Brisbane have so far failed in their first taste of the Asian Champions League (ACL) and Vidosic's first match in charge will be on Tuesday when they play their second last group match against FC Tokyo in Japan.
Six points behind FC Tokyo and Korean club Ulsan Hyundai, the Roar need a minor miracle to make the knockout stages but Vidosic is looking to use the next two games to build for their 2013 ACL campaign.
He backed the vibrant passing game he and Postecoglou formulated over the past two-and-a-half years to also pay off in Asia.
"There won't be any changes. As a matter of fact, we have to develop it even further," Vidosic said.
"We have a very successful style in the A-League. Now we need to find a successful style in the Asian league so that will be our next step forward.
"I've been at the club for seven years, I've been here right from day one and we've been through a lot.
"It's a really exciting time ahead of us."
Details on Vidosic's contract will be finalised in the next week, however Fong stressed it would not be an interim appointment.
The father of Socceroo Dario Vidosic, he denied the club would look to lure his son home while the attacking midfielder was under contract with Adelaide United.
"I don't think there is any other club with such a playing group so there's no need for any (personnel) changes," he said.
"In fact, we have to sit down and progress further and tie (contracted players) up for a few more years so the playing future is looking bright."
Vidosic plans to remain a hands-on coach and was undaunted by the prospect of filling Postecoglou's boots.
"Ange is size 12 and I'm size seven," he said. "So there's enough room to step into his shoes."
