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.
25. Daizen Maeda
Maeda made a perfect first impression on Celtic fans when he scored just four minutes into his debut. Has won eight trophies during his time at club and offers unrivalled energy every time he steps on the park. Won the SFWA Player of the Year award last season. Cost a reported fee of just £1.3 million, which is sensational value. | SNS Group Photo: Craig Williamson - SNS Group
26. Matt O'Riley
Signed from English League One side MK Dons for £1.5 million, the Danish international left the club for £26million to Brighton last season having won everything. Unplayable during the 2023/24 season, O'Riley scored 18 goals from midfield and assisted a further 13. His move to Brighton has yet to work out for him, though, and he's currently out on loan to Marseille in France. | Getty Images Photo: Getty Images
27. Kyogo Furuhashi
Choosing Ange's best signing was always going to prove a tough task, but it is almost impossible to look beyond the signing of Kyogo. The Japanese striker is a cult hero at Celtic and has scored 82 goals in three-and-a-half seasons for the club. Costing just £4.5million, and sold for £10million Kyogo was an outstanding piece of business by big Ange. Currently at Birmingham City, he has struggled since departing Celtic, and hasn't scored a league goal in almost a year. | SNS Group Photo: Ross Parker - SNS Group
