Thwaite has been a key player at Glory since arriving in Perth in 2012.

The 31-year-old will take over as captain from Jacob Burns, who retired at the end of last season.

Perth only narrowly avoided the wooden spoon last season, but is aiming to make the finals this campaign after luring the likes of Andy Keogh, Youssouf Hersi, Mitch Nichols, Ruben Zadkovich, Diogo Ferreira, Richard Garcia and Dino Djulbic to the club.

Glory were beset by infighting last season, with a player-led revolt eventually leading to the downfall of coach Alistair Edwards.

New coach Kenny Lowe has been well-received by the players, and the club is optimistic they can challenge for the title this season.

Thwaite was unveiled as the new Glory captain on Thursday, with the 31-year-old taking over from retired midfielder Jacob Burns.

"None of that (fractures) exists right now," Thwaite said. "We're making a conscious effort to change things this year.

"We just need to focus on winning, and then those problems won't occur. If you're losing games, there's always going to be someone who's not happy.

"This happens in every single club in the world."

Although the bookies have written off Glory's title chances, Thwaite said the club should be aiming high.

The much-needed bolstering of Glory's medical department will help the team's cause.

"I'm sick of seeing the success of other teams and watching the ACL and grand finals on TV," Thwaite said.

"I haven't won a championship since I was at Melbourne Victory, which was five years ago.

"We want to win something this year. We want to be part of the Asian Champions League."

Glory kicks off its campaign away to Wellington Phoenix on Sunday, with winger Sidnei set to miss the first three rounds due to a calf injury while Zadkovich is also unavailable.
