Ange Postecoglou's era as Celtic manager is over.

The Aussie came, he saw and he conquered before heading for the bright lights of the English Premier League and north London with Tottenham Hotspur.

The 57-year plundered five out of six trophies during a two year period of total domestic dominance which led to a world record eighth domestic treble.

However, Postecoglou's results in Europe were patchy at best. Although he did guide Celtic back to the top table of European football twice courtesy of winning back-to-back Scottish Premiership titles and gaining automatic entry into the lucrative group stages of the Champions League.

The Greek-born Australian is now off to London with Tottenham Hotspur to embark on another football adventure in the self-proclaimed greatest football league in the world.

The Celtic Way's Tony Haggerty dusts down 10 of the best of 'Angeball' - as it famously became known - and illustrates why the green-and-white-machine never stopped under the Aussie...

Real Betis 4 Celtic 3 (Europa League Group G, September 16, 2021)

It seems strange to start with a loss but it was one that gave the supporters real hope and optimism for the future. Celtic somehow let a two goal lead slip in Seville as the first signs of 'Angeball' are detected.

Postecoglou's men roar 2-0 ahead early with an Albian Ajeti finish and Josip Juranovic penalty but Jota misses a golden chance for a third. That proved crucual as Juanmi's double turns the tie in Betis favour as the Spaniards smash a four-goal blitz in 21 minutes with Juan Miranda and Bruno Iglesias also on target.

Anthony Ralston scores a late header but Celtic could not find a leveller but Postecoglou's side go down to a hugely entertaining but ultimately painful defeat in their opening Group G encounter.

Aberdeen 1 Celtic 2 (Scottish Premiership, October 3, 2021)

Jota's late winner earned Celtic a first away Scottish Premiership victory since February as the supporters grasp Postecoglou to their hearts. The Aussie puts on a real public display of emotion amidst much fist pumping and chest thumping at the end as he bonds superbly with the travelling fans.

It is real adulation and a watershed moment as the Celtic supporters go all in on him as a bossand finally accept him and embrace him as one of their own.

Kyogo Furuhashi superbly chests in a deerved early opener but Lewis Ferguson diverted a corner in after the break for the Reds. Jota's close-range finish earned a long-awaited away win as he seals the victory with six minutes left as Celtic stay six points behind early Premiership pace setters Rangers.

Ferencvaros 2 Celtic 3 (Europa League Group G, November 4, 2021)

Goals by Kyogo, Jota and Liel Abada earn praise from Postecoglou as Celtic secure a priceless 3-2 away win against Ferencvaros to secure European football beyond Christmas.

Celtic remain third in the group just a point behind Real Betis with two games to play and would eventually drop down to the Europa Conference last-16 play-off where they lost to Norwegians Bodo/Glimt.

However Postecoglou's refreshing brand of attacking football is starting to pay dividends and his side show that they can be successful on the European stage. Celtic take their goal tally on the road in the Europa League to 11 in four matches. The win in Budapest is their first away group-stage win since Neil Lennon's men defeated Lazio in Rome two years ago.

Ross County 1 Celtic 2 (Scottish Premiership, November 12, 2021)

Anthony Ralston sparks scenes of utter bedlam and a pitch invasion in Dingwall as he rises to head home a dramatic 97th minute winner against the Highlanders.

It is the epitome of the 'We Never Stop' Celtic mantra that becomes Postecoglou's teams hallmark during his tenure at the club. Stand-in striker Liel Abada had given Celtic the lead only for Jack Baldwin to level on 57 minutes.

Things got worse for the visitors when Carl Starfelt saw red with 11 minutes to go. Just as it looked as though the men in green and white were about to drop six points behind leaders Rangers Ralston produced his last-gasp heroics. It was a pivotal win in the Premiership title race.

Hibernian 1 Celtic 2 (Scottish League Cup final, December 19, 2021)

You never forget your first time. An emotional Postecoglou parades the League Cup as Celtic win the first silverware of his reign by defeating Hibs at Hampden.

Kyogo Furuhashi nets a spectacular double as Celtic come from behind to win the contest. The Japanese forward who was an injury doubt before the game finished smartly to get Celtic level within a minute of them going behind to Paul Hanlon's header.

The Japanese striker then produced an audacious lob for the winner and Postecoglou lifts him up like a proud parent to a son in a wonderful image that is captured for posterity.

Celtic 3 Rangers 0 (Scottish Premiership, February 2, 2022)

In a relentless display of first half attacking football Celtic storm to the Scottish Premiership summit at the expense of a shell-shocked Rangers after a monumental Glasgow derby victory which emphatically ends their rivals' recent derby dominance.

Postecoglou's side blitz their city rivals as a first half brace from the peerless Japanese midfielder Reo Hatate is followed by a third from Liel Abada.

The Aussie endears himself to his adoring public afterwards by declaring: "We’re upholding the values of this football club, not just in terms of winning but the way we play our football. I want them to be proud of us. As I said to the players, we had 60,000 in tonight and I’m sure a lot of them walked in with some problems in their life. For this 95 minutes we made them forget that and feel good and that’s something special.”

Rangers 1 Celtic 2 (Scottish Premiership, April 3, 2022)

One of captain fantastic Callum McGregor's most influential moments in a green and white jersey. Postecoglou's side go deep into enemy territory and come from behind to move six points clear of their rivals at the summit.

The hugely significant win sees Postecoglou's lay one hand on the Premiership trophy as Celtic take a giant stride towards reclaiming the title at the first time of asking.

Aaron Ramsey's third minute opener for the Light Blues is cancelled out inside seven minutes by Tom Rogic's close-range strike, before the leaders took control when Cameron Carter-Vickers rams home the winner.

Celtic 4 Rangers 0 (Scottish Premiership, September 3, 2023)

It's another demolition derby inside Paradise as Celtic beat Rangers 4-0.

David Turnbull adds a fourth as Celtic start piling on the agony and putting on the style and march five points ahead of their rivals at the top of the Scottish Premiership.

Rangers 1 Celtic 2 (Scottish League Cup final, February 26, 2023)

Kyogo becomes Celtic's Hampden hero once again as another clinical brace sees Postecoglou's men retain the Scottish League Cup with a 2-1 victory over Rangers in a thrilling final.

The 28-year-old who also scored twice to secure the silverware last season, returns to the starting line-up after injury to keep Postecoglou's men on course for a domestic treble. It's a sweet victory for the Aussie who returns to the national stadium two months later and defeats them again in the Scottish Cup semi-final.

Postecoglou knew exactly what he was doing by making Kyogo his first ever signing for the club. In the aftermath of the final, Postecoglou declares: "I think you will be surprised how long I am here, I am just consumed by what I do."

Celtic 3 ICT 1 (Scottish Cup final, June 3, 2023)

Postecoglou's Celtic reel off a world record eighth treble and his two year reign of domestic dominance is complete. The Aussie joins Jock Stein, Martin O'Neill, Brendan Rodgers and Neil Lennon on the list of treble-winning Celtic managers.

Goals from Kyogo, Abada and Jota put the seal on the deal on a comfortable 3-1 win over Billy Dodds Highlanders but the silverware success is largely overshadowed by doubts over the Aussie's future.

He refuses to confirm whether he will still be the manager next season with the speculation linking him with Tottenham Hotspur gathering pace.

When he checked at Celtic Park he took the club from 25 points behind Rangers to back-to-back champions and a world record eight domestic treble.

Postecoglou won five out of six trophies and dominated Scottish football. He leaves with his managerial reputation intact and will also go down as a wonderful Celtic manager and revered custodian of the club.

He will be lauded alongside the likes of Stein, O'Neill, Rodgers and Lennon. He leaves behind a managerial legacy of sorts, certainly domestically but not in the European arena.

The debate on whether or not Postecoglou has cemented legendary status within the club after just two years at the helm is a question for every Celtic supporter and their own individual conscience to wrestle with.
