Asian Champions League winning coach Tony Popovic will remain at Western Sydney Wanderers next season and beyond after signing a contract extension as early as Friday.

The Wanderers won the battle to retain the services of their foundation coach, who was linked with moves to Asia and Europe in recent months but agreed to terms for a new deal.

Despite a year remaining on his existing deal, the Wanderers made an early move to ensure Popovic's future remains in Parramatta amid heavy interest from Croatian giants Hajduk Split, as well as past offers from clubs in China, Korea and England.

The Wanderers agreed to personal terms with Popovic, who was present with chairman Paul Lederer and chief executive John Tsatsimas for Friday's announcement.
