Former Queensland coach Miron Bleiberg has launched another stunning attack on his former employers by claiming Roar players are overpaid because the club are scared of them getting poached by the Gold Coast.

Bleiberg's new club today announced an unprecedented sister relationship with Chinese Super League side Beijing Guoan FC and unveiled former Australia youth international Jess Vanstrattan and backup goalkeeper Scott Higgins as their inaugural signings.

But the colourful Bleiberg didn't waste the opportunity to sink the boot into the Roar, the club he left in acrimonious circumstances two years ago.

He further heightened tensions with Queensland by claiming Frank Farina's current squad were deliberately overpaid to ward off approaches from A-League rivals, chiefly the Clive Palmer-backed Gold Coast club which enters the league next season.

Gold Coast residents Craig Moore, Danny Tiatto and Charlie Miller could all figure as potential recruiting targets for Palmer, who once again vowed United would win the A-League at their first attempt.

Asked if he was interested in any Roar players, Bleiberg said: "On purpose, I haven't approached one player from the Roar. "They are very scared of us poaching all their players. "A lot of players from the Roar have already got much more money that they deserve to get, so the Roar are wasting their resources which makes them weaker. "But I don't say no. There could be a player from the Roar who does not get a contract and will come and ask 'do you want my services?' I might consider it, but we are not going to be actively asking Roar players.''

In a bold move certain to ruffle feathers league-wide, mining magnate Palmer also revealed the Gold Coast club had already started an audacious raid on rival playing stocks by sending out recruiting pamphlets stating the reasons why players should defect to the Coast.

A-League players coming out of contract in March next year are permitted to speak to other clubs from tomorrow.
