Ange Postecoglou's footballing expertise will be called upon once again as he offers advice to fellow countryman Patrick Kisnorbo - with the former Scottish Premiership defender taking up a managerial role in Ligue 1.
Having moved from Australian side Melbourne City to ES Troyes in the French top-flight, Kisnorbo is ready to take on some of the world's biggest stars such as Lionel Messi, Neymar, Kylian Mbappe and more across the Channel. The former Hearts, Leicester City and Leeds United star is now part of the City Football Group (CFG), which owns Manchester City, New York City FC, Troyes, Melbourne City, Palermo and Yokohama F. Marinos - Postecoglou's former club - to name but a few, making even more links between Celtic and CFG as a result of staff joining the Hoops such as Jeremie Frimpong, Patrick Roberts and Ange himself.
And, with former Rangers star Kevin Muscat taking charge of Yokohama F. Marinos, there is an Australian revolution underway at CFG - something the Celtic boss could be more than happy to help out on, with Kisnorbo admitting coaches from his home nation 'hold value'.
