Socceroos coach Pim Verbeek has opted for two established partnerships, selecting the Melbourne Victory pair and Central Coast's Dylan McAllister and Matt Simon as the four forwards in his 21-man squad.

With little time to experiment, Verbeek wants his strikers on the same wavelength and ready to go.

But the coach also has a track record, especially in away fixtures, of opting for a lone target man up front with attacking back-up from midfield.

Allsopp's preference, naturally enough, would be to start alongside Thompson, but if playing one-out gives him the opportunity to win his third cap for his country and first as a member of the starting 11, he'll take it.

"I would play anyway he wanted me to play," said Allsopp of Verbeek after training in scorching heat at Gosch's Paddock.

"Definitely I could do it - I have to do a bit of everything for Melbourne Victory, so if there's certain jobs that he wants me to focus on then I would do them as best I can."

The 30-year-old, who's been among the A-League's leading goalscorers for the past three seasons, was pleased and surprised by his call-up.

"There's a few times when I thought I should have probably been in (the national squad) but you just go with it and take it the way it is," Allsopp said.

"Sometimes you look at it and think you've just got to push those players out and just keep doing your best.

"It's not about really making points, you just want to go out and have a shot at it, and if I can start I'll give it my best shot and hopefully do the job."

Meanwhile, Thompson, the second-most experienced member with 30 senior appearances behind captain Craig Moore (40 caps), warned the squad - selected exclusively from the A-League because of the unavailability of foreign-based players due to the scheduling of the fixture on a date not sanctioned by FIFA - is on a hiding to nothing.

"If we go to Indonesia and don't get the result that we want, obviously people are going to start saying 'why are we using A-League players, why aren't we using overseas players?'," said Thompson.

"So there's going to be a lot of pressure on us and it's not going to be easy going there, the temperature ... and we haven't played together before as a Socceroo unit.

"It's not going to be easy for us because we don't know each other, we only play against each other and we don't actually play with each other.

"There's going to be pressure and I hope that the A-League players can do really well."

Thompson said he was looking forward to meeting his namesake from Newcastle, Matt Thompson, whose hat-trick powered the Jets to a 4-2 win over Victory in their most recent meeting just before Christmas.

"I don't know Matty Thompson from a bar of soap how he plays ... I hate him," laughed Thompson.
