Who will Socceroos boss Graham Arnold pick for their round of 16 clash against Argentina?

Australia are getting ready for their first round of 16 appearance since 2006 in the World Cup as they are set to face the mighty Argentina.

The Socceroos' best performance in the competition is getting to the round of 16 in Germany in 2006.

They will be hoping to do better this time around after beating Tunisia and Denmark in the group stages.

Head coach Graham Arnold will be relying on experienced players such as Mathew Ryan and Aaron Mooy to lead the way, but there are some exciting youngsters coming through as well who could make an impact.

Aziz Behich boasts plenty of experience and gets the nod for Qatar, with Bailey Wright and Milos Degenek also making the cut.

Harry Souttar, Joel King and Nathaniel Atkinson represent younger, but promising options in defence.

Trent Sainsbury, however, was somewhat surprisingly left out.

There's no looking past Aaron Mooy in midfield, with the talented playmaker having proven that he has what it takes to shine at the highest level.

Ajdin Hrustic and Jackson Irvine have also shown what they're capable of in Europe, with a number of less experienced options keen to break into the team, too.

Tom Rogic did not make the cut following his controversial decision not to make himself available for selection for the decisive qualification play-offs.

Mathew Leckie offers experience out wide, while Awer Mabil represents another strong option on the wings.

Jamie Maclaren, meanwhile, will fancy his chances of seeing game time as well, having impressed through the middle previously.

A lot of eyes will be on Garang Kuol, with the promising youngster recently earning a move to Newcastle United after enjoying a bit of a breakthrough season at Central Coast Mariners.
