As Jason Akermanis maintained his one-man war against the Western Bulldogs, their coach Rodney Eade claimed the Brownlow Medallist's barbs were no more relevant or hurtful than those of any other AFL outsider.

Swans coach Paul Roos has worried that Akermanis's sustained criticism of 'Dogs skipper Brad Johnson might serve to motivate the visitors to the SCG on Saturday night, but Eade denied there could be anything derived from them.

"I don't think people in the club give (Akermanis) a lot of attention or credence," he said.

"It certainly won't be used as motivation or a motivating tool, we're not that sort of group.

"People have their opinions, I think we've probably proved that opinion is wrong.

"Jason's an outside person now, so it doesn't really carry much weight."

Eade had earlier this week launched a detailed statistical defence against Akermanis's attacks on Johnson.

But on Friday Akermanis argued he had been misinterpreted, saying his view that Johnson was "finished" related to a lack of adequate defensive action.

"He should retire ... he's done, he's finished," Akermanis told reporters in Hobart.

"He is 34 and his body is not to be trusted by him or his team-mates - that's not rocket science.

"(Eade) never once addressed the actual real fact that we were talking about so he missed the whole point.

"What about his defence? He didn't want to talk about his defence.

"They're the worst tackling team in the competition."
