Football commentator Mark Bosnich believes the Socceroos should unleash Daniel Arzani and Tim Cahill during their second World Cup match against Denmark in Samara on Wednesday.
The green and gold need a result to keep their hopes of progressing to the knockout stages alive after a 2-1 loss to France in their opening group C game.
Bosnich is adamant Cahill will play a part against the Danes, just not from the start because of his lack of time over the past six months.
"I’d say to him (Cahill), ‘I’m not going to start with you but you are going play a major part tonight," Bosnich told SEN.
"In my opinion, if you start him, he’s in great condition for his age but he’s only played 65 minutes in the last 10 games or so in the Championship (with Millwall).
"To play a full game, he’s not in that condition.
"Whether you start him and play him (for) the first bit or you bring him on with half an hour to go, I think he needs to play some type of part.
" I think basically he will play some part in this game."
Arzani received only his third international cap against Les Bleus with the 19-year-old scoring his first international goal in the pre-World Cup friendly against Hungary.
With the Socceroos in need of a positive result, Bosnich believes Arzani is the man to offer something different in attack.
"I would start with Daniel Arzani,” he said.
"The other day, Robbie Kruse put in a good shift defensively but from an attacking point of view offered us nothing.
"Daniel Arzani is a player who offers something completely different that we haven’t got.
"He’s a player that we aspire to produce all the time and somebody that we are going to enjoy watching for a very long time."
France and Denmark lead group C with one win from their first game, while the Socceroos and Peru are yet to get a point.
Australia need to win at least of their remaining two games against the Danes and Peruvian to have any chance of playing in the round-of-16.
