In Celtic's statement, one paragraph really stood out. "I have already had great discussions with Peter, Dom and the board about their ideas and strategy for the future of the club," said the new manager. "I know the club's new modern vision aligns very much with mine and we now look to go and deliver on this."

If that means Peter Lawwell will have an on-going say on the "ideas and strategy for the future of the club" then that's news. The club's "new modern vision" is something that needs explaining, too. What exactly does that mean. How modern? How visionary? Nothing will be dull at Celtic Park, that's for sure.

Welcome to Scottish football, Ange. Strap yourself in. Things tend to get bumpy around here.

The new Celtic manager's experience in Australia and Japan is undeniable. The tributes to him are widespread. No-nonsense, smart, successful. To pull off the rebuild of a team and a coaching staff, he's going to have to be everything his many supporters believe him to be.

Doubts were raised over whether Ange Postecoglou had the correct coaching licence to manage in Europe, but Celtic have confirmed there are no issues.

“Ange has successfully achieved UEFA recognition and endorsement in relation to his Pro-Licence issued by Football Australia," the club state.

"He begins working immediately and will be arriving in Glasgow as soon as current protocols allow."

Pre-season starts on 17 June for the Parkhead club, so it looks like the new boss won't be making the start of that as he will have to spend 10 days in quarantine when he arrives in Scotland.

As for incoming Celtic chief executive Dominic McKay, he says that he has been "struck by Ange's passion for Celtic".

"I have been hugely impressed by Ange and his aligned vision to work with me to develop and evolve the club," McKay says.

"He is someone I believe has the coaching and managerial credentials to be a real success at Celtic and we are already working closely together on our plans for the season and seasons ahead.

"He is hugely motivated by this opportunity, honoured to be Celtic manager and eager to be part of the club’s future success."

On the appointment of new Celtic boss Ange Postecoglou, outgoing chief executive Peter Lawwell added: “Ange is a manager we have known about for a number of years and someone who has been prominent in our thoughts for some time.

“He is a great coach who has attractive, winning football in his DNA. He has an excellent record, he is a very strong personality and someone with a real desire and passion to take Celtic forward.

“I wish Ange and Dominic [McKay] all the very best for the future and I am sure they will work towards delivering great success to the club and our supporters.”

Ange Postecoglou has earned praise from Pep Guardiola, is one of the "top 10 coaches anywhere in the world" and will prove "no second choice".

Those are the words of Tokyo-based football author Scott McIntyre, who adds that the 55-year-old Australian is a "serial winner and tactical innovator".

"Celtic supporters should be absolutely thrilled to grab a guy of his pedigree," said McIntyre on BBC Radio Scotland when asked about the man the club appointed after the long pursuit of Eddie Howe collapsed.

But the former Yokohama F Marinos boss represents "a huge risk", according to Pat Bonner.

And Natasha Miekle, from the Celtic State Of Mind podcast, added: "Every result that goes wrong, every point that is dropped, will be scrutinised through the lens of 'what could Eddie Howe have done?'"

So what can Celtic expect from Postecoglou? My colleague Martin Watt found out, and you can CLICK HERE to have a gander.

David Scott: "Celtic showing they have complete confidence in appointing Postecoglou by offering a 12-month contract. Lose the Champions League qualifier and he may be out of the job in less than a month."

People might look at that as being harsh, David. But I must admit, the contract length raises a question...

As a neutral, this is exactly where I am at with this. We often find ourselves asking for something different in Scottish football, now we've got it.

It's going to be really intriguing to see how it all plays out as there is no doubt that Ange Postecoglou has a HUGE job on his hands.

But at the same time, you don't have to look far to see his credentials. It's set up for some season...

Postecoglou also says that work is already underway to make additions to the squad.

“I have already had great discussions with Peter [Lawwell], Dom [McKay] and the board about their ideas and strategy for the future of the club," he says.

"I know the club’s new modern vision aligns very much with mine and we now look to go and deliver on this. In everything we do we aim to give our fans a successful team of real quality, which they are excited about and can be proud of.

“We have already begun work on our plans for adding to the squad - we aim to bring players of quality to Celtic to enhance the existing core of great talent."

Postecoglou won back-to-back A-League titles with Brisbane Roar and spent a season with Melbourne Victory before becoming manager of Australia in 2013.

He led the national team at the following year's World Cup and qualified for Russia 2018 but left in late 2017, moving to Japan, where he won the J-League with Yokohama in 2019.

His main task will be to the regain the Scottish Premiership title after city rivals Rangers halted Celtic's quest for the historic 10 in a row.

The Australian arrives in the midst of a major rebuild, with chief executive Peter Lawwell being replaced by Dominic McKay, Nick Hammond stepping down as head of football operations and long-serving captain Scott Brown leaving to join Aberdeen.

Postecoglou will need to quarantine on arrival from Japan, while his opening game in charge will be a Champions League second qualifying round tie in July.

Celtic's new man in the dugout also told the club's website that he will be doing everything he can to get the side "back on top" while delivering "the kind of football our fans appreciate".

"We want to entertain our fans and we want to win," Postecoglou says. "These are the objectives which I always set myself.

“When you think of Celtic, you think of supporters and my dream is to see our fans back at Celtic Park with us as soon as possible.

"We all hope things are changing for the better and can see our fans soon as they are vital to everything I want to do. We need our supporters back by our side."

It's an interesting point from Matt, does any sense of being underwhelmed come from the fact Postecoglou is fairly unknown in these parts?

You'll struggle to find any negative feedback from those based in Australia or Japan...

Keep the tweets coming in @BBCSportScot.

@TheRealMattLock: "As a Brit down under, I can tell you Ange is effective and well respected down here. But if you are looking for excitement, he's not your guy. Might be just what Celtic need though?"

New Celtic boss Ange Postecoglou says he "has been given one of the greatest honours in football".

"The responsibility to lead our magnificent football club into the future is one that I will cherish dearly," he adds.

The former Austrialia boss goes on to say that Celtic are a "proper footballing institution".

"I know Celtic is a true way of life for so many people and I know the demands which come with this position – I am ready to do all I can to meet those demands."
