Former Socceroos defender Robert Cornthwaite will return to the A-League on a two-year deal with Western Sydney.
Cornthwaite, who played 103 games for Adelaide between 2005 and 2011, has spent five years playing in Korea and Malaysia.
"I've been away from Australia for a while but I watched as much A-League as possible ... and Western Sydney have been very successful and played some very good football," Cornthwaite said.
"I'm looking forward to getting in, pulling on the Red and Black and getting to work as soon as possible."
Cornthwaite will form part of a new-look Wanderers defensive unit which will also include recently recruited Soabusg defender Aritz Borda.
The 30-year-old played eight games for the Socceroos between 2009 and 2013, scoring three goals.
