The Brisbane Roar have regained their confidence and are ready for an attacking examination from Adelaide, according to winger Dimitri Petratos.

Brisbane Roar winger Dimitri Petratos says the A-League leaders have their confidence back for Sunday’s attacking frenzy against Adelaide United.

The Roar snapped out of their late-season rut with a 3-1 victory over the struggling Perth Glory last weekend but face a much tougher test against the resurgent Reds at Suncorp Stadium.

With Fabio Ferreira in top form, Adelaide have scored 13 goals from their past four matches to three wins that have pushed them to third on the competition table.

Josep Gombau’s men also travel to Brisbane with a strong recent record at Suncorp, where they upset the Roar 2-1 thanks to an injury-time winner by substitute Jordan Elsey.

“It will be a tough game,” Petratos said. “It will be back and forward so we have to make sure we stay strong in defence.”

Brisbane have failed to beat Adelaide at home since their record 7-1 rout in 2011 when Besart Berisha finished with four goals.

Coach Mike Mulvey believes Socceroos duo Matt McKay and Ivan Franjic will have little trouble backing up from Thursday morning’s (AEDT) friendly with Ecuador in London.

While Glory mentor Kenny Lowe felt Perth played the Roar back into form last Friday, Petratos said the last-start win was reward for their hard work following back-to-back losses to Newcastle and Melbourne Heart.

“We got the win which was great and a lot of boys got their confidence back and everything is going really well,” the right-sided attacker said.

“(Mulvey) was very happy. We worked hard in the game and got the result.

“We got three goals and that was great, three different players scored, and the team is working hard.”
