Brisbane Roar will be on alert in defence on Saturday night as they look to ensure Adelaide United's search for an A-League goalscorer this season continues for another week.
The only two goals the misfiring Reds have scored across the competition's first three rounds were own goals, with the side's former attacking potency nowhere to be found under rookie coach Guillermo Amor.
The return of striker Bruce Djite should help them recapure their old spark, but they'll face a Brisbane outfit that has spent all week trying to plug the holes at the back that were exposed so ruthlessly in Wellington last Sunday.
Having leaked five goals already this season, the Roar's defenders recieved a midweek bake from assistant coach Ross Aloisi that would still be ringing in their ears.
His older brother, head coach John Aloisi, joked: "That was nothing. Ross can get a lot angrier than that."
"The players sometimes want to be told if they're not doing the right job. They've taken it on board, they've been good.
"Not only with what we did on the pitch, we showed them analysis. I've got a group that's wanting to learn and improve every day."
Aloisi views a watertight defence as Brisbane's missing piece, with the rest of the team in rude health and the likes of proven A-League performers Luke DeVere, Henrique, Jean Carlos Solorzano and wildcard Spanish import Javier Hervas still to come.
"It was hard to take last week, especially when you dominate a team so much," he said.
"We looked back at the game and we had 14 shots to their eight, 61 per cent possession. In terms of our performance as a whole, that was one of our better ones."
Meanwhile, the Roar's star midfielder Corona says he is "very happy" with life in Brisbane.
The 34-year-old had never played outside of Spain's top two leagues before his A-League switch, but has already emerged as one of the competition's most cultured players.
"The teammates are excellent, they help me in everything with my family, with my language, with my play too," said Corona, who will lock horns with several of his compatriots at Suncorp Stadium.
"I enjoy it very much, the play in the A-League.
"There's many chances to score. Physically, the players are very strong and fast as well. But it's very spectacular for the supporters."
