All the talk leading into Sunday's Big Blue has been around Melbourne Victory's depleted attack, with as many as four forwards unavailable for the match. The way Sydney FC see it, however, that could make their rivals unpredictable.

Victory will be without Kenny Athiu and Elvis Kamsoba due to international duty while Socceroo Andrew Nabbout is out injured though there is a slight chance Australian international Robbie Kruse could return from injury to make his league debut. The forced changes will prompt Victory coach Marco Kurz into arranging a makeshift forward line comprised of players who won't feature in Sydney FC's analysis footage.

"It always makes it a little bit difficult I suppose, the personnel changes," Sydney defender Alex Wilkinson said. "They have a few boys away on international duty and whether Kruse comes back and plays or not, who knows?"

The only assurance Wilkinson has is that Swedish international Ola Toivonen will be the focal point of Victory's attack. In terms of his other marking duties, he says it is anyone's guess who else he might come up against. It makes it harder to prepare for personal battles but Sydney are confident they have enough of an insight into the attacking patterns, style of play and structure of their rivals which aren't likely to be altered in a short space of time.
