West Coast coach John Worsfold insists the Eagles haven't landed as an AFL force despite crushing a hapless Adelaide by 39 points on Saturday.

"We're not saying we have arrived anywhere," Worsfold said after the priceless away win entrenched West Coast in the top eight.

"We are playing at a level we're satisfied with, but knowing that we have got a lot more to do to get to where we really want."

Gifted forward Mark LeCras kicked five goals as the Eagles won 15.16 (106) to 10.7 (67) on away turf at AAMI Stadium to bank their seventh win this season.

Last year's wooden spooners appear certain to play finals for the first time since 2007 - not that Worsfold will admit it.

"Certainly not an expectation, no," Worsfold said when asked if he expected West Coast to play finals.

"I'm really pleased with what the players are doing ... (but) we have got some big challenges coming up.

"These are the challenges we need to keep testing ourselves but we're pretty pleased with the way we have met most of the challenges so far this year."

Adelaide's woes continued in their eighth loss in 11 matches with a shoulder injury to star forward Kurt Tippett.

The spearhead will have scans on his left shoulder which club officials hope is only sprained, providing Crows coach Neil Craig with further worries.

"This is a really testing time for our footy club, and it will be a really testing time for this playing group as well, because we can't keep getting injuries," Craig said.

After leading by 10 points at quarter-time, Adelaide collapsed as West Coast kicked seven unanswered goals in a scintillating second stanza.

The Eagles were sparked by veteran onballer Daniel Kerr, who feasted on sublime tap work from ruckmen Dean Cox and Nic Naitanui.

Kerr gathered a swag of damaging clearances in his influential 27 disposal display while fellow midfielders Matt Rosa (31 disposals) and Andrew Embley (29 possessions) were also prominent.

LeCras and Mark Nicoski (three goals) headlined a threatening West Coast attack while rebounding Shannon Hurn and fellow backman Sam Butler ruled in defence.

The Crows rallied with the last three goals of the third term and were 11 points down at the last change.

The home side would have been within six points early in the final term but Patrick Dangerfield sprayed a 30 metre set shot, out on the full.

West Coast capitalised on the reprieve by booting the next four goals to seal a deserved triumph.

The Eagles host lowly Port Adelaide next Sunday while Adelaide meet the Western Bulldogs in Melbourne on Friday night.
