Egypt captain Salah is a doubt for the round of 32 clash against the Socceroos after suffering a hamstring strain during the 1-1 draw against Iran.

Centre back Herrington, however, hopes the former Liverpool stalwart will be fit to line up on Saturday.

"It's nice to verse (compete against) players like that. Really, that's where you want to be, that's who you want to verse," Herrington said.

"So to be given that opportunity, hopefully, it'll be special, and I can't wait."

Herrington became the youngest Socceroos player to start a match at the global tournament in a high-stakes group clash against Paraguay.

In only his fifth international, he barely put a foot wrong in the 0-0 draw against the South American side, which ensured Australia would meet Egypt as the second-placed team in Group D rather than take on Germany as the third-ranked.

"That was the best moment of my life," said the Colorado Rapids rising star. "I knew how important that game was, not just for us but for the whole country.

"So I was looking forward to it. Obviously I'd dreamed of that moment since I was a kid and I just really wanted to embrace it, enjoy it."

There may be more golden moments for Herrington in the near future.

Tony Popovic's side will bid to become the first Australia team to win a World Cup knockout match.

Herrington has also been linked with a move to Barcelona, a development that surprises none of his teammates.

Midfielder Connor Metcalfe said some players might be nervous about a teenager's decision-making when under pressure in defence.

"Nothing really fazes him, he never looks nervous. I'm not nervous when he has the ball," Metcalfe said.
