Mark Schwarzer will be the Socceroos custodian, barring injury, but the battle is on to fill the two other slots as his back up.

Verbeek is in Japan at present and took in Adelaide United's Asian Champions League clash against Sanfrecce Hiroshima.

The outgoing Australia boss was there to take another look at Eugene Galekovic and Verbeek has confirmed that the former Melbourne Victory reserve is firmly in the frame.

"We have Schwarzer, (Reading's) Adam Federici and (Middlesbrough's) Brad Jones," he told the Adelaide Advertiser.

"Eugene is playing very well so he's an option and we still have (Elfsborg's) Ante Covic and (Sivasspor's) Michael Petkovic on the list, but he's not playing at the moment.

"Eugene is very good. At least we have five possibilities for three positions."

Clint Bolton and Danny Vukovic are the other A-League keepers hoping they might yet get the call from Verbeek.
