One of the first names on the team sheet, Leckie's incredible pace and engine - allied to a strong season at club level - have him shaping nicely to be a vital ingredient in the Caltex Socceroos' upcoming campaign.
He has carved out a respected reputation in Germany following his move from Adelaide United to Borussia Monchengladbach in 2011.
The Victorian later turned out for FSV Frankfurt and, after suffering relegation with Ingolstadt, secured a stay in the Bundesliga by joining Hertha BSC, where he has scored five league goals in his debut season.

He was equally effective at the AFC Asian Cup the following year and could yet have his best moments in a green and gold shirt to come in Russia.
