Former Glory striker Maclaren is Roar’s trump card in a crunch clash, having scored against his former club in the past three A-League encounters between the two clubs.

Third-placed Brisbane holds a two-point buffer ahead of fifth-placed Perth with the match likely to go some way to determining finals placings with eight rounds to play.

Maclaren exited Perth in 2015, frustrated by a lack of starting opportunities despite scoring nine goals in the 2014/15 campaign.

“They have to catch Jamie first,” Aloisi said, when asked about Perth’s ‘physical’ style.

“Jamie Maclaren loves playing against Perth Glory, for whatever reason, I don’t ask him.

“I just let him go out there and score goals. Hopefully he does the same again.”

Aloisi ruled out injured duo Corey Brown (hamstring) and Jack Hingert (ankle) from Saturday’s clash, although the latter is likely to recover for Tuesday’s AFC Champions League home game against Muang Thong United.

Youngster Connor O’Toole could get a chance against Perth.

One player who won’t line up against Glory is new Greek signing Avraam Papadopoulos who will arrive in Australia on Saturday.

The Roar boss said the former Greece international was a major addition and was unfazed by his links to match-fixing allegations in 2011 while with Olympiakos.

“It’s not a concern. It was five years ago and they were allegations,” Aloisi said.

“Lucky enough I know quite a few people in Greece and I’m able to ask what he’s like as a person and he’s a good person. That’s what we want at the football club.

“He’s an experienced player who’s played in Asia which is important for us with the Asian Champions League.

“Also he’s captained a massive club in Olympiakos. He’s not only a good player, but he’s a good leader.”
