ADELAIDE believes its attacking prowess can crack Fremantle's renowned defensive wall in Saturday's game.

But the Crows are wary of Dockers coach Ross Lyon throwing a curve ball in what looms as a rain-soaked AAMI Stadium battle.

Adelaide beat Fremantle three times last season, including a semi-final victory which ended the Dockers' season.

"We were the only team that beat them from about round 13 onwards, so we're confident that our game style is sufficient enough to get it done," Crows assistant coach Mark Bickley told reporters on Friday.

"But we understand that when you beat a team a couple of occasions in a row, it's unlikely they will come back and play exactly the same way. So there will be some adjustments that they make."

Bickley said Adelaide's success against Fremantle was based on a simple premise.

"You can't afford, when you play Freo, to be safe. You really have to attack," he said.

The Crows will field the same side for the third consecutive week, with Bickley saying heavy rain forecast to continue through Saturday was unlikely to prompt a late change.

Adelaide climbed into the top eight for the first time this year following its one-point win against North Melbourne last Sunday, but the jury remains out: the Crows' five wins have all been against sides outside the top eight.

The fourth-placed Fremantle, who regains winger Stephen Hill from a thigh strain, has conceded the fewest points of any club this year.

"Ross Lyon's trademark is that he's able to get everyone on the same page," he said.

"One of the things about a really strong press or defensive unit is if one or two people aren't committed to it and aren't in the right spot and don't support their teammates, then it all falls apart and teams go straight through and they score really heavily.

"That is the strength of Fremantle - that everyone is really tight, really united and on the same page.

"That doesn't sound very difficult, but I assure you, it is.

"They have had to introduce, through injury, six or seven new players who have just jumped straight into that system and been able to hold up exactly the same ... that is why they're so good."
