Smith is all green and gold

Young Australian left-back Brad Smith says he is "over the moon" with his Socceroos call-up, despite having represented England at youth level.

The Liverpool left-back, who is on loan at English third-tier club Swindon Town for the 2014-15 season, has previously played for England's Under 17, U19 and U21 teams.

But having been picked by Ange Postecoglou last week, Smith is keen to represent Australia at senior level with the 20-year-old Penrith-born defender set to be locked down by the Socceroos if he gets game time in next month's friendlies versus Belgium and Saudi Arabia.

Speaking to the Swindon Advertiser on Tuesday, Smith revealed his joy at being one of the 20 names in Postecoglou's latest squad.

"I didn't really expect it and got the call-up and I'm over the moon really. My family and all my friends are very proud," he said.

"Obviously, I thank everyone with England and all the staff through the youth levels at England.

"I just decided to play for my homegrown country where I was born as a full international.

"I was born there (Australia) and I moved over here when I was 14 for family reasons. I started playing football over here and went from there really."

Smith has only made one competitive appearance for Liverpool and has been sent to Swindon to gain more experience of senior football.

Able to play anywhere on the left-hand side, Smith has impressed Postecoglou with his pace, while the Australian youngster has already made three appearances for Swindon in League One and another in the Capital One Cup - generally as a wing-back.

Smith is expected to play in Swindon's next cup tie against Brighton and Hove Albion on Wednesday morning (AEST) as well.

The British press is also reporting Robins' manager Mark Cooper will pick Smith's fellow Australia international Massimo Luongo against Brighton after the 21-year-old midfielder missed Swindon's league win on Sunday with a hamstring problem.
