The more things change, the more things stay the same.

It took a crucial 97th-minute winner from Anthony Ralston in December last season to kick-start Celtic's Premiership title charge.

It was deja vu in Dingwall as German debutant Moritz Jenz headed home seven minutes from time to ensure the champions beat Ross County this time too.

Ange Postecoglou's men made it three league wins out of three under the Aussie on their last three trips to face the Staggies in the Highlands.

Celtic have come out the blocks faster than they did last season and, although they are not quite firing on all cylinders yet, they are still doing enough and the whole first-team squad is contributing.

Before kick-off Postecoglou was forced to chop and change his line-up from last weekend as Jenz surprisingly came in for his competitive debut at the expense of last weekend's opening scorer Stephen Welsh and David Turnbull replaced the injured Reo Hatate in midfield.

It was as you were everywhere else on the pitch with Kyogo Furuhashi also retaining his place spearheading the Hoops attack despite many predicting that Giorgos Giakoumakis may get the nod.

Really, it was the first test of Postecoglou's Celtic squad depth - ideally, he will not have wanted that as early as game two.

Interestingly enough, there was a school of thought before the 2022-23 season had even kicked off that Celtic had stood still and failed to strengthen their squad enough in the summer.

It was a very strange take on things and also led to the age-old argument of 'what is their strongest XI?'

Postecoglou even had to bat back questions on that very subject matter in the lead-up to this clash.

One thing is for certain: the Aussie doesn't have any favourites in the Celtic team. Just ask the main man - or is it the main culprit? - Jota.

Nobody is guaranteed first-team football for Celtic on Postecoglou's watch... absolutely nobody.

The 56-year-old said: "I know why people will actually think that last week’s team is kind of my first XI and everyone else is after that. I just don’t work that way. It’s not the way I think.

Celtic Way:

"That’s not a judgement on players or someone being better than someone else. I don’t have a first XI."

Despite enjoying over 80 per cent possession the Hoops struggled to break down the stubborn Staggies in a first half that was as stodgy as they come.

Kyogo hammered home the opener on 52 minutes and it seemed that would be that but Alex Iacovitti conjured up a leveller on 58 minutes with Celtic's inability to defend a corner rearing its ugly head again before Jenz and Abada took centre stage.

Champions find a way to win though and, ironically, this Celtic team has yet to click into gear yet.

You get the feeling that the Scottish Premiership champions are merely revving up in the pit lane before entering this title race for real.

As first-team squads go, the rest of the top-flight opposition will not only need to mind Celtic's quality, they'll feel their depth as well.

When you consider last season's joint top league goalscorer Giakoumakis wasn't even in the starting line-up and £4million man Carl Starflets is still to join the first-team fray, it's a sobering thought.

Whatever permutation of Celtic first-team player takes to the field under Postecoglou the end result more often than not tends to be the same: a win for the men in the green and white hoops.

The process, in that regard, has been well and truly trusted. The Ralston and Jenz late goal moments in Dingwall prove that.

All of the Celtic players are comfortable in their own skin and there is an air of confidence and a swagger about the way they are going about their business even when the clock is ticking down.

Every player in the squad seems more than capable of executing the manager's game plan on a game-by-game basis.

You can dress it up whatever way you like but, as Postecoglou said himself: "I don't have a first XI. There is no judgement on players or someone being better than someone else."

Indeed. The Aussie doesn't work or think like that, you know.

As for the question of Celtic standing still? A 34-game unbeaten league run (and counting) is the rather emphatic answer to that.
