AFL great Nick Riewoldt has launched a scathing criticism of the West Coast Eagles after Sunday's demolition at the hands of Geelong.

The reigning premiers were thoroughly outclassed in the 58-point defeat, losing almost every major statistical category, while allowing the Cats to take 16 marks inside 50 from 61 entries.

The Eagles' average losing margin this year is 48 points.

Riewoldt believes the Eagles are showing some danger signs.

"They've had three defeats this year that have all been smashings," Riewoldt told SEN Breakfast.

"Their ability yesterday to score from intercepts, it was horrible.

"They couldn't move the footy and they couldn't get it off Geelong.

"It looked like a training run.

"I think there are some legitimate concerns."

West Coast won three straight games after a shock round one loss to Brisbane, but has since been made to look vulnerable in consecutive losses to Port Adelaide on Good Friday and Geelong on Sunday night.

Those two losses have seen West Coast slide to 12th on the ladder, with a worrying percentage of 88.2 to accompany its 3-3 record.

Melbourne legend Garry Lyon was less critical of yesterday's loss, but still believes the Eagles have issues to rectify.

“I wipe that. I just wipe that game,” Lyon told SEN Breakfast.

“I’d be taking more out of last week’s loss to Port Adelaide than this week.

"Of course it’s an issue, but they just didn’t turn up.

“They were 148 possessions down. It was so one-sided. They didn’t give a yelp, West Coast."

The Eagles will look to get back on track when they play host to the Suns on Saturday night.
