THE AFL Players' Association is not concerned if it fails to agree to the AFL's final offer on a Collective Bargaining Agreement by its September 15 deadline.

The League presented a $1.144 billion package over the next five years to the AFLPA late last month, with AFL chief Andrew Demetriou saying he was confident the deal would be finalised within the timeframe.

However, AFLPA general manager of player relations Ian Prendergast told Melbourne radio station SEN on Tuesday that the association would not be rushed into reaching an agreement.

"We've taken our time to analyse the offer the AFL have put to us in consultation with players, delegates and board members to discuss our options in detail - we're in the process of finalising what our response will be," Prendergast said.

"Hopefully we can meet that [September 15] deadline, but if it takes us a little bit longer, so be it."

The main sticking point has been the AFL's refusal to meet the players' demands of a fixed share of AFL revenue, a demand Demetriou said in May was "a lazy way of doing business".

Instead, the League offered a rise of $333 million from the last CBA and doubled retirement contributions from $36 million to $72 million.

"We've compromised on both sides, we've exercised a willingness to compromise and it may be there needs to be a further compromise made from either side," Prendergast said.

"It's pretty complex in terms of the number of claims on the table."

Following Tom Scully's defection to Greater Western Sydney on Monday, Prendergast was asked if Scully's reported $6 million six-year deal had created an unreasonable expectation on salary.

"I don't think so; our negotiations have been based on what players have received historically. You could argue it has an inflationary effect, but I don't think it's affected the negotiations," Prendergast said.

"However, it has complicated the negotiations in terms of the AFL's economic model. They have had to establish these two teams (Gold Coast and Greater Western Sydney) financially and ensure they're viable."
