Liverpool striker Harry Kewell is threatening to quit international football in a row surrounding his agent Bernie Mandic.
FIFA have asked to see the paperwork following Kewell's £5 million sterling transfer from Leeds with controversy over Mandic's part in the deal.
Kewell, who is recovering from an ankle injury, reckons the complaints are the result of jealousy and pettiness in his native Australia.
"If Soccer Australia is going to let agents that they control to get away with using me to big-note themselves, then they can forget it, there is no point playing for them," he told the Agenewspaper in Australia.
"I'm not there for people to play their silly little games. If Soccer Australia can't protect their own players from this sort of garbage, then why should I bother?
"It's always the same old stuff in Australian soccer. A bunch of nobodies trying to be somebodies at someone else's expense. Well, it ain't going to be at mine," he said.
The Agereports it has seen a letter sent to Kewell from the Football Association in England.
Chris Tanner, an executive of the Australian Licensed Players Agents' Association, maintained he sent the complaint as an individual, not as a representative of the group.
