The Socceroo veteran's return comes just days after Harry Kewell's signature on a Melbourne Victory contract and joins Jason Culina at Newcastle Jets and Dario Vidosic at Adelaide United.

It's the latest blockbuster addition to what now promises to be a sizzling season.

Emerton learned his football in the junior ranks in Greater Western Sydney and was a star for Sydney Olympic in the former National Soccer League.

“Brett Emerton is the quintessential football success story,” said FFA CEO Buckley.

“He developed on the fields in football’s heartland in Sydney’s west, before a spectacular spell in the NSL in his home town then great success in Europe and on the international stage with the Qantas Socceroos.

“Sydney FC has found the ideal marquee player and a wonderful ambassador in Brett Emerton. On behalf of the football community, I congratulate Sydney FC on securing Brett’s signature and I’m delighted to say ‘welcome home, Brett’.”

In terms of connecting the Hyundai A-League with the grassroots of the game, Brett Emerton embodies the compelling story of football’s burgeoning participation base, the technical development pathway and the professional career opportunities that football provides, said the FFA chief.

“Sydney is a hugely competitive sports marketplace with over 20 professional teams, but Sydney FC now has a new advantage with the credibility, profile and character that Brett Emerton will bring,” said Buckley.

“Let’s not forget that Brett is leaving the English Premier League at the top of his game and will add pure football class to the Hyundai A-League.”
