Germany and Chile clash for control of Group B at the Confederations Cup on Thursday with Germany coach Joachim Loew talking up the south American champions.

The 3-2 defeat against the world champions Germany was Australia's fourth FIFA Confederations Cup loss in a row.

SOCCEROOS coach Ange Postecoglou will make a number of changes to the side that faces Cameroon in their must win Confederations Cup match tonight (Friday 1am AEST), but will only decide on the nature of those changes after seeing how the squad pull up after final training in St Petersburg. "It's one of the most flexible teams in the world and this means a special challenge for us".

Pizzi said forward Alexis Sanchez, who had been nursing a left ankle sprain and only played a few minutes from the bench against Cameroon, will likely start against Germany. "It's fair to say that Australia was a team that in a way we could fathom".

Postecoglou said he will make at least two or three changes for the Cameroon fixture with three games in just seven days.

If need be, Low will be able to call on capable replacements in Barcelona's Marc-Andre ter Stegen and Paris Saint-Germain No.1 Kevin Trapp.

"For many, it was the first game in such a tournament, so I am satisfied".

Low's men also got the upper hand in a friendly between the two teams in 2014, winning 1-0 thanks to a goal from Mario Gotze.

Australia and Cameroon played out a 1-1 stalemate at the Confederations Cup on Thursday that further dents both countries' hopes of progressing in the eight-team tournament in Russian Federation.

"Australia play with a lot of fighting spirit and I expect a hard game against a team with a different style to Chile, " he said at a press conference.

"We will have to be at our top level, because if we lose we are done at this tournament".

Broos is expected to stick with the same line-up which leaked late goals by Vidal and Eduardo Vargas against Chile.

Australia kept their Confederations Cup hopes alive with the benefit of another controversial decision by the Video Assistant Referee (VAR) as they drew 1-1 with Cameroon. The striker got his first goal for Germany after he netted against Australia and he believes his teammates have what it takes to get another positive result.

"If we stay true to ourselves and our structure early on, then things will go a lot smoother".
