Scolari told Reuters that the Australians had spoken with his agent about him replacing Ange Postecoglou.
"I am one of the names they spoke with ... to see if I was interested in taking them to the World Cup," the Brazilian told Reuters in an exclusive interview on Tuesday.

Scolari told Reuters he would be happy to discuss a role with the Australians, but would want it to be long term, not only for the 2018 tournament in June and July.
