Teen sensation Lucas Herrington and son-of-a-gun Paul Okon-Engstler are barely scraping the surface of their talent and could be anything.
That's the view of Socceroos boss Tony Popovic after selecting the "fearless" pair in his World Cup squad.
Colorado Rapids defender and ex-Brisbane Roar sensation Herrington, just 18, has thrived since joining the Socceroos, including playing 90 minutes in the 1-0 loss to Mexico at the Rose Bowl on Saturday night (Sunday AEST).
"He can be really good. He's just started out and he's doing so well in (Major League Soccer). He's played every minute of every game," Popovic said.
"He keeps backing up. I don't want to jinx him now - or us - but he's very robust to keep backing up every (game) and they're (Colorado) in every cup competition; it's every three or four days.
