Newcastle Jets coach Branko Culina believes the salary cap for A-League clubs is becoming redundant with all the new rules being applied.

Football Federation Australia this week announced new rulings on marquee, guest and youth players which Culina thinks are pointless if the salary cap is to remain.

The new rules are that a second marquee player can be signed by clubs to be paid outside of the salary cap providing that player is Australian-born, the extension in the guest player clause from four games to 10 games including finals and three youth players can now be paid on a minimum wage outside the cap.

These rules have Culina perplexed as to why there is actually a limit on how much clubs can spend on player wages.

"To me, if you're going to bring all of these new rules in - under-23 marquee, marquee Australian, marquee overseas - why have a salary cap?" Culina told the Newcastle Herald.

"It's only natural that if some clubs are going to take up the option of having two marquee players, local and overseas, and others are not, that those that do take it up are going to be in a better position.

"If indeed they [FFA] did introduce the salary cap to keep it all close, this could separate the clubs more than what they already are."

Culina added that he believes the rules will only be an extra burden that most clubs cannot carry.

"The clubs are bleeding very heavily as it is," he said. "I'm not sure that too many can sustain any additional bleeding . . . from a footballing point of view, it's going to put a lot of extra burden on the clubs."
