Martin Boyle's devastation is being used as inspiration for his Socceroos teammates at the World Cup.
The dynamic winger has been ruled out of the cup in Qatar because of a knee injury, with Melbourne City livewire Marco Tilio summoned as a replacement.
Australia meet reigning champions France in their cup opener on Tuesday night (Wednesday 0600 AEDT).
And veteran winger Mathew Leckie says Boyle's agony will be sourced for extra motivation.
"We're all sad for him because he did so much and contributed so much to getting us here," Leckie told reporters.
"It's just another reason for us to do it for him.
"He's devastated. But one thing is, he obviously gave everything he could to try to get himself fit.
"He wanted to give it a real crack and it was just not meant to be."
Boyle, a standout performer in Australia's qualification campaign, will remain in Qatar with the Socceroos for the duration of the cup.
The 21-year-old Tilio was shattered to be overlooked for Australia's original 26-man squad.
But with doubt over Boyle, he was flown to Doha as a standby player and Leckie backed his Melbourne City colleague to now grasp his opportunity.
"When he found out that he wasn't selected originally, it was a tough day for him, no doubt," Leckie said.
"It's almost like a second chance and I think his mentality is ... regardless of what is before, he's here now.
"It's funny how football works."
Tilio has impressed with flashes of brilliance in A-League Men's ranks and Leckie believes he had the talent to shine on the world stage.
"I can almost guarantee that he will play some role in this team," he said.
"You know he can do something special.
"He is a great kid, very humble ... if he gets the opportunity, he is the type of guy that will take it."
