Jason Davidson –

Davidson’s solid World Cup performances earned him a move to West Brom in 2014, which the fullback couldn’t translate into his first big break. Disappointingly for the then-23 year old, Davidson then couldn’t impress enough at Championship side Huddersfield to earn a permanent move.

The former Ange favourite then lost his Socceroos position to the trio of Aziz Behich, Brad Smith and Alex Gersbach. However, in a bright sign for the future, the 26-year-old recently won the Slovenian league / cup double with his new loan club, Olimpija Ljubljana. 

Ben Halloran –

A regular in the 2.Bundesliga from 2013 to 2015, 21-year-old Halloran appeared in every group-stage match as a substitute, but would only make one Socceroos appearance after the tournament.

A knee injury somewhat derailed his career at Heidenheim and now 25-years-old, Halloran has been unable to break into newly promoted J-League club V-Varen Nagasaki.

James Holland –

Holland failed to make an appearance in 2014 and has only played 14 minutes in green and gold since the tournament.

Now 28-years-old, after success at one of Austria’s leading clubs between 2012 and 2015, Holland is entering a sparse period of his career, unable to carve out a regular place at newly promoted club LASK Linz.

Mitch Langerak –

It’s been a sad story for Langerak, who could, and perhaps should, be pressuring Ryan for the Socceroos number one jersey alongside Brad Jones. Yet a few uncomfortable performances for the Socceroos under Postecoglou all but resigned him to third fiddle – a place he’s now lost to Danny Vukovic.

It’s a hard outcome for the 29-year-old, who performed admirably for Stuttgart after leaving Borussia Dortmund, only to be replaced upon promotion. In another beacon for the future, however, he is now excelling at J-League club Nagoya Grampus.

Ryan McGowan –

McGowan had all the ingredients to become a Socceroos regular – playing each of Australia’s three World Cup fixtures - but a record of moving between dubious leagues let him down.

While he stayed fit and played in a much-needed position for the Socceroos, moving regularly between China, Scotland, the United Arab Emirates and now England’s League One was never going to promote him as a stable option.

Tommy Oar –

A regular Socceroos favourite during the beginning of Postecoglou’s guise, after boasting so much potential a disappointing move to Ipswich Town – where he left after six matches due to homesickness – was the beginning of a lean spell for Oar which hasn’t relented.

Now 26-years-old and struggling for a regular starting position – unable to make their last Champions League qualifying squad – with Cypriot giants APOEL, Oar hasn’t appeared for the Socceroos since 2015.
