Frank has decided the time is right to move on.
Having the ambition to do well is all well and good of course, but if Postecoglou's 23 home wins and 14 away wins wasn't good enough, Frank's 15 home wins and 13 away wins in the same period certainly isn't going to fill the Tottenham faithful with too much confidence.
Déja vù in two year's time?
As with many who have recently gone before him, the Dane really has to hit the ground running if he wants to get the home support onside, perhaps more so in light of the European title.
He only need look at Postecoglou's two years to see how quickly things could turn sour too. The Australian had his name sung heartily in the first months of his tenure as the football played was of the highest standard, and yet, when the injuries kicked in and results went south, fans wasted no time in letting him know about it.
That supporter backlash is precisely what Frank has to guard against or else Daniel Levy and Tottenham will once again be scouring the market for another manager 24 months from now.
