Postecoglou, for all his faults, has managed to reignite the burning flame in the Tottenham faithful during his time in north London. They were treading on the path to revolt and apathy by the time he was appointed as head coach.
With the Australian came the promise of change, and he has sought to deliver that in every sense. Spurs have one of the most recognisable and entertaining styles in world football, which was much craved following on from the conservative philosophies of his predecessors. His gift of the gab and ability to perfectly articulate his vision for a better tomorrow would make him an excellent propagandist in another life, his every word hung on and believed, the will to run through brick walls for him only strengthened.
The unavoidable downside has been results, particularly those since the end of Tottenham's purple patch to begin 2023-24. Postecoglou has lost 19 of his 56 Premier League matches and is averaging 1.62 points a game, which translates to 61.6 per season - usually a tally seen among sides finishing sixth to eighth.
This comes back to Pochettino's prior warning, one that Spurs fans have become all too familiar with in the years after his departure. The painful rebuild. It's a term Postecoglou himself has paraphrased, stressing projects don't come to fruition overnight.
The club took that a little too literally over the summer, however. Postecoglou's only additions were teenagers Archie Gray, Wilson Odobert and January recruit Lucas Bergvall, plus the renewal of Timo Werner's loan and the club-record £65m acquisition of Dominic Solanke.
The makeup of their business matters a lot, particularly as the club insisted they want to compete immediately and not only in the future. Heading into the summer, most of Postecoglou's key targets were in the Solanke mould of Premier League-ready players who would improve the team, though weren't beyond the club's stature by any means or the 30-something year olds that Mourinho and Conte wanted.
Conor Gallagher had been earmarked since last summer, but Chelsea agreed to sell him at a lower rate to Atletico Madrid instead. Out wide, Pedro Neto and Eberechi Eze were the 'dribbly wingers' who were more ideal tactical fits than Spurs' other wide-men, though deals weren't agreed for either. Tottenham also needed homegrown backups in defence, with free agents Tosin Adarabioyo and Lloyd Kelly first touted a year ago. They chose to join Chelsea and Newcastle respectively.
Postecoglou has been tasked with putting together an unready team incapable of matching the physical or tactical demands of his philosophy week after week, and so Spurs are riddled with consistency. Of course, the manager is responsible for tactical decisions and selections - for starters, they shouldn't be giving up chances at a rate as if they're handing them out like free samples - but the club's new footballing structure, headed by chief football officer Scott Munn and sporting director Johan Lange, have indeed left him short.
