Like Lubo Moravcik and Henrik Larsson, Ange Postecoglou will find himself bracketed among the greatest Celtic bargains in the club’s history.
Another unknown who arrived to some bemused reaction, Postecoglou was quick to pour cold water on the doubters. And then some.
If management requires the skills of a diplomat, few could say that the Greek Australian has put a foot wrong.
Back-to-back league titles assured and a treble within touching distance, Postecoglou’s we-never-stop mantra will be put to the test across the closing weeks of the campaign.
The highest points total in the history of Scottish football remains a plausible return for this season’s work; victories from their remaining games would give them 107 points, eclipsing the 106 of Brendan Rodgers’ Invincibles.
And, with 105 goals scored so far this Celtic team could make another little bit of history should they surpass the 116 haul that goes back to 1916 as the Parkhead side’s optimum haul.
It is a form that has not gone unnoticed elsewhere.
West Ham’s Karren Brady is the latest to take note of Postecoglou with comments suggesting that he would make an impact in the English Premier League.
She joins a list of clubs – nine to date this season – who have loosely been linked with the Celtic manager.
Parkhead fans will be wary of the pull of the Premiership and the riches it offered but there has been little about Postecoglou’s body language or tone in recent months to suggest he could be enticed to pastures new.
With the significant carrot of Champions League football secured, there is a strong suspicion that this is where Celtic and Postecoglou’s next challenge lies.
