Brisbane Roar will be on high alert against Central Coast wingers Fabio Ferreira and Mitch Austin when the teams meet in a top-of-the-table clash at Suncorp Stadium on Sunday.
Ferreira and Austin were the heroes for the Mariners in their 3-2 win over Perth last Saturday, with Ferreira netting twice and causing plenty of problems down his right flank.
Roar star Thomas Broich admitted he would have his hands full trying to contain the former Adelaide United sharpshooter.
"He's electric - he's hard to contain, and it's up to us to keep the ball and not allow the players around him to feed him," the dual Johnny Warren medallist said.
One thing in the Roar's favour is its increased fitness levels this season.
The men in orange kept pace with the Wanderers all game in their impressive season-opening 3-1 win last Thursday night.
"The Wanderers are traditionally known as the fittest team in the league, or up there, and I certainly felt we could have easily matched them there," Broich said.
The Roar displayed plenty of attacking firepower in its 3-1 trial win over Central Coast, but Broich said he saw plenty of positive signs from the Mariners under new coach Tony Walmsley.
"I was very impressed with the Mariners' playing style. It's a physical counter-attacking style - defensive minded," Broich said.
"They're winning the ball quite well."
Roar stand-in central defender Daniel Bowles said it was a thrill to be lining up behind playmaker and Spanish recruit Corona, who impressed in his debut against the Wanderers.
Bowles headed home from one of two Corona corners which led to goals against Western Sydney.
"He (Corona) is a sensational player. He hasn't been with us long, but he's already played 90 minutes and didn't look out of place," Bowles said.
"He was one of the better players on the park, and his delivery off set-pieces was really high quality."
Bowles has been playing in the central defence in the absence of the injured Luke DeVere and James Donachie.
He has been enjoying his time in that position, and said he was confident Brisbane's defenders would show further improvement after letting in a first-half goal against the Wanderers.
"It's only early days but we (the defenders) are slowly developing. There's definitely room for improvement - it got better as the game progressed (against Western Sydney)," Bowles said.
