Celtic head to Hibernian tonight for their final away match of the Scottish Premiership campaign.
And ahead of the showdown at Easter Road, the early squad news is in.
Hibs manager Lee Johnson will select from the squad he had at his disposal for Sunday’s defeat by Rangers. Mykola Kukharevych is still missing along with long-term absentees Martin Boyle (knee), Kyle Magennis (pelvis) and Aiden McGeady (hamstring).
Aaron Mooy is still struggling for Celtic and Alistair Johnston has returned to training following a leg knock but will not feature. Cameron Carter-Vickers is out for the season after knee surgery.
Ahead of tonight's clash, Celtic have only taken a point in two games since clinching the title and face a Hibs side who are still battling for a European place.
Postecoglou said: “We just go out there and try to play our football but we know the league is done.
“We can’t lose the league now, unless someone has brought in a new rule. The players are aware of that so I can’t go about pretending, trying to create some alternative universe where they are trying to achieve something they have already achieved.
“But we still want to enjoy our games and prepare for the cup final and the best way to do that is play our football and take each challenge as it comes.
“The players are training well and we want to finish the season strongly.”
Meanwhile, Postecoglou was completely unmoved by news from Rangers that several experienced players will be leaving Ibrox this summer including Allan McGregor and Scott Arfield.
When asked if he expected a tougher title challenge from their rivals next season, he said: “I don’t know why that would even concern me to be honest.
“This time last year Rangers were in a Europa League final and a Scottish Cup final, and they strengthened after the season didn’t they?
“So does anybody really care? Like, seriously. We didn’t start favourites in my first year and probably weren’t overwhelming favourites this year, so people will say what they want, mate. Everyone has got a plan until they are punched on the nose and then you kind of reassess from there.
“When we start next year, when the games start, everyone will see who is really strong and who isn’t strong and all that sort of stuff.
“Right now, league-wise anyway, it’s the equivalent of junk-time, mate, so we just get on with it.”
