Approximately four years and four months ago, Ange Postecoglou was named as the head coach of Celtic and tasked with restoring the Hoops place at the top of Scottish Premiership.
Appointed on 10 June 2021, the Australian boss entered the Celtic Park doors with the club in the midst of a crisis. Rangers had won the league in invincible fashion and a protracted move to install Eddie Howe as their new boss has fallen at the final hurdle. Big Ange - as he came to be known - was a supposed ‘second choice’. The rest, as they say, is history.
His success ultimately saw him poached by Tottenham Hotspur, where he went on to win the Europa League last trophy last summer before being sacked by the North London outfit the following week. A short stint at Nottingham Forest would follow, where he last just 39 days before being shown the door.
Linked to the vacant role at Celtic Park earlier in the week, following the resignation of Brendan Rodgers, there a plenty of supporters who would welcome his return, with many believing the bulk of his success in Glasgow came from his ability to spot talent and recruit them into a system which was very much his own.
But who were his best signings during his tenure at the club? With Kyogo Furuhashi, Matt O’Riley and Jota making huge improvements to Celtic during his time as head coach, it is hard to pick his best buy. However, here at The Scotsman, we tried our best to do so.
These are the 27 Celtic signing made during Postecoglou’s time at the club, ranked from worst to best.
21. Joe Hart
Previously one of the best goalkeepers in Europe, Hart had faded into the background at West Ham United and Tottenham Hotspur before he was picked up on a free by Postecoglou. Retiring after the 1-0 Scottish Cup final win over Rangers in May 2024, the ex-England international was a player that lifted trophy after trophy and formed a real bond with the fans.

22. Alistair Johnston
Juranovic's departure to Berlin paved the way for the Canadian's transfer to Glasgow - and he's proven to be an upgrade on his predecessor. The Celtic star has made the right-back position his own since joining from CF Montreal on a five-year deal. One of Postecoglou's best signings. | SNS Group Photo: Craig Williamson - SNS Group
23. Jota
Jota was a key part of Celtic’s success under Postecoglou, firstly on loan from Benfica and then as a permanent £7m addition. Paid back that fee and move when he made a surprise £25m move to the Saudi Pro League last summer, but struggled for game time. Found his way back to Celtic in January via Rennes, where he started to show some of the form he had during his first stint at the club before being struck down by an ACL injury in April. | Getty Images Photo: Getty Images
24. Cameron Carter-Vickers
A colossus in defence, the American has found a home in Glasgow and has been pound for pound the best centre-back in the Scottish Premiership since his arrival. Originally arriving on loan, the 26-year-old joined permanently for a reported fee of around £6 million, but he would be worth at least triple that amount if he was to be sold on now. | Getty Images Photo: Getty Images
