Ryan Edwards, 19, joins his father and brother Cameron at Glory, while Sciola has inked a one-year deal after impressing during a trial.
 
Alistair Edwards took over at Glory in February and has spoken openly about his desire to bring Western Australian talent to the club.
 
He was delighted to welcome Young Socceroo Ryan to the club and believes he will add to his team's attack.
 
"We've had a philosophy within the group to try and entice WA players back here," Alistair Edwards said. "Luckily Reading have agreed to let him stay here for the entire season and that's great for him.
 
"Ryan has been playing with the Under-20 national team for the last four years and was a part of the recent World Cup campaign as well.
 
"He's a very dynamic kind of player. He's attacking and brings a lot of energy to the team and he's grown up in an environment where he fits into our philosophy 100 per cent.
 
"He's come along now after two years in England, so he's come back a lot more experienced and it's great that we've got another WA player back playing for Perth Glory.
 
"Ryan will be able to develop in our environment which is better for us, for him and for the game in general."
 
Sciola, 26, joins Glory after a spell in Cyprus, most recently with Alki Larnaca in the top flight.
 
Alistair Edwards was impressed by Sciola during a trial and expects his new signing to play anywhere across the front line.
 
"Sidnei has come along and trained with us for the week and done some very good things," he said.
 
"I'd heard some really good things about him before he came to the club, but I wanted to see what he was like off the field, how he would fit into the culture of the group.
 
"His footballing ability was unquestionable and now we've found out what he's like as a person and he most definitely fits into our culture.
 
"He's a brilliant guy. I know it's a bit of a cliché, but he'll bring some Brazilian flair to the side, that's for sure.
 
"He's very exciting, he plays on the left-hand side as a number 11, but he can also play on the right and as a central striker.
 
"He brings a bit of sparkle and if I wasn't the coach of the team, I'd be buying a membership to come and watch him play."
