Former Rangers midfielder Charlie Miller is uncertain of his future with Gold Coast United.

The 34-year old joined United from Brisbane Roar last season and was a key player for the Gold Coast club in the latter stages but they are now finding it hard to fit him into the salary cap.

Miller feels that Football Federation Australia is trying to freeze him out from playing in the A-League.

"I don't know what I've done wrong. I've helped the league. I enjoy the game and feel I bring something to the competition," Miller said.

"There seems to be an agenda there against me for some reason. Every time I talk to an A-League club I get the message that the FFA doesn't want me there. I try and have fun and certain people at the FFA don't seem to like that in me."
