Halloran, who was part of Australiaโ€™s 2014 World Cup squad, is keen for more game-time in the lead-up to the 2018 event in Russia with a view to making the Socceroos squad.

The speedy 25-year-old midfielder has only managed 10 appearances and one goal for German 2.Bundesliga outfit Heidenheim during the 2017-18 campaign, the last being in mid-October.

Heidenheim has confirmed Halloran missed the resumption of training this week and wonโ€™t be part of their upcoming training camp in Spain, with a view to completing the formalities of the move to Japan.

Halloran may have played all three of Australiaโ€™s 2014 World Cup games under Ange Postecoglou but the ex-Socceroos boss hadnโ€™t utilised him since September of that year.

With a new Socceroos coach to be confirmed in the coming weeks, Halloran is looking to make a move to bolster his 2018 World Cup chances despite not being in the national team frame for three years.

Halloranโ€™s to-be new club finished as runners-up in Japanโ€™s second tier in 2017, second only to Tando Velaphiโ€™s Shonan Bellmare.

The Nagazaki-based club have never competed in Japanโ€™s top flight, having been founded in 2005.

Meanwhile, another ex-Germany based Socceroo Mitch Langerakโ€™s plight for a new club became more obvious overnight after being an unused substitute in Levanteโ€™s Copa del Rey 2-1 win over Espanyol.

Langerakโ€™s only appearance since moving from Stuttgart to Levante in August came in the cup, but number one Raul Fernandez was preferred for their last 16 first leg overnight.

The 29-year-old played every minute of Stuttgartโ€™s promotion campaign last term but was usurped as number one by new signing Ron-Robert Zieler prior to this season, prompting his move to Spain.

Langerak faces a battle to retain his Socceroos spot, with three goalkeepers to go to Russia, with Mat Ryan, Adam Federici, Danny Vukovic, Mark Birighitti, Brad Jones and Eugene Galekovic among the options.
