The Australian soccer players' union says it will take legal advice over its industrial options following the breakdown of talks between it and the game's governing body, Football Federation Australia, on a new collective bargaining agreement.

Professional Footballers Australia, which argues it has accepted wage restraint for the past four years, is incensed that FFA wants to freeze the salary cap of $2.55 million for at least two more years.

The existing CBA expires next Tuesday, and if FFA insists on imposing its salary cap settlement without agreement, the union argues it will have little option but to take legal counsel.

"We have no further talks scheduled and this is the major sticking point on a new deal," PFA chief executive Adam Vivian said on Thursday night. "We are seeking a six-year agreement which has vision and scope to grow the game, but we cannot accept this kind of wage freeze after several years of wage restraint and limited salary cap increases.
