Glory focus is Reds, not transfer window

Perth Glory captain Richard Garcia would love to have striker Andy Keogh available this weekend against Adelaide United but the midfielder isn't losing sleep over the club's transfer activity.

Last month, Keogh signed a two-year deal with the Glory that starts before the 2016-17 A-League season but Perth are still working on getting him registered for the rest of the current campaign.

Perth's problem is that they've already filled their five import spots and will need to get rid of another foreign player before Keogh can play.

There has been some speculation that one of injured striking duo Guyon Fernandez and Sidnei could be released this week if the Glory can come to agreement with either player, which could make Keogh available for selection against the Reds on Saturday.

"Andy would be a fantastic addition," Garcia told reporters on Tuesday.

"You know, we need a few more goals, so to have a striker like him come in would be fantastic."

Keogh scored 12 goals in 27 games for Perth last term but left the Glory after the salary cap scandal that rocked the club in 2014-15.

But Garcia denied his squad will lose focus thinking about the potential return of the 29-year-old striker.

"You've got one eye on [the transfer window] but really you're concentrating on the weekend, you've got to prepare for the weekend," the skipper said.

"You don't really have time to sit back and think 'What if? What if? What if?'

"So if things come and things happen then it's a bonus or a negative or whatever, but as a bunch of players, you're just trying to get ready for the game."

One player Garcia and Co. can rely on against Adelaide will be marquee Diego Castro, who has scored three goals in Perth's last four matches.

The Spanish attacking midfielder has seemingly turned the corner after a sluggish start in the A-League, although Castro insists he can get even better.

"My experience in Perth at the moment is really good," Castro said.

"I need more time but now I feel really good."
