West Coast will add the element of unpredictability to their midfield group in a bid to throw Port Adelaide off course in Sunday's AFL clash at Patersons Stadium.

Eagles on-baller Daniel Kerr played his best game since 2007 in last week's win over Adelaide, regularly sharking ruck taps from Nic Naitanui and Dean Cox at pace in a 27-possession, best-afield effort that also featured nine clearances.

Kerr is expected to receive close attention from Power tagger Kane Cornes on Sunday as Port strive to halt West Coast's midfield drive.

But Worsfold has backed midfield coach Scott Burns to come up with some innovative plans to counter Port's negating tactics, claiming Luke Shuey, Mark LeCras and Matt Priddis could wreak havoc if the Power focused too heavily on Kerr.

"I think Matt Priddis is pretty happy with all the attention on Kerry; no one's noticed his 450 clearances in the last 12 months," Worsfold said on Thursday.

"He (Priddis) got enormous treatment on the weekend by the Adelaide players.

"And that's probably why Kerry was happy.

"Now this week it might be the opposite. And that's great for us in terms of building two elite clearance players and we believe down the track we'll have four or five."

The Eagles (7-4) are just four points adrift of fourth spot, but Worsfold said it was too early to start dreaming of a top-four finish just yet.

"It's nice to at least have people looking at the team and considering that that's a possibility for us," he said.

"That's a long way from what they considered a possibility 10 weeks ago.

"I haven't had a look at everyone's draw - I don't go into it in that much detail - but suffice to say those top four teams that are currently there are pretty good teams, and we'd be going pretty well if we could knock one of them out."

Worsfold said his team would have to be wary of a Power outfit eager to atone for a poor season to date.

"They obviously wouldn't be that pleased with where they're at but they have got a focus now of working out what team they want to go forward with," Worsfold said.

Port Adelaide skipper Dom Cassisi is set to make his return from injury after being named in the extended squad, joining Jason Davenport, Brett Ebert and Daniel Stewart as inclusions.

The Eagles added Brad Sheppard, Koby Stevens, Tom Swift and Eric Mackenzie to the side that beat Adelaide, with midfielder Chris Masten the only omission at this stage.
