Rado Vidosic will lead Melbourne City for the next two-and-a-half seasons after being announced as the permanent replacement for Patrick Kisnorbo.
The Croatian had been managing the A-League Men side on an interim basis since Kisnorbo left to join French outfit Troyes in November.
Vidosic was already at the club as their A-League Women coach but will now take charge of the men's side until the end of the 2024/25 campaign.
"We are a club that looks internally before we look externally and when we know we have the right person within our ranks, we have no hesitation in giving them the first opportunity," City's football director Michael Petrillo said.
"We've seen over the years his ability to implement the City way of playing football starting with our academy, then our A-League Women's team and over the last couple of months, the A-League Men's team.
"Along with his belief in the way we play, he has also continued to nurture the culture inherent within the football club and this is one of the most important factors we took into consideration before making this appointment."
The 61-year-old has suffered just one defeat in the eight games since he took charge, with City seven points clear at the top of the table.
His son Dario remains in charge of Melbourne City's A-League Women team.
