Vidosic blasts 'kindergarten' defending

Brisbane Roar coach Rado Vidosic has blasted his team’s poor attention to detail after their fifth loss of the season.

Brisbane Roar coach Rado Vidosic has blasted his team-s poor attention to detail, labelling their defence ‘kindergarten- style after their fifth loss of the Hyundai A-League season.

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 the second-placed Central Coast Mariners on Sunday in Gosford.

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

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, 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," Vidosic said.

“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.

In addition to the lapses at set pieces, Vidosic identified other areas of concern.

"Our biggest problem is in transition. We don-t drop back, we are not aggressive. We can defend when the ball is in front of us but the moment the ball goes behind us, or behind our first defensive line, people are walking," he said.

"So we just need to have a good look at ourselves and try to correct those little mistakes.

The one-time Roar assistant coach also noted the improvement needed in attack.

"We need a little bit more responsibility in the front third. I felt that maybe Ben Halloran could have done better, he had a couple of chances when he broke inside the penalty box, maybe he should have tried to have a shot or pass," he said.

"We need to look at individual things that we can improve over the next few weeks."

The Roar face Newcastle Jets at home next weekend, with the Hunter Valley side coming off a 3-3 draw with the Heart in Melbourne.
