Celtic is fully lodged in Ange Postecoglou's heart now as club and manager strike up an incredible bond.
But there's another side just as close to his heart – Melbourne Aussie rules club Carlton FC.
A proud Australian, Postecoglou led his side into a World Cup and qualified for another as Socceroos manager.
But he remains a massive fan of the dominant version of the sport back in his homeland, though as Australia boss the AFL's dominance often meant he was fighting over scraps of attention.
And in a special Twitter Q&A with Hoops fans one asked him his favourite sport besides football to watch.
And Postecoglou replied: "I follow most sports but growing up in Melbourne you have to love Australian rules football.
"I'm a @CarltonFC supporter so that was the other sport I followed most."
Postecoglou has taken to Scottish football like a duck to water with the Premier Sports Cup in the bag and the Premiership title likely to follow as soon as Wednesday evening.
Asked what his favourite part about our game is, he answered: "I enjoy the passion.
"The passion of the supporters and how they get behind their football clubs here."
And finally, one Celtic supporter demanded his permission to get "Angeball" tattooed on his leg.
"Yeah okay… as long as it's definitely on your leg!"
