Oar saw off the likes of Mathew Leckie, Ben Kantarovski and Leigh Broxham to claim the NAB  Young Footballer of the Year award this week.

"He's had a fantastic year and been a fantastic performer for us," Postecoglou said. "In a difficult season for the club, the youngsters have stood up and Tommy was at the forefront of that with Socceroos selection. He fully deserves his win."

Postecoglou expected Oar's win to push Oar and other Roar youngsters on to bigger and better things.

"(The award) indicates if you give young players an opportunity, they can take their game to the next level," Postecoglou said.  "And I think it will encourage (Oar) to work even harder." 

Oar himself is still taking in his success.

"I don't know really what to say, I'm just really happy," the 18 year-old said. "(But) I'm pretty stoked at the moment."  

However a humble Oar refused to be swept away by the accolades and awards, happy just to see his hard work on the field beginning to pay dividends.

 "I think things are happening pretty quickly," Oar said. "But it's always good to get recognition for things like this.I wasn't expecting it by any means but it is good to win (the award)."
