Celtic lost their first Premiership match in 364 days against St Mirren last Sunday.

There has been no shortage of people lining up to dish out advice to Ange Postecoglou since the loss in Paisley.

Meanwhile, the manager has seized the opportunity for a rare chance to go back to his homeland. He's part of a high-powered Celtic delegation who has flown to Australia.

They are all there for talks and promotional activities relating to Celtic's involvement in the Sydney Super Cup.

Celtic will take on Sydney FC on Nov 17, then Frank Lampard's English Premier League side Everton three days later.

Tony Haggerty assesses the five areas the boss will be mulling over while back in his homeland.

Guarding against complacency

The 57-year-old will never allow his men to be complacent. He is far too professional and meticulous to allow that to happen. However, if he's reading the latest stats reports, the Aussie could be forgiven for thinking that the Scottish Premiership title race is already a done deal. It's not of course. All the data is suggesting a Celtic landslide title win some by 20 points or more. Latest forecasts say that Celtic will run out comfortable winners of the Scottish Premiership due to Rangers' wonky, shot-shy form. Whilst one defeat doesn't a disaster or crisis make, Postecoglou even joked that he left the country and returned to Australia because Celtic lost for the first time in a year. He is used to blocking out all the noise and being able to get his players to do the same. It's just as well really as titles are earned and won by sheer hard graft and endeavour on the pitch and not determined by a computer algorithm. Postecoglou has everybody in Glasgow's East End singing from the same hymn sheet, not a spreadsheet.

Coming back stronger in every competition 

We Never Stop. It became a Celtic mantra for the ages last season. Whilst it was temporarily halted in Paisley you get the feeling that Postecoglou is already plotting how to deliver another massive unbeaten run. He hates losing, although he admitted that he'd become bored of winning all the time. The Aussie loves the challenge, and there is no bigger challenge in football than making Celtic a force in European football again. That flicks the Hoops manager's switch. In the aftermath of the St Mirren defeat, Postecoglou said: "Celtic haven’t been in the Champions League for five years, I don’t want to just do these six games as an experience. I want to take some scalps and then create a good platform, qualify again, and bridge that gap a little bit more. The Real Madrid game was a great night, people told me how special European nights are at Celtic Park, the Champions League anthem gets played and the noise was incredible. It was special, but it gives me the motivation to bring success. That’s where the club needs to be. High standards we have to match and succeed." These aren't the words of a man who is going to rest on his laurels anytime soon.

Constantly being linked with bigger jobs:

It doesn't matter how many times he says it. People aren't listening. Postecoglou is "Living the dream" at Celtic. First, it was Brighton and Hove Albion. This week it was Leicester City. Next week who knows? It looks like Postecoglou is going to have to put up with endless speculation linking him with jobs down south. He is perfectly happy at Celtic but increased success does put him on the football radar of wealthier clubs. Whilst promoting the Sydney Super Cup on his rounds in Australia, Sky Sports host Waleed Aly suggested that he might not be here in November as he could be off to Leicester before the homecoming tournament takes place. Postecoglou gave him short shrift: "Don't read too much into it, Waleed, 12 months ago, I was the favourite to get the sack by Christmas, mate, so things change pretty quickly in football." Like an Aussie cricketer, he keeps having to bat away idle speculation on his future. It's grinding the Aussie's gears a bit. He is in a job at this moment in time. A massive one at that. There will come a time when he moves on but this project still excites him. Postecoglou, for the time being, is in the construction not deconstruction business, and that may be bad news to some who want to see him gone from the Scottish game... or maybe it's just wishful thinking on their part.

A robust set of financial figures means there is still money to spend

Much has been made of Celtic's squad depth and the fact that the manager is striving for two players for every position in the team. He made some six changes to the line-up against St Mirren and conceded himself that it might have been too many for a game of that magnitude. Having made nine changes in a cup tie against Ross County in Dingwall, which they won 4-1, he would have been perfectly entitled to trust his charges no matter what starting XI he sent out in Paisley. The defeat will have given him some time for sober reflection and food for thought. The fact that the financial figures released showed that Celtic have some £30 million in the bank, discounting the money coming in from reaching the Champions League group stages this season means that Postecoglou can start looking ahead to bringing in some fresh blood in January's transfer window. The Aussie has barely put a foot wrong in the transfer market so far, and aided and abetted by CEO Michael Nicholson, the two men seem to be working in tandem both on the football and business side of the operation. Celtic are in rude health financially, and every squad can always be improved upon. Postecoglou is well aware of that, and his work ethic is such that it wouldn't be surprising to learn if he was already running the rule over potential January signings.

Turnbull, Starfelt and Carter-Vickers are all out injured

It would be a stretch to say that Celtic are suffering from another injury-jinx or crisis. However, the club once again have been hit by a spate of injuries during the international break. Swedish and USA central defensive pairing Carl Starfelt and Cameron Carter-Vickers were both forced to withdraw from their respective squads, whilst David Turnbull joined them on the cracked list after leaving the Scotland team to get treatment on an ankle injury. The high-octane intensity of Celtic's first team training and matches make injuries more commonplace among the Hoops squad, but that won't make Postecoglou alter his regime. It is a situation that the club will monitor moving forward. On the resumption of football after the international break, Celtic will play 13 fixtures both domestically and in Europe within the space of 42 days. It is a hectic schedule, and the squad depth will be tested to the full in a period that will help determine their Premiership, League Cup and Champions League fate - injuries permitting of course.
