Two A-League clubs, Adelaide United and Queensland Roar, are facing financial difficulties and may be forced to hand their licences back to Football Federation Australia.

Owners of the clubs are struggling in the current economic climate and the only option may be to hand over control to the football's governing body in the FFA.

In the Roar's case, an expensive agreement with the Queensland State Government to rent Suncorp Stadium has had a debilitating affect on major owner Laurence Oudendyk's finances.

In Adelaide, primary investor Nick Bianco has withdrawn his support from the club because of a tight economic status and it seems that licences will not be sold back to the FFA, but simply taken.
