Last season’s champions sit second  last  on the ladder after the first two months of the competition, having slumped to a 2-1 loss to second-placed Central Coast Mariners on Sunday in Gosford.

Brisbane conceded the decisive goal in the 81st minute to Mariners midfield maestro TomRogic.

Vidosic was not buying into his team's on field protestations that the ball was out as Mariners Michael McGlinchey headed back towards Rogic, with the 51 year-old coach instead lambasting his team.

"I don't know what to think, from where we were sitting you can't see if the ball was out, but what you can see is that it's a free kick," Vidosic said.

"It's hit past to the far post - that means it's the longest distance it has to travel and the smallest player, probably apart from Massimo Murdocca, the second-smallest player on the park wins the ball and heads the ball back.

“So who is marking who? It’s just kindergarten stuff. It’s what we deserved - you can’t come here and defend like that for set pieces, it’s just not on."

Vidosic made it clear Brisbane players were not maintaining the standards of the two-time championship outfit.

“Players need to have a good look at themselves. I can't go out there. They have all got instructions about what they need to do and if I tell you to mark him that's all that you need to do. You stay with him, you follow him," he said.

"If he goes to toilet you go with him to the toilet. It’s simple as that."
