Sydney FC are set for an attacking boost this weekend, with both Alex Brosque and David Carney set to be named in the starting XI.
Brosque, who has been battling a hamstring injury, has managed just one match in the past two months, but he is finally fit to reclaim his spot in the side.
"His preparation has been good, I think having him back training fully has given the team a lift," Arnold said on Thursday.
"Brosquey has played at number nine in two games before he got injured. At Newcastle, he scored and we were outstanding that game.
"Then he played for 25 minutes against the Mariners and when he went off we were up 3-0.
"In the A-League salary cap system, if your marquees aren't playing it can hurt you… Brosquey is our marquee and he brings a lot of quality to the team."
Alongside Brosque will be new recruit David Carney, who will also start for Sydney, coach Graham Arnold confirmed.
"The opposition look at (Carney) and fear him, because of his reputation and what he can do," Arnold said.
"Straight away you put their right full-back on the back foot, because he's worried about going forward because if they lose the ball Carney is there. And Carney can hurt them.
"We're in the position now where we've got that sort of player that can hurt them. David is probably someone that if you give him the ball he can change a game."
The Sky Blues take on Perth Glory at Allianz Stadium on Saturday at 5.15pm AEDT.
