Three games in the space of 14 days will determine if the Socceroos book their berth on the world's grandest stage for a third straight time, starting with Tuesday's encounter with heavyweight Japan at Saitama.

Rogic looms as a potential X-factor in the midfield, with the 20-year-old's pace, fearless style of taking on defenders and vision an advantage in breaking down an imposing Japanese outfit.

His transfer to Scottish giant Celtic in January for $750,000 on a 4½-year deal was at the perfect time in his young career.

Lifting the league championship and the Scottish Cup has given him plenty of confidence of making his mark at the international level, after receiving his first cap for the Socceroos in a friendly with South Korea last November.

''I think I'm a better player and much well-rounded and I've had a bit more experience since then,'' Rogic said. ''I feel I'm a lot sharper and stronger as well.

''I feel like I've developed in the past six months, continue to progress and am heading in the right direction.''

Rogic's rise has been stunning, emerging from the obscurity of Canberra club soccer after winning a worldwide talent search.

That stint at the Nike Academy in England led to securing a contract with the Central Coast Mariners in the A-League.

Rogic was an instant sensation and played a pivotal role in the Mariners winning the league championship in the 2011-12 season.

And while he headed overseas before they went on to claim the grand final last season, the Mariners arranged for Rogic to receive a winner's medal given his contribution in the first part of the campaign.

''Ha ha, it's not bad, I don't think there's many players that start their careers like that,'' Rogic said.

''It's a good feeling and it does give you a lot of confidence.''

''Firstly with the Mariners, and then to win the league and cup double at Celtic has been another good experience.''

Rogic will have a short two-week break after his Socceroos commitments before returning for a pre-season training camp in Germany with Celtic.

By then, Australia will know if the Socceroos have clinched a place at next year's World Cup in Brazil.

The Socceroos are tied for third on six points with Oman, but have a game in hand and are only a point behind second-placed Jordan.

After the game in Japan, the Socceroos host Jordan in Melbourne (June 11) and round out their campaign against Iraq in Sydney (June 18).

''That's the ultimate goal, to go to the World Cup,'' Rogic said.

''The next few weeks are going to be quite tough.''
