Melbourne Victory coach Ange Postecoglou has said that Mark Milligan is an important part of his plans for the club.
The Australia international is reportedly a target for several club during this transfer window, including Queens Park Rangers.
Postecoglou told the Herald Sun: "He's got two years to go with us [on his contract] so it's as much our decision as anyone else's.
"With every good performance he has at national level I guess his value goes up for ourselves and for anyone else that wants him.
"He's very much a very important part of what we're about and what we want to create."
The defender has won 20 caps for Australia.
