Pics: Socceroos training

The Socceroos are ramping up their preparation for January's Asian Cup with a series of high-profile friendlies.

First up is European heavyweights Belgium who take on the green and gold this Friday morning (AEST) in Liege.

After winning plaudits for their attacking football in the World Cup, Ange Postecoglou's men are keen to get some wins on the board.

Postecoglou has called up a youthful 20-player squad with a sprinkling of veterans to take on the Red Devils.
