Sydney FC playermaker Nicky Carle believes Brisbane Roar’s recent dip in form was an indication of the A-League’s even playing field, with every club capable of challenging for top honours.

Ange Postecoglou’s men were overhauled 2-0 by Wellington Phoenix on Wednesday night, confining the club to its third successive loss, after falling short against Sydney and Melbourne Heart.

Central Coast Mariners has taken advantage of Brisbane’s hiccup, now equal on points with the reining champions at the top of the table. The Roar inscribed its name in the record books after going on a 36-game unbeaten run, before being shell-shocked 2-0 by the Sky Blues.

"A few weeks ago everyone would have told you that Brisbane are going to win [the title] hands down," Carle admitted.

"After their disappointing three games it's just given everyone that bit of hope and put everyone back in the running.

"The competition has definitely opened up ... although I do think they are a very good side and will bounce back."

Sydney will encompass a strenuous test on Saturday, when it travels to Newcastle, who has an ominous record on home test. The Sky Blues will be looking to resurrect their campaign after a lacklustre scoreless draw against A-League cellar-dwellers Gold Coast United last weekend.

"It was definitely frustrating after the performance against Brisbane," Carle revealed.

"We all know we've got to do better and that it wasn't up to our standard."

The former marquee player in the Hunter Valley professed there was no ill-feelings after his departure from the Jets.

"I enjoyed my time there but the most important thing for me is to get the three points for Sydney and help us climb up that ladder," he said.
