With regular first-teamers Clint Bolton and Alex Brosque both expected to miss the match due to injury, Kosmina has turned to experience to fill the breach in his extended squad.

After recently taking over as senior goalkeeping coach at FC, English Premier League veteran John Filan will make a temporary comeback from retirement, pulling on the gloves as backup keeper to Ivan Necevski, who’s likely to take Bolton’s place in the team.

While Brendon Santalab is expected to step into Brosque’s starting spot in the midfield, former Adelaide United player, Bobby Petta will also make the trip to Perth after signing on this-week with Sydney for the remainder of the season as a long-term injury replacement for American striker, Mike Enfield.
