“I am sad to leave Melbourne City in these circumstances, but I am so very proud of the players and what the club has achieved during my time here,” said Mombaerts, who previously coached J.League side Yokohama F Marinos.

“We have reached some incredible milestones, we have implemented an exciting way to play, and we have become a true family, playing together every week for our fans, and I have no doubt that Patrick will continue this work. The team is in safe hands under his leadership.

“I have had a fantastic experience in Melbourne and I will always remember my time here with much fondness, but I have been away from my family for a long time and now I must return to care for them in France.”

Kisnorbo takes over having worked as Mombaerts’ assistant throughout the just-completed A-League season and continues an involvement with the club that stretches back to 2013, when he returned to Australia from a lengthy spell in the United Kingdom.

The former centre-half played for Heart of Midlothian in Scotland before spells in England with Leicester City and Leeds United while on the international stage he represented Australia at Under 20, Under 23 and senior level.

“I’m grateful to the City Football Group for their support in my development since I began my coaching journey,” said Kisnorbo.

“Erick has taught me so much and I am extremely grateful for the way he has helped both myself and the club to develop over the last 14 months.

"Melbourne City is in my blood now and I am here to work hard, to give my all and to ensure this team continues to be a team that everyone can be proud to be a part of.”
