Mark Milligan has given the thumbs-up to the Socceroos new formation, despite a 1-1 draw with Iraq in Tehran on Thursday.
The 54-cap veteran anchored a back-three alongside Milos Degenek and Bailey Wright in a 3-2-4-1, a departure from the more traditional back-four employed recently by coach Ange Postecoglou.
"I think it's going to be a very effective formation for us going forward," Milligan told FFA TV.
"It worked well in patches and obviously in other areas it needs some work.
"It's just getting that total understanding of the way we're doing it.
"We'll have a little bit more time to work on it now and fine-tune things before Tuesday night," he said.
