With the "sacked by Christmas" chants and comments having aged like milk, the green half of Glasgow is in full party mode. Let's not sugar-coat it, there are plenty in that green camp who were outraged when Ange Postecoglou was appointed Celtic manager just under a year ago.
It all just serves to highlight what an incredible job Postecoglou has done in such a short space of time. The last time an unknown manager plying his trade in Japan was announced as the new gaffer for a big club, a team of 'Invincibles' was the result.
While it's still far too early to compare 'Big Ange' to Arsene Wenger, they do share similar traits, and now history. Both were unheard of and immediately set about making change at clubs that had stagnated.
It's extremely tempting to go into great detail about how Australia's newest cult hero made the world sit up and take notice, particularly as his former charges in the national team flounder and look set to miss out on this year's World Cup.
But much like the man himself, thoughts turn to what's next. All the great coaches in world sport have that mentality, they enjoy the moment but then it's back to business. Ange is no exception, his mind is undoubtedly already on next season.
Postecoglou is not a man to sit back and admire his trophy collection or personal accolades, his mission in life is centred around one thing; delivering bold, daring, attacking football that puts bums in seats.
So what, realistically could he do next?
England
Whether or not there's any weight behind the talk that Postecoglou has been turning heads in England, there's no doubt that he has at least been noticed.
With Leeds having lost their cult hero manager in Marcelo Bielsa earlier this season, not to mention playing a similar style to 'Ange-ball', there's an argument that a move to Elland Road would be a perfect fit.
The English game is almost tailor-made for the style that Ange demands of his players, the high-pressing, explosive and attacking sort of chaos that you can't take your eyes off.
The days of parking buses are all but gone in the Premier League, Jurgen Klopp and Pep Guardiola have seen to that. Postecoglou would likely feel right at home.
It's hard not to imagine that this is his final destination, but it's not time for him yet, he has other mountains to climb first.
Europe
There's no doubting he would do well in most parts of Europe, all great managers do. The lure of going back to the continent that is so far the scene of his only failure in management would be hard to resist.
Plenty there would still doubt him as well, something he doesn't take personally, but views he would love to correct nonetheless. Part of Postecoglou's appeal to Australians is his burning desire to prove that his home country can play against the best.
It may not be a chip on his shoulder per se, but it's certainly a point he wants to prove.
With all of that said, and while there's no doubt he'll find himself there one day, it still feels as though Europe is a stop further down the line.
Celtic
Stopping short of a once-in-a-lifetime offer at one of the top 10 clubs in the world, 'Big Ange' will stay at Celtic and look to cement his legacy.
The curdled claims of "sacked by Christmas" have now been thrown in the bin but Postecoglou is nowhere near finished with his Celtic project. Having proved his detractors wrong, he will now be intent on serving up something sweet following their main of humble pie.
There are loan deals for Jota and Cameron Carter-Vickers that will either need to be turned into buys or for which have replacements need to be found. The squad will again need to be strengthened and Ange will use his knowledge of the Asian market to again steal a march on his rivals.
He will also be acutely aware that Rangers are still very close in his rear-view mirror. Giovanni Van Bronkhorst has done an exceptional job since taking over from Steven Gerrard mid-season.
Rangers now find themselves in the Europe League final, a massive achievement considering the teams they have come up against. They will see a windfall from this and use it to reload for another tilt at the Scottish title.
Postecoglou doesn't want to be a one-hit-wonder, he wants to prove it was no fluke and win the league again. Doing that would solidify his reputation and leave little doubt that he is the real deal.
The Final Frontier
The biggest carrot of them all. European Champions League football is the benchmark and the dream for any club manager. Having already managed at a World Cup, Ange has this one last box to tick.
His squad came up embarrassingly short against Bayer Leverkusen in the first half of this season, he will have been stung but not deterred.
With the expulsion of the Russian clubs from Europe following the situation in Ukraine, Celtic now have an automatic place in the Champions League for next season.
The continent that still doubts will see him return and Ange will get another chance at silencing the naysayers. It might be fanciful but history suggests it would be brave to bet against him.
