Speaking on Wednesday morning, Glory coach Dave Mitchell confirmed the 36-year-old had passed all the required fitness tests the club has given him since he paid for his return to Perth a fortnight ago.

Mitchell said the club had no issue with Amaral's suspect hamstrings, despite having seen the Brazilian suffer a serious hamstring injury in Round 4 last season that ultimately curtailed his entire campaign.

And he said the club was attempting to rush through paperwork allowing Amaral to join the squad for nine matches under the league's guest player rules, starting possibly on Friday if his application is approved in time.

"We've had him tested, fitness wise and we've had his hamstrings tested as well so in that, things are looking okay," Mitchell said.

"He's looking good, so we're looking to get some paperwork done for him and there's a good chance that could be done in the next few days."

After struggling to get his expensively-assembled side working cohesively over the first two rounds, Mitchell was happy with their progress in the 2-0 against the Jets, although he concedes Glory still need to work on creating and converting more chances.

Mitchell said the club's defence had been solid for the first three rounds, conceding just one goal from general play, but said the back four faced its toughest test this week against Victory's quality attacking players in Archie Thompson, Danny Allsopp and Carlos Hernandez.

"They've (Melbourne) not had the best of starts but they're very formidable," Mitchell said."They've got three great strikers there.

"If you drop your guard, you just saw last week North Queensland weren't paying attention and they got in there behind them and bang, they scored 1-0.

"So they're always a threat with those strikers and they're very well organised, they're a good side."
