Indeed, Monday’s 2-2 draw against their Old Firm rivals ensured that the Bhoys remained nine points clear at the top of the table, with the Premiership crown very much being the Hoops’ to lose at present.
As such, the Celtic manager will undoubtedly be hoping that his side can continue their remarkable run against Derek McInnes’ ninth-placed Kilmarnock outfit at Parkhead this afternoon.
However, with a number of injury concerns to deal with ahead of the fixture, Postecoglou may well be forced into something of a shakeup in his starting XI against Killie.
How many changes will the 57-year-old make to the team which started at Ibrox last time out? Here’s how we at Football FanCast think Celtic could line up, as well as the latest team and injury news.
Predicted Celtic XI: Hart; Johnston, Carter-Vickers, Starfelt, Bernabei; McGregor, Mooy, Hatate; Abada, Kyogo, Jota.
With Sead Haksabanovic, Stephen Welsh, James McCarthy and Greg Taylor all ruled out as a result of injury, we predict that Postecoglou will make four changes to the side which lined up against Rangers last Monday.
The first of these alterations come at the back, with the aforementioned Taylor dropping out of the XI as a result of a hamstring strain picked up against the Light Blues, and the “exciting” – in the manager’s own words – £3.75m summer signing Alexandro Bernabei being handed just his sixth Premiership start at left-back.
The rest of the back five remains unchanged, with Joe Hart starting in goal, Alistair Johnston retaining his place at right-back and Cameron Carter-Vickers and Carl Starfelt being given the nod in the heart of the Hoops’ defence.
In the middle of the park, despite having featured in every league game so far this season, after a couple of below-par performances in recent weeks, Matt O’Riley – dubbed the “best player in Scotland” by one Celtic source – drops out of the XI, with Aaron Mooy being handed an opportunity to impress alongside Callum McGregor and Reo Hatate in the midfield three.
The final two changes come in the attacking trio, with both James Forrest – who was rather quiet against Rangers – and Daizen Maeda making way, while Liel Abada and Jota return to the starting XI, with Kyogo Furuhashi keeping his place up top.
