The five year A-League Collective Bargaining Agreement was supposed to be reviewed between October and December 2010 for the 2011/12 and 2012/13 seasons, with any changes to take effect on 1 April 2011.

Professional Footballers Australia has agreed to an extension, acknowledging the importance of the current review.

"The players, like the fans, are very anxious for the current reviews of the CBA and the A-League to be completed as soon as possible," PFA chief executive Brendan Schwab told the PFA's official website.

"Some 80 players will have their contracts expire in just over two months, and they are uncertain about their futures as we wait for FFA to confirm the structure of the A-League for 2011/2012, including whether Fury will continue."

However, the message to the FFA is that a clear picture must emerge sooner rather than later - with so much uncertainty still in the air.

"The one month extension in the CBA review negotiations shows FFA that we remain willing to renegotiate the existing CBA terms should that be necessary," said Schwab.

"At the same time, it is imperative for both fan and player confidence in the A-League that FFA, the PFA and the clubs have certainty as soon as possible. The end of this month is a reasonable timeframe for FFA."

The very first CBA was launched in Sydney in May 2008.

At the launch, PFA president Simon Colosimo said: "“This is a wonderful day for footballers in this country. We have a great platform to move forward in this country and in the world.

“We really appreciate the efforts of both the FFA and the PFA in negotiating and finalising this agreement.

“As players we understand that it’s the longevity of the game that’s important. This shows we’re not just in it for ourselves."
