ADELAIDE defender Milan Susak revealed he has partnered skipper Jon McKain just five times in training.

Susak's revelation may have underlined one reason why the Reds' form is erratic, with five of its preferred starting XI not regularly training with the group due to injury.

A groin strain forced Susak to sacrifice an opportunity to impress at Socceroos coach Holger Osieck's 48-hour camp, which ended last night. McKain has been battling a knee complaint.

"I'm disappointed but then again hopefully I get a chance again," Susak said.

"My groin is actually all right now. If I went to Sydney there could have been a risk of me injuring it again.

"The Socceroos were going to play a match against the Olyroos and with that not being an easy game it might have been too much for my body before we play Brisbane."

Evgeniy Levchenko's calf problem and Socceroo Dario Vidosic's limited time on the training track due to niggling injuries, including a corked thigh, ended their training sessions early yesterday.

Add Zenon Caravella's Achilles problem and Bruce Djite's adductor injury and coach Rini Coolen may be in the midst of a crisis before facing Brisbane at Suncorp Stadium on Friday night.

The injury concerns may be one reason why there seemed to be much midfield confusion as the Reds' shape was pulled in different directions during the 2-1 loss to Sydney FC last weekend.

Susak said Adelaide was prepared to cop last weekend's nightmare loss on the chin, with Roar looming as the club's greatest challenge to reversing its inconsistent form.

Susak - one of Roar boss Ange Postecoglou's disciples in the side's run to the premier's plate and grand final win - believes Brisbane is beatable despite not tasting defeat for 13 months. "Anything's possible. We'll give them a good match," he said.
