Brisbane have found repeated ways into the attacking box, while Macarthur's compact spells have still left Robinson with substantial work. The first clean shot after a midfield recovery is the central contest. Macarthur can answer through Fraser's delivery and Touré's run, especially when the game opens later.
Russell and Nam give Brisbane a forward connection to Vidic and Postolachi, and their corners bring Aldred into the second contact. Macarthur allowed sustained shooting against Newcastle and Western Sydney, with Robinson making important saves. Aspropotamitis played Macarthur's latest match but is now officially out, removing an observed defensive and set-piece role; Brisbane's Valkanis absence was already part of its recent games.
Macarthur can sit in a block and release Fraser or Touré after a turnover. Brisbane's repeated box entries against that resistance are the stronger route to a decisive finish. That's why I'm siding with Brisbane to win this match.
