The Chiefs' advantages are in contrast to the few concessions afforded to the Perth Bears, who will enter the NRL next season. "It's not a level playing field and I think you can see that," said Sydney Roosters coach Robinson.

"It's not your average club, but if players want to go there you can't compete."
