DAVIDSON joined Albion from Dutch top-flight club Heracles Almelo for an undisclosed fee on August 5, 2014.
The left-back penned a two-year deal, plus a further year’s option in the club’s favour.
He impressed in all three of Australia’s Group B fixtures against Holland, Spain and Chile at the Brazil 2014 World Cup.
Davidson, born in Melbourne and the son of former Socceroo Alan Davidson, spent three years from the age of 14 in the Japanese youth development system before returning to his homeland to link up with Hume City.
Amid interest from several clubs across numerous different countries, he opted to venture to Europe later in 2009 and joined Portuguese outfit Pacos de Ferreira.
He made his Primeira Liga debut in January 2010 against FC Porto and went on to enjoy a handful of appearances as well as a loan spell at SC Covilha.
Davidson completed a switch to Holland in summer 2011 and joined Eredivisie outfit Heracles.
He made over 50 appearances for the Dutch side, scoring twice last season as he established himself as first-choice left-back.
Having already been on the fringes of senior international recognition, Davidson’s form earned him a maiden call-up against Scotland in August 2012 when he made his debut as a second-half substitute.
Before joining Albion he had made 11 appearances for Australia, including those at the 2014 World Cup.
