In what appears to be another raspberry blown at Football Federation Australia (FFA), Gold Coast United boss Clive Palmer has challenged the Olyroos to take on his under-23 outfit in a $50,000 "winner-takes-all clash".

Palmer is again on a crash course with FFA boss Ben Buckley after seeking to have the big bucks game played in order to highlight selection flaws in the Olyroos' doomed London Games qualifying campaign.

"I'm prepared to put up $50,000 for the winning team, which I am confident will be the Gold Coast," Palmer said in a statement.

"We have won the National Youth League for the past two seasons and a lot of these guys have now made their mark in the A-League.

"I'm sure our boys would give the Olyroos a good hiding and show what could have been achieved had there been a fairer selection system."
