Bobo will join recent re-signing, club captain Alex Brosque, in the squad that travels to Perth, as Arnold rejoiced at having the Sky Blues’ number 14 back for a further season.

“Bobo is settling in well and we expect him to play tomorrow night,” Arnold said.

“Bobo is a player with a fantastic pedigree and great CV. He’s a fantastic guy, he’s fit in perfect, we’re expecting big things from him and I’m sure he’ll deliver.”

Arnold added: “Brosque has worked extremely hard in the offseason to get fit and he’s looked great at training.

“His absence last year showed how important he is to the team and the club, and I know he’s a fan favourite at Sydney FC. He is Sky Blue through-and-through so it’s fantastic to have our leader back.”

The Sky Blues are looking to reach the quarter finals of the cup for the second time, and have never lost a game away to the Glory under the tutelage of Arnold.

The Sky Blues’ boss has his sights set on claiming all three trophies on offer and Tuesday night presents the next step in achieving that goal.

“(Tuesday’s match is) hugely important, there’s a trophy on the line and we want to be challenging for all three trophies this year,” Arnold said.

“It’s a game we’re looking forward to. We’ve always had quite good success over there in Perth but it’s going to be a tough game.”

Arnold said an all A-League encounter presents different issues to those against National Premier Leagues teams.

State-level teams are often fitter at this stage of the competition as it coincides with their leagues, while Perth will be at a similar fitness level to the Sky Blues.

This, coupled with both teams’ history in the cup, means Tuesday’s clash will be a spectacle of attrition.

“It’s three weeks ago now that we played Wollongong and we’re three weeks further down the track, fitness-wise,” Arnold said.

“At this stage in the FFA Cup, playing away against state-league teams that have got 20-odd games under their belt, they’re more match hardened than the A-League teams.

“But coming up against Perth, the fitness levels of both teams will probably be very similar and it’ll get down to the best performer on the day.”

Sydney FC ran out 4-0 winners last time the two teams met thanks to strikes from David Carney, Filip Holosko, Ali Abbas and Milos Ninkovic.
