The ex-Socceroo believes the additions of Adam Taggart and Stefan Mauk alongside existing talent such as Henrique and Eric Bautheac has given him a license to make the Roar an attacking force.

Add in Danish international Tobias Mikkelsen and Spanish midfielder Alex Lopez and Aloisi is promising his team will be one of the most eye-pleasing in the competition.

"The way we're going to play our football will be exciting to watch and I'm sure they'll be happy when they see us on Sunday," Aloisi told reporters on Friday.

"What everyone's going to be excited about is our front four ... I know it takes a while for chemistry to build but our players have been here from very early on.

"You can really see the last two or three weeks the understanding's really grown and they're enjoying playing with each other."

The Roar begin their campaign at Suncorp Stadium on Sunday against Central Coast.

The Mariners will be led by former Roar coach Mike Mulvey and, while the attention in Gosford has largely been focused with on-trial ex-sprinter Usain Bolt, it's another Mariners recruit that has Aloisi concerned.

"We've got to make sure that we stop their crosses because they've got players like Tommy Oar who will cross the ball," Aloisi said about the ex-Roar winger.

"We know him very well because he was here with us.

"I'm pretty sure that people recognise he's a top player and we just have to make sure we're ready for him."
