Former Melbourne captain Garry Lyon has expressed his great disappointment in the West Coast Eagles following their 28-point loss to Essendon last night.

From the early going, the Bombers went on the attack, leading 50-1 early into the second quarter, and Lyon has detailed how he believed the efforts from Adam Simpson's men were unacceptable.

"I wrote this down, this is what I thought, they couldn't be bothered," Lyon told SEN Breakfast.

"I know it's a very basic summation of it, but if you didn't see this game, the West Coast Eagles ran out onto the ground against a fired up Essendon, who obviously had everything to play for.

"They kicked six goals to none in the first quarter, kicked the first two of the second, so eight goals to none,"

"They could not be bothered. They didn't do enough. They were pathetic."

Former Essendon captain and club icon Tim Watson firmly believes the Eagles' side came into the game with a soft mentality and approach.

Lyon added that he can live with a performance like that from West Coast, but only if they respond strongly next week against Adelaide.
