A 2-1 win over hosts Thailand on Saturday lifted Graham Arnold's side to the top of their group, and means they now need at least a draw against Bahrain on Wednesday morning (AEDT) to guarantee an AFC U-23 Championship quarter-final.

The tournament's top three will progress to Japan later this year, and Western Sydney Wanderers talent Mourdoukoutas said their comeback win over Thailand showed they were capable of achieving just that.

"To come back from 1-0 down, it's not easy in tournament football. But the way we reacted as a team - excellent," Mourdoukoutas said.

"It shows we're a strong bunch and no matter what we get thrown we'll deal with it and push on."

A draw against Iraq in their tournament opener leaves the Australians needing just one point to progress to the knockout stages.

But the Olyroos won't be content to simply knock it around and settle for a draw.

"Respect for Bahrain, but if we do all the things right it should be a good result for us and we're looking to kick forward into the quarters," Mourdoukoutas said.

A berth in the final or win in the third-placed play-off will ensure they avoid a third-straight failed Olympic qualification campaign and open up a route 20-year-old Mourdoukoutas admitted was not on the radar as a junior.

"I was just thinking about this last night before I should've gone to bed," he said.

"I didn't imagine myself, when I was younger, that football could be a pathway to move into the Olympics.

"The fact that there's a very real opportunity now and we're really close to achieving that goal - just a few wins and quality performances - it would mean the world to me.

"As a young aspiring player and any athlete in the Olympics ... it's one of the most amazing experiences you could have, so we're taking it as it comes but looking forward to what's ahead."
