Sydney captain Brett Kirk is backing struggling Swans star Adam Goodes to quickly rediscover his top form.

Kirk echoed coach Paul Roos' comments from last weekend that the dual Brownlow Medallist was underperforming, but he believed Goodes is only a game or two away from finding his trademark brilliance.

"There's a lot of expectation on Goodesy, he's an important player to us," Kirk said on Wednesday.

"He does get the best run-with player each week and that's something he has to deal with.

"I guess if you're up and down with your form, you tend to try work your way into games.

"And I think that's not far away for Goodesy. We saw his form in the second half of last year was super and we're just waiting for him to get back into that form."

Kirk said Goodes would have the full support of his teammates during his uncharacteristic slump.

"We don't rely on any one player so for Adam to be a good player for us all we want him to do is play his role in the 22," he said.

"He's been working hard in games.

"The expectation's on him because he's a very good player.

"The playing group will support him, he's very important to us and that's all we can do."

Kirk described his side's 42-point loss to the Cats last week as "ordinary".

"I think we showed some really good form in the Geelong game, barring the last quarter," he said.

"We didn't think, especially the second and third quarters, that we were really that bad, we thought we matched them ... the last 30 minutes at the weekend was disappointing."

Ruckman Peter Everitt is in contention to play his first senior match of 2008 against the Kangaroos at Telstra Dome on Sunday after recovering from a knee injury.

Kirk is pleased with how the fourth-placed Swans' season was progressing and said the younger players were stepping up in the absence of Barry Hall and Tadhg Kennelly.

"We're looking forward to playing the Kangaroos, a hardened type team, similar to Geelong so it'll be a good match," he said.

"I think Kangaroos are a really good side, they're right up amongst it.

"We're really looking forward to the contest.

"They've shown last year and they're showing again this year that they're a consistent team and they're going to be up around the mark."
