The Melbourne Victory coach is disappointed at the news his captain's knee problem has worsened after linking up with the national team against the club's wishes
Mark Milligan has been sent home from the Socceroos camp due to injury ahead of Friday's daunting friendly against France, with Ange Postecoglou claiming he didn't want the midfielder to travel.
Milligan has also been ruled out of the Socceroos' friendly against Canada and is on the way back to Australia after his ongoing knee problem flared.
The 28-year-old arrived in Paris hoping to be fit to take part in the match at the Parc des Princes but is now in doubt for Melbourne Victory's second-round A-League clash away to Adelaide United.
No additional players will be called up to the Socceroos squad, which has also lost attacking midfielders Tom Rogic and Brett Holman.
Victory coach Postecoglou said on Friday the club tried to convince the Socceroos camp that Milligan should never have made the journey to France.
"Our medical department wrote to FFA and explained the situation and our strong recommendation was he wouldn't travel. We didn't think he'd be right," Postecoglou said.
"To be honest I don't think the trip did him any good. Our preference was he stayed here, but they wanted him over there to check him out.
"It's been a bit of a fruitless trip for him. We'll see what kind of condition he's in when he gets back, but reports are it's kind of gone backwards rather than progressed.
"I didn't say 'please'. Maybe I should have said 'please [don't take him]'."
On the back of last month's 6-0 thrashing against Brazil, Australia are aiming for a much-improved showing against 25th-ranked France, who are still to qualify for the World Cup.
There is speculation another heavy loss could cost head coach Holger Osieck his job.
Tommy Oar [back] and Dario Vidosic [groin] trained away from the main group and are also under fitness clouds.
Defender Sasa Ognenovski sat out the session completely, meaning Rhys Williams could partner Lucas Neill in central defence.
The Socceroos have at least received a boost with news France are set to be without a host of star players, including injured Arsenal centre back Laurent Koscielny, as Didier Deschamps prepares to field an experimental line-up.
