The A-League's biggest ever signing, Juventus legend Alessandro Del Piero pulled the strings at Sydney FC for two eventful seasons. He was the club's leading goalscorer in both seasons, highlighted by a memorable four-goal haul against Wellington in January 2013.
David Villa - Melbourne City (2014 - Present)
The signing of Villa, who rivals Alessandro Del Piero as the biggest name to ever to play in Australia, has helped launch the rebranded Melbourne City club . Spain's all-time leading goalscorer signed on for a 10-game guest stint ahead of his move to New York City FC. He has won the World Cup, lifted the La Liga title in Spain for Barcelona and Atletico Madrid, a UEFA Champions League title and represented Spain at three World Cups.
Damien Duff - Melbourne City (2014 - Present)
Republic of Ireland winger Damien Duff joined Melbourne City this year on a one-year deal. Duff has a century of caps for Ireland and more than a decade’s experience in the English Premier League, including two winner’s medals from his time with Chelsea.
The A-League's first major signing, Dwight Yorke, was in Sydney FC's inaugural squad and a key member in their charge to win the first title in the new league's history. Yorke was so influential he attracted the attention of Premier League club Sunderland.
Liverpool legend Robbie Fowler made the somewhat surprising decision to head Down Under to play for the North Queensland Fury. He made 26 appearances for the club, but left after a rocky end to their relationship. He then headed across the country to Perth Glory, where he managed nine goals in 28 appearances.
A contentious figure in English football circles, the hulking Emile Heskey struggled to make a lasting impression at Newcastle Jets. Despite his impressive 62 caps for England, he departed Australia having scored just 10 goals in 42 games.
Harry Kewell - Melbourne Victory (2011-2012), Melbourne Heart (2013-2014)
Considered Australia's best ever player, Harry Kewell returned home to Australia in 2011 to play for Melbourne Victory. While he was never able to recapture the form that catapulted him to the top of the Premier League, the Socceroos striker still showed glimpses of his greatness. Harry played out his final season of professional football in 2013-14 after signing with Victory's fierce rivals, Melbourne Heart.
Brazilian international Juninho made 14 appearances for the Sky Blues after stints with Middlesbrough and Atletico Madrid in Europe. Whenever Juninho got on the park for Sydney FC he sparkled. Unfortunately constant injuries limited his game time and once the club decided against giving him a new contract, he retired from football.
French international William Gallas signed as Perth Glory's marquee for the 2013-14 season. Despite his impressive record of 291 Premier League appearances, Perth was not a happy hunting ground for the imposing defender. Injury troubles meant Gallas struggled for consistency and he was not offered another contract at the end of the season.
Former Barcelona striker and Brazilian international Romario joined Adelaide United on a short-term deal that produced four mediocre appearances for one goal. The signing, considered to be one of the worst in A-League history, reportedly cost club owner Nick Bianco $250,000.
The third most capped Socceroo, Brett Emerton returned to Australia after a stellar eight-year career with Blackburn Rovers in the Premier League. He managed 7 goals in 57 appearances for Sydney FC and announced his retirement in January 2014 citing persistent back issues.
Jason Culina - Gold Coast FC (2009-2011), Sydney FC (2012-2013)
Socceroo Jason Culina moved back to the A-League after a decade of plying his trade in the Dutch Eredivisie. His 44-game run with Gold Coast FC was a successful one but a serious knee injury and other issues eventually saw him wind up at Sydney FC. However he walked out on the club in February 2013 following a disagreement with then-coach Frank Farina and retired from professional football soon after.
Socceroo captain Lucas Neill joined Sydney FC on a ten-game guest stint in the back half of their unsuccessful 2012-13 campaign. He was unable to make an impression in the struggling club and injuries limited him to just four appearances.
