The move marks a softening of the union's stance on the idea of restricting its 4,000 members' wages.

"If those were the conditions attached to improving clubs' financial situation, we may well approve them," chief executive Gordon Taylor said.

Discussions on measures to ease the plight of struggling clubs have taken place between the PFA, Premier League, Football Association and Football League.

One proposal to emerge from the talks is cash aid tied to the imposition of a salary cap and tighter financial controls.

Taylor said: "The term salary capping is emotive because people think of a maximum wage.

"But we do not want clubs to be spending more than they have.

"If they started talking about a ceiling on the amount that goes out to players then we would talk about it.

"We are not against good accounting," he told The Times newspaper.

The PFA has previously been strongly opposed to the imposition of a salary cap.

But the worsening financial climate in the game has prompted a change of attitude.

Players are already being forced to take pay cuts.

And the union has said it cannot afford to hand out any more emergency loans to meet struggling clubs' wage bills.

Another option on the League's agenda is divisional contracts under which a player's salary rises or falls with promotion and relegation.

But Taylor believes that a player may feel entitled to a move if his wages are cut.
