Earlier this month, it was revealed that Keane would leave Los Angeles Galaxy and a number of clubs around the world were soon linked with the 36-year-old's signature.
A possible destination for Keane is the A-League in Australia, and Brisbane Roar managing director Mark Kingsman has confirmed that his side will bid to sign the forward.
Kingsman told The Age: "When you've got somebody of Robbie Keane's calibre and pedigree, I'm sure every A-League club would be interested. We haven't made an approach yet [but] we will make the call."
Keane has also been linked with clubs in Ireland, England, China and other teams in the MLS.
