Socceroos coach Ange Postecoglou has predicted a big future for the trio of players cut from Australia's travelling squad to Brazil.
Curtis Good, Adam Sarota and Josh Brillante missed out on the 27-man preliminary squad after taking part in a two-week World Cup training camp on the Central Coast.
The Brazil-bound Socceroos will fly out from Sydney International Airport on Wednesday.
Postecoglou broke the news to the players after Monday night's 1-1 farewell friendly with Bafana Bafana waiting to see if there were any uforseen injuries.
But he said it was a tough decision and "obviously disappointing for those boys" who had worked hard to make it on the flight to Rio.
“A couple of decisions (were made) mainly because just their bodies not being able to hold up," he said.
"I’m super confident that all three will play a big part in the (Socceroos) future.”
Good, 21 has yet to recover from a hip flexor problem picked up in the friendly against Ecuador in March while Sarota, 25, is coming back from a long-term injury. Brillante, 21, was a casualty of the intense competition for places in midfield.
The Socceroos mentor was effusive in his praise for all three.
“With Curtis we wanted to give him every chance,” Postecoglou said.
“To his credit he worked really hard and did everything the medical people wanted him to.
“But we sort of had a time line in our heads and we tested him out a few days ago and he just couldn’t get back up to where he wanted to.
“So the wise decision for him was to send him back home and get him to sort out his injury once and for all.”
Postecoglou said Good was given until the 11th hour to prove his fitness.
“That’s just how highly I rate him,” he said of the Newcastle United player.
“The next World Cup’s four years away. I think Curtis as he showed against Ecuador, if fit, he could have played a significant role in this World Cup so I wanted to give him every chance."
He also indicated there was a need to look at how Good’s injury was managed.
“One thing we do know is that is probably still hasn’t been correctly treated,” Postecoglou added.
“Even when he was back in the UK his build-up in training was good but it was only when he tried to get really top speed at the highest intensity that his body broke down.
“So he had three or four failed attempts which suggests to me it’s probably something he needs to deal with, and his club needs to deal with, a little more urgently now to really find out what the problem is.”
As for FC Utrecht midfielder, Sarota, Postecoglou said there was a concern how his fitness would hold up in the pressure of a World Cup.
“Adam’s just come off a knee reconstruction – this is his first year,” he said.
“Again he’s worked hard to get back into first team regular football. We weren’t confident with the intensity we’re training and the tempo he’d be able to carry through.
“I think, even for himself, it is best that he gets a good preseason under his belt. He knows that he can play at that level again and come back stronger.”
And there was plenty of encouragement for Newcastle Jets young gun Brillante.
“With Josh it was always going to be balancing the squad,” Postecoglou said. “We’ve got quite a few midfielders in the squad.
“I wanted to bring him in because I rate him very, very highly and I know he’ll become a player who will be called up again if he continues to improve.
“But with so many players in his position, the balance of the squad was such that one of the midfielders had to miss out and that was him.
“We had to wait until last night just in case there were any injuries or anything unforseen that happened in last night’s game.”
The travelling squad of 27 will be trimmed to 23 ahead of the World Cup start in just over two weeks.
