Central Coast Mariners coach Graham Arnold is poised to leave the A-League champions for a job with an Asian club.
Arnold is to travel to Asia this week to talk terms with what the Mariners described as a "successful top-flight side".
A decision on the prospective deal is expected by Sunday at the latest.
The Mariners said they had long been preparing for life after Arnold, who recently missed out on the Socceroos job to Ange Postecoglou and has made no secret of his ambition to coach at the highest possible level following several successful A-League seasons.
"With strong interest from a club in one of Asia's biggest leagues, the Mariners acknowledge that there is a strong probability he has coached his final fixture for the 2013 Hyundai A-League Champions," the club said in a statement.
Should Arnold sign in Asia, his current assistant Phil Moss will be promoted to head coach.
"The success of our club over the past three seasons under Graham Arnold and his staff always meant Graham would receive interest from rival Hyundai A-League and foreign clubs," said Mariners Group general manager Peter Turnbull.
"As such, we have been planning for the past 18 months for Phil (Moss) to take on the role of head coach upon Graham's departure.
"Of course, Graham has been helping prepare Phil for the position."
"We will know for certain by no later than Sunday whether or not Graham has finalised a deal in Asia, and will notify our members, fans, and media of any updates as soon as possible."
