Three overseas clubs have targeted signing Josh Ridson after the fullback's displays for Australia in the 2018 World Cup.
Risdon has played the full 180 minutes in the Socceroos' duels with France and Denmark.
FourFourTwo understands that three foreign clubs have enquired about the fullback's availability.
One is in Turkey, one is in the Russian Premier League and the other plays in continental Europe.
Risdon is set to start again on Tuesday in Australia's crunch clash with Peru.
The Bunbury-born defender came through the Western Australian National Training Centre and debuted for Perth Glory in 2010.
He made 142 first-team appearances for Glory before joining Western Sydney last year.
The 25-year-old is signed to the Wanderers until the end of the 2018/2019 A-League season.
