News of Ange Postecoglou's appointment as Celtic manager has been met with a mixed reception from Hoops fans.
Some seem happy with it given Postecoglou's impressive managerial resume both here in Australia and in Japan, while others aren't so sure whether the little-known tactician is up to the task of slotting into such huge job.
But while the 55-year-old may not have the biggest reputation in world football, we're certainly well aware of him Down Under.
Before jetting over to Japan to win the J-League with Yokohama F. Marinos, Postecoglou was head coach of the Socceroos and was at the helm during the 2014 World Cup.

Prior to that, he was writing history in the A-League by helping the Brisbane Roar become the first ever team to win back-to-back championships.
On the pitch, his success speaks for itself.
But off it, us Aussies continue to remember him for one moment in particular - a moment Postecoglou says almost derailed his young coaching career.
Back in 2007, when he was youth coach of the Socceroos, Postecoglou found himself involved in one of the most iconic debates in Australian football history.

And, well, it was pretty fiery to say the least.
To give some context, Australia had failed to qualify for the Under 20s World Cup for the first time since 1989 following a demoralising defeat at the hands of South Korea.
And with Postecoglou at the helm, he found himself squarely in the firing line during a live television interview with SBS pundit and ex-Socceroo Craig Foster.

Postecoglou gave his reasons for the team's shock upset, but Foster simply wasn't having a bar of it and essentially called for the coach's head.
The chat started off rather calmly, but that soon changed when Foster told Postecoglou to take some accountability and step down from his duties.
Of course, Postecoglou was left fuming and wasted no time in hitting back.
What followed was one of the most intense yet legendary arguments in Australian television history.
Speaking years after the infamous moment, Postecoglou admitted he actually struggled to get jobs in the months after the tense interview.

"I just didn't feel it was necessary, didn't feel it was productive," he said.
"I knew that interview wasn't going to go well because we just failed to qualify for both the World Cups, our first time in Asia and my reasoning for doing it was trying to explain to people what was coming.
"The accountability already stood with me, but what it did do, it did make me unemployable. I couldn't even get an assistant coaching role.
"It was the reason I went to Greece for a year because I wasn't going to let Australian football stop me from my ambitions as a coach. It was disheartening because I just felt everything I had done with South Melbourne as a manager had been forgotten.

"As all things with life we take our knocks and move on, and it's safe to say it didn't hold me back for too long."
And after Postecoglou's appointment as Celtic boss, that same 14-year-old video has been doing the rounds on social media with Scottish fans fascinated to see that side of him.
