James Jeggo

After five years in the A-League with Melbourne Victory and Adelaide United, Jeggo joined Austrian outfit Sturm Graz in January 2016.

Jeggo’s career had appeared to stall after the midfielder won A-League Young Footballer of the Year in the 2014/15 season.

But this campaign Jeggo, still only 25, has become a prominent figure at the base of Graz’s midfield – earning his inclusion in the latest Socceroos squad.

Awer Mabil

The pacey winger is an exciting prospect at just 21-years-old, and there are bound to be several big clubs tracking the Australian-South Sudanese player over the next few months.

Mabil’s rise from living in a Kenyan refugee camp has been startling. His senior career started at Adelaide United as a promising teenager, where he made 47 appearances and scored eight goals.

Mabils’s performances earned him a move to Danish Superliga champions FC Midtjylland in 2015, however he made just nine senior appearances in the 15/16 season.

This campaign Mabil has rediscovered his form on loan at Superliga side Esbjerg. 

He has been involved in more goals that any other player for the Danish side, scoring three and supplying six assists.

Riley McGree

Perhaps the most surprise inclusion in Postecoglou’s 30-man squad was Adelaide United teenager Riley McGree.

The 18-year-old only broke into the first team at his club side this season and has since made 12 appearances in the centre of midfield.

Despite Adelaide’s sudden drop-off this campaign, McGree has produced some tenacious performances for The Reds. In round 18 he scored his first A-League goal in a 2-2 draw with Wellington Phoenix.

When asked about McGree, Postecoglou said: “I just think he’s a really exciting talent.

"I watched him from the first couple of games he played and he kind of makes you stand up and notice him straight away for a young guy.”

Danny Vukovic

Goalkeeper Danny Vukovic has been one of Sydney’s star men this season – but it looked like any hope of an international call up had been lost in the mists of time since his hand slap of a ref in the 2008 A-League grand final cost him a six month ban and his place at the Olympics. Since then he’s never even been considered for the Socceroos – despite being one of our most talented keepers. This season the 31-year-old has played every minute of every game for the Sky Blues and kept 12 clean sheets in 22 games. With more than 250 A-League appearances for Central Coast Mariners, Wellington Phoenix, Perth Glory and Melbourne Victory, Ange was big enough to ignore him no longer and give him his long overdue call up.
