In his four years in charge of the national team, Ange Postecoglou has trialled a number of players in that position.

Ivan Franjic, Ryan McGowan, Josh Risdon, Mark Milligan, Milos Degenek, Jason Geria and Tarek Elrich have all featured there.

Now Grant has received a call-up and the fullback is keen to take his chance in the next two World Cup qualifiers.

"There's been a few players to play right back in the last couple of years so if I can get my chance and hopefully do well..." he said.

"You never know, if I can stay in the squad, that's what I'm hoping. It's all up to me at the minute. We'll see how I go."

Grant admitted he didn't expect to be selected for the Socceroos.

"There was a few people in the media talking about it but I didn't really take it too seriously I suppose," he said.

"The media can pump up players and put players down at different times so I didn't read too much into it.

"But when I was selected into the 30-man squad I started to think about it really seriously and then I was lucky enough to make the final cut.

"I'm just really excited to make it. I didn't think it would happen this year, but I'll just run with it. It feels really good.

"Everyone's been really welcoming. Obviously I already know a few of the staff and a few of the boys, but the ones I didn't all came up to me and said hello."

Grant, who has spent his whole career in the A-League with the Sky Blues, said his call-up has opened his eyes to the possibility of playing overseas and in a World Cup.

"It has actually, it's more come from outside people talking to me," the 26-year old said.

"I've always just played the game and tried to enjoy it in the A-League, I love it there. I've never really thought too much about further on.

"Obviously everyone has goals and whatnot, but being selected now opens my eyes up a little bit and I suppose it can enhance my goals in myself.

"Nothing too serious but opens my eyes up a little."

Grant has been watching the Socceroos from the outside and has been impressed by the transformation under Postecoglou.

"They've been doing well," he said.

"Ange's obviously a great coach and since he's come in I think Australian football's gone a long way. Hopefully we can continue that in the next couple of games and make sure we really come home strong. "
